This document discusses prosthetic considerations for medically compromised patients. It covers various medical conditions like arthritis, hypertension, diabetes, cardiovascular diseases, bleeding disorders, bone disorders, and psychiatric/neurological disorders. For each condition, it discusses the characteristics, impact on oral health, and prosthodontic management considerations. Special attention needs to be paid to medications, risk of infection and bleeding, wound healing ability, and stress levels of patients when providing prosthetic treatment for medically compromised individuals.
Fixed prosthodontic treatment can offer exceptional satisfaction for both patient and the dentist. Fixed Prosthodontics can transform an unhealthy, unattractive dentition with poor function into a comfortable, healthy occlusion capable of giving years of further service while greatly enhancing esthetics.
Nothing is more important in the construction of fixed partial dentures than an adequate diagnosis and a well-devised treatment plan. Although these two subjects are usually considered together. Astute dentists must recognize their subtle differences. Diagnosis is an evaluation of the condition of the patient when he presents for treatment. Treatment planning concerns the treatment procedures by which the dentist will restore the patient to an optimum state of dental health.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

This includes all relevant anatomy and clinical tests compiled from standard textbooks, Campbell,netter etc..It is comprehensive and best suited for orthopaedicians and orthopaedic residents.
3. 1. INTRODUCTION
General health factors have a great impact on prosthetic
therapy in medically compromised patients.
A detailed history including past health condition drugs and
medications taken by the patients should be recorded.
All this information should be applied to access the risks
related to specific conditions identified in the evaluation.
Certain conditions have direct bearing on management and
treatment of these patients.
6. SCREENING MEDICALLY COMPROMISED
PATIENTS
GOAL: To evaluate any source of infection that may compromise
successful dental or surgical therapy and restore optimal oral
health and function.
i. Full mouth intra-oral radiographs.
ii. Panoramic radiograph only if edentulous or not able to take
intraoral films .
iii. Thorough medical and dental history, including medications
documented on the dental chart.
iv. Physician consultation to corroborate medical history and
coordinate dental and medical care.
7. v. Recording vital signs ( BP, pulse, temperature,
respiration, weight and height).
vi. Lab investigations like CBC, BMP, CMP and bleeding
disorder tests.
vii. Initiate preventive therapy.
viii. Arrange treatment.
ix. Arrange follow-up.
8. RHEUMATOID ARTHRITIS
Rheumatoid arthritis (RA) is a chronic inflammatory
disease characterized by synovial inflammation that
results in destruction of joint tissues.
ETIOLOGY
The cause of RA is not known, although its etiology appears
to be multifactorial and may involve infectious, genetic,
endocrine and immunological causes.
It is believed to be caused due to sudden influx of T cells
into the affected joints and is followed by an increased
number of macrophages and fibroblasts, drawn by
the release of cytokines, particularly IL-1, and TNF-α.
9. The characteristics of this
disease are bilateral chronic
inflammation of the synovium, a
condition known as synovitis.
This inflammatory response
particularly affects small joints
of the upper and lower
extremities.
In addition to the typical pattern
of inflammation, patients with
RA may experience systemic
manifestations such as fatigue,
loss of appetite, weakness and
vague musculoskeletal pain.
10. Nonsteroidal anti-inflammatory drugs are the current
mainstream "first-line"treatment.
Corticosteroids, another option, have both anti-
inflammatory and immunosuppressive effects.
Second-line" or disease-modifying antirheumatic drugs, or
DMARDs like gold, sulfasalazine,hydroxychloroquine.
Methotrexate has become a popular treatment choice
recently because of its immunosuppressive and anti-
inflammatory effects.
TREATMENT
11. DENTAL MANAGEMENT
i. It is essential that the dentist keep himself or herself
updated as to the drugs the patient with RA is currently
receiving, their possible side effects and interactions with
other drugs.
ii. Oral hygiene procedures may become difficult because of
reduced manual dexterity. Such patients may have
particular difficulty in removing or inserting removable
partial dentures .
iii. Fixed solutions may be a more favourable treatment
modality with regard to reduced/impaired manual dexterity
12. iv. Advantages of implant placement in conjunction with fixed
prostheses were especially noted in patients suffering from
other systemic autoimmune diseases such as Sjo¨gren’s
syndrome.
v. Patients with severe RA who have had joints surgically
replaced with prosthetic joints may require prophylactic
antibiotic therapy before invasive procedures.
v. The temporomandibular joints can be affected in this disease.
The problem encountered in the prosthodontic rehabilitation of
patients with Rheumatoid arthritis of TMJ is
a. Changes in occlusion. b. Jaw relation.
13. a. Changes in occlusion:
As the joint tissue are more susceptible to increased
loading, the prosthetic reconstructions should be aimed at
giving unloading appliances and improve the distribution of
occlusal force.
b. Jaw relation:
There is a difficulty in recording an acceptable jaw
relationship because of the destruction of joint tissues.
There is a large distance between the most returned and the
intercuspal position i.e., CR-CO.
In such situations a muscularly relaxed and comfortable jaw
position should be chosen and tried in provisional
constructions before the permanent rehabilitation is
completed.
14. Osteoarthritis of temporomandibular joint
Problem in complete denture construction, for
mandibular movements are painful.
In extreme conditions surgery may be indicated.
Special impression trays are often necessary because of
limited access from reduced ability to open the jaws.
Jaw relation records are difficult to record and repeat,
and occlusal correction must be often made because of
subsequent changes in the joint.
16. PROSTHODONTIC MANAGEMENT
i. Prosthodontic treatment approach in a hypertensive
patient should be planned meticulously.
ii. The blood pressure must be controlled before any
Type 3 or 4 dental treatments.
iii. The prescription of anxiolytic agents may prove
necessary in particularly anxious patients (5-10mg of
diazepam the night before and 1-2 hours before the
appointment) before dental treatment.
iv. An early morning appointment with minimum waiting
room time.
17. iv. LA with vasoconstrictor should be avoided or used in low doses
in patients with uncontrolled hypertension.
v. The sharp edges of the removable partial dentures should be
trimmed off and polished well.
vi. Fabricating a complete denture demands utmost care to avoid
causing soft tissue abrasion. Certain antihypertensive drugs are
associated with xerostomia which in turn hamper the retention
and stability of the complete dentures.
vii. In such patients artificial salivary lubricants should compensate
the effect of xerostomia for better post-therapy results .
18. viii. Due to higher concentrations of epinephrine in gingival
retraction cords used for prosthetics impressions and its rapid
uptake in circulation, the use of epinephrine for gingival
retraction in patients with cardiovascular disease should be
carefully administered.
ix. To minimize gingival bleeding, the margins of the preparation
should be kept supragingival.
x. During treatment, sudden changes in the body position
should be avoided, as they can cause orthostatic hypotension
as a side effect of the antihypertensives.
19. DIABETES MELLITUS
Diabetes mellitus is a disease of glucose, fat & protein
metabolism resulting from impaired insulin secretion, varying
degree of insulin resistance or both.
20. According to American diabetic association (ADA): Fasting
blood sugar (FBS) > 126 mg/dl or Post random blood sugar
(PRBS) > 200mg/dl.
Symptoms like polyuria, polydypsia, polyphagia, weight loss
and visual disturbances are experienced by diabetic patients.
.
22. PROSTHODONTIC MANAGEMENT OF DIABETIC DENTAL
PATIENT
1. Medical History:
It is important to take proper medical history of the patient’s
blood glucose levels, medication, dosage and timing of
medication taken.
Make sure the patient had done their blood glucose level test
prior to the treatment.
2. Diet:
It should be ensured that patient has had his/her breakfast and
medication before treatment.
23. 3. Scheduling of the Patient’s Visit:
Diabetic patients should be scheduled preferably in the
morning.
4. In RPD:
All components of RPD must be designed appropriately such
that prosthesis is tissue friendly.
Proper oral hygiene and denture hygiene or maintenance
instructions should be given to the patients.
24. 5. In CD:
Denture border and tissue surfaces of the dentures should be
smooth without any sharp nodules or over extensions to
prevent tissue damage.
Impressions should be taken in mucostatic technique without
pressure.
Concept of neutral zone technique can be employed to reduce
the bone resorption .
Proper oral hygiene instructions can be given to patients to
avoid fungal infections.
As there is decrease denture retention due to less salivat- ion,
frequent sipping of water and use of sugarless gums may help
them to maintain salivary flow.
25. 6. In FPD:
It is better to keep the finish line supragingival to avoid
damaging soft tissue.
The chamfer margin is a better option as it applies less
force or stress on weakened tooth.
Ante's law should be obeyed as the diabetic patient more
prone for periodontal infection.
Proper flossing should be done to maintain the oral hygiene.
26. During tooth preparation, care should be taken to avoid
trauma to the soft tissue as diabetes patients have poor
wound healing.
Hygienic pontic should be preferred as much as
possible for ease of cleansing action.
27. 7. In Implant or Implant Supported Dentures:
As this condition is commonly associated with impaired wound
healing, any surgical procedure like pre-prosthetic surgery or
dental implant placement should be performed only when the
diabetes is in well controlled state.
Antimicrobial cover using penicillin, amoxicillin, clindamycin or
metronidazole should be provided before and after the implant
surgery.
These patients should also quit smoking, optimize oral hygiene
measures and use antiseptic mouthrinses to prevent the
occurrence of periodontal and peri-implantitis.
Patient should maintain their sugar level even after the surgical
placement of implants.
28. CARDIOVASCULAR DISEASES
Cardiovascular diseases make up the most prevalent
category of systemic disease in almost all countries, and
increase in prevalence with age.
Myocardial infacrtion isprolonged ischemia or lack of
oxygen resulting from a deficiency in the coronary arterial
blood supply that causes injury to the myocardium .
Angina is a symptom of ischemic heart disease produced
when myocardial blood supply cannot be sufficiently
increased to meet the increased oxygen requirements that
result from coronary artery disease.
29. o Angina pectoris is a symptomatic expression of temporary
myocardial ischemia.
o The classical symptom of retrosternal pain often develops
during stress or physical exertion, radiates to the shoulders,
left arm, or mandible, or right arm, neck, palate, and tongue.
o Bacterial endocarditis is an infection of the heart valves or
the endothelial surfaces of the heart.
o Atherosclerosis is a progressive disease process that
involves the large- to medium-sized arteries.
o It can lead to ischemic lesions of the brain, heart or
extremities, and can result in thrombosis and infarction of
affected vessels, leading to death.
30. GENERAL AND PROSTHODONTIC MANAGEMENT
For patients with cardiovascular diseases short
appointments and a stress-reduction protocol are indicated,
including: -
vital signs monitoring: (heart rate, blood pressure, etc);
stress reduction protocol; - 2-5mg diazepam on the night,
before treatment and 1 hour prior to treatment;
nitrous oxide+O2 or O2 (3 lit/min) via nasal canula;
premedication with nitroglycerin if needed;
31. Check whether the patient is using anticoagulants (including
aspirin ).
Dental /prosthetic treatment should not be carried out without
consultation with their physician.
Consider possible limitation of epinephrine for gingival
retraction.
Patients with arteriosclerotic cerebral disease often have
reduced motor skills and may be absent – minded and
confused.
They have difficulty coping with removable dentures , the
natural dentition should be remained if possible.
32. o Patients who take antidepressant drugs after a stroke may
suffer from several collateral effects . They might have
problems with stability and retention of their removable
prosthesis and should be made to use adhesive pastes.
IMPLANT MANAGEMENT
Angina pectoris:
i. The risk category for the typical angina patient is ASA
III and for recent or unstable angina is ASA IV.
ii. The vital signs have to be monitored during the procedure
and the patient is instructed to have nitroglycerine.
33. iii. The implant surgery is performed with nitrous oxide.
The use of vasoconstrictors is limited to 0.04 to
0.05mg epinephrine.
iv. Patient with moderate angina should be given
nitroglycerine sublingually just before advanced
operative or simple to moderate implant surgery.
v. Antianxiety sedation with supplemental oxygen are
also required.
v. Patients with severe angina are limited to
examination procedures and is an absolute
contraindication for elective dental surgery.
34. Myocardial infarction:
i. Patients with MIT in preceding 6 months can have
dental examination, but treatment has to postpone
for 6 months.
ii. Longer procedures should be segmented into
shorter appointments .
iii. Elective implant procedures should be postponed
for at least 12 months following MI.
iv. Hospitalization is an accepted modality for all
advanced surgical procedures regardless of time
elapsed after a MI.
35. Subacute Bacterial Endocarditis:
i. The Endocarditis prophylaxis are recommended in high
risk patients for procedures like dental implant placement,
sub gingival placement of antibiotic fibers or strips.
ii. The Endocarditis prophylaxis not recommended for the
placement of removable prosthodontic appliances and
making oral impressions.
iii. Implants may be contraindicated for patients with a limited
oral hygiene potential and for those with history of stroke.
36. iv. Intramucosal inserts are also contraindicated for many of
these patients because a slight bleeding can occur on a
routine basis for several weeks during the initial healing
process.
v. Endosteal implants with an adequate width of attached
gingiva are the implants of choice for patients in this
group need implant supported prosthesis.
37. Patients undergoing anticoagulant therapy
The main objective of this therapy is to reduce the
occurrence of thromboembolism .
It is usually recommended in all patients with
thromboembolic risk
in patients after angioplasty and stent placement,
bypass surgery
prosthetic heart valve placement.
38. The reduction of the perioperative warfarin dosage or the
discontinuation of the anticoagulant treatment 2 or 3 days
before the oral surgery procedure has been a widely used
strategy (Mulligan & Weitzel 1988).
According to Scully et al. (2007), the placement of an implant
in patients undergoing OAT can be regarded with comparable
or even less surgical trauma than the extraction of three
teeth, provided that this procedure does not involve
the harvesting of autogenous bone grafts,
the raising of extensive flaps
placing implant in sites where there is a risk during the
osteotomy preparation of extending outside the bony
envelope.
39. Another strong recommendation is the avoidance of drugs
that may increase the bleeding tendency . Of particular
importance are:
Analgesics, because aspirin and other non-steroidal
antinflammatory agents significantly prolong the
bleeding time by preventing platelet aggregation and
thus increasing the activity of warfarin.
Antibiotics, because some molecules such as
erythromycin, clarithromycin or metronidazole are able to
augment the anticoagulant effect of warfarin.
(What influence do anticoagulants have on oral implant
therapy? A systematic review)
40. BLEEDING DISORDERS
Bleeding disorders can be classified as coagulation factor
deficiencies, platelet disorders, vascular disorders or
fibrinolytic defects.
Among the congenital coagulation defects, hemophilia A,
hemophilia B (Christmas disease) and von Willebrand’s
disease are the most common.
Hemophilia comprises a group of hereditary bleeding
disorders caused due to the deficiency of one or more
clotting factors.
41. It is broadly divided into hemophilia A, B, and C, which
occur due to deficiency of factors VIII, IX, or XI (F VIII, F IX,
F XI) respectively
The normal plasma concentration of factors is 50 to 100
IU/dL. When the plasma concentration falls below 1 IU/dL,
disease manifestations are severe; ranges between 2 and
4 IU/dL are moderate and a range between 6 and 40 IU/dL
is mild.
Prosthodontic rehablitation
Removable prosthodontic procedures do not usually
involve a considerable risk of bleeding.
Trauma should be minimized by careful post-insertion
adjustments. Oral tissue should be handled delicately
during the various clinical stages of prosthesis fabrication to
reduce the risk of ecchymosis
42. BONE DISEASES
1. Osteoporosis
It shows a decrease in skeletal mass, increased
microstructural deterioration without alteration in the
chemical composition of bone.
Management: Designing complete denture requires
special consideration for these patients to preserve the
underlying tissue structure as much as possible.
Prosthodontist are in a strategic position to intercept early
evidence of osteoporosis and educate the geriatric patient
towards good nutrition
Estrogen therapy can retard severe bone demineralization
caused by osteoporosis in women.
43. Adequate dietary calcium intake is essential. Recommended
calcium intake of 800 mg / day for average person and 1500
mg for the postmenopausal women.
Dental implant management:
Although osteoporosis is significant factor for bone volume
and density, it is not a contraindication for dental implants .
The bone density does affect the treatment plan, surgical
approach, length of healing and loading.
Implant designs should be greater in width and coated with
hydroxyapetite to increase bone contact and density.
44. 2. Osteitis deformans :
It is a slowly progressing
chronic disease where
osteoblasts and osteoclasts
are involved with
predominance of its
osteoblastic activity.
Characterized by excessive,
uncoordinated phases of
resorption and deposition of
osseous tissue in single /
multiple bones.
The jaws are affected in
20% of the cases .The
maxilla is more often
involved than mandible.
45. ORAL MANIFESTATIONS
Pain with bilaterally symmetrical swelling of the involved
bone.
Leontiasis ossea - facial bone involvement
Headache, blindness, deafness.
Difficulty in wearing old dentures.
Diastema, loosening of teeth, malocclusion may be seen.
Necrosis of gingiva over the underlying bone may occur
due to excessive internal pressure.
Pathologic fractures also may occur as bone becomes very
weak.
46. MANAGEMENT
Prosthodontists treating patients with this disease
must be aware of complaints of pain with sudden onset
accompained by swelling.
Oral implants are contraindicated in the regions affected
by this disorder .
The remakes and adjustment of dentures are needed
due to continual enlarging and changing of supporting
structure especially of the maxillary tuberosity.
47. FIBROUS DYSPLASIA
Fibrous dysplasia is a disorder in which fibrous connective
tissue replaces areas of normal bone in an unorganized
arrangement.
It is found twice as often in women than it is in men.
Oral manisfestations :
Twice as commom in maxilla than mandible
Monostotic fibrous dyplasia begins as a painless,
progressive lesion.
Teeth may move as a consequence of progression.
Predisposition to fracture.
Slow healing and increased incidence of infection.
48. IMPLANT CONSIDERATION
The implant placement is contraindicated in the regions of
this disorder because of lack of bone and increased
fibrous tissue which reduces rigid fixation of the implant.
Excision of the fibrous dysplasia areas is usually the
treatment choice.
After the condition is corrected long term, the area may
receive an implant.
50. Dental considerations :
Do not use drugs toxic to the kidney i.e.
acetaminophen.
Alter dosage form when using drugs eliminated by
the kidney i.e. penicillin (often reduced to 500 mg
two times per day versus four times per day)
If patient on renal dialysis, dental treatment should
be done on the day following dialysis.
If patient has kidney transplant,
immunosuppression protocol considerations must
be followed.
51. NEUROLOGIC AND PSYCHIATRIC
CONDITIONS
The neurologic conditions like parkinson’s disease, stroke,
and seizures require thorough history and list of
medications. A consultation with physician is helpful in
treating these patients.
Prosthodontic considerations :
The patient with lack of salivary control should be
positioned in a semi reclined position to avoid pooling of
salvia, airway obstruction, and aspiration.
When dentist is providing replacement complete denture,
duplication technique should be used in order to retain the
learned muscle control of familiar denture.
52. o In patients who have had cerebrovascular stroke, the
incidence and the risk of stroke after effects such as
dysphagia, hypoaesthesia, apraxia, reduction in muscle
tone, with a consequent reduced control of mouth and
tongue movements, are significantly high.
o Additionally, long-term denture wearers usually have a high
level of bone resorption, making the denture inadequate in
fit and function, so the old dentures should be replaced.
o In order to make the impression, the old denture may be
used as a tray.
53. o An additional silicone material with low viscosity should be
used as it is extremely manageable, tolerable and barely
irritable.
The weakness of the muscles of mastication, such as the
buccinator muscle, alters the dynamics of eating, causing
food stagnation in the fornix area.
In order to solve this problem, the outer surface of the
denture may be modified both to improve its retention (the
lower part) and to reduce the amount of food that remains
between the buccinator muscle and the prosthetic
modification.
In those patients suffering from hemiplegia, we may have
difficulties even in inserting and removing the denture.
54. Another problem which might occur is the presence
of facial asymmetry. In order to achieve facial
harmony, we may change the vestibular denture
flange and add some acrylic resin to expand it.
Great care has to be taken in assessing the
midline, the aesthetic facial lines and the occlusal
plane.
55. CHRONIC OBSTRUCTIVE PULMONARY
DISEASES
Two common forms of COPD are emphysema and
chronic bronchitis.
Patients with COPD may have a combination of
chronic cough, sputum production and shortness of
breath.
Dental implant management
Patients with difficulty breathing only on significant
exertion and normal lab blood gases are at minimal
risk and may follow all restorative or surgical
procedures with normal protocols.
56. Dental management of COPD patients may require
repositioning the patient from the normal supine
position.
Supplemental oxygen should be administered
throughout the dental procedures.
Patients with difficulty in breathing on exertion in
general are at a moderate risk .
For type 2 procedures these patients need a hospital
setting.
57. If the patient is on bronchodilators , no epinephrine or
vasoconstrictors should be added to the anesthetics or
gingival retraction cord.
Adrenal supression should be evaluated for any patient
on corticosteroid therapy within the past year.
Patients at high risk are those with previously
unrecognized COPD, acute exacerbation or dyspnea
at rest.
In these patients elective moderate procedures or
prosthetic procedures are contraindicated.
58. LIVER DISEASES
Cirhossis is the 3rd leading cause of death in young
men between the ages of 35 and 54years
It occurs as a result of injury to the liver with
resultant loss of liver cells and progressive scarring.
Major cause is alcoholic liver disease.
59. Dental implant management
Patient with no abnormal lab values for CMP, CBC, PTT
and PT are at low risk.
A normal protocol is indicated for all procedures (type 1
to type 4 ).
Patients with an elevated PT of less than 1.5 times the
control value, or bilirubin slightly affected are at a
moderate risk.
These patients should be refered to their physician and
use of sedatives and tranquilizers may need their
clearance.
60. Strict attention to homeostasis is indicated.
Moderate to advanced surgical procedures may
require hospitalization(Type 3 and 4 ).
Elective dental procedures such as implants are
contraindicated in patients at high risk.(PT of more
than 1.5 times the control value).
61. Dental implant management HIV positive patients with AIDS:
a) The distinction should be made between asymptomatic HIV
positive patient and AIDS patient with varying degrees of
immunosupression with reduced T lymphocytes.
b) The change from health to disease or from asymptomatic HIV
positive phase to AIDS is indicated by decreasing T cell
lymphocyte counts and the onset of opportunistic infections.
c) The individuals whose HIV- positive status is identified soon
after infection, general dental care can often be provided for
many years without particular concern regarding the patient
overall health status along with rigid infection control
guidelines.
62. HEPATITIS B
In dentistry, viral hepatitis B is considered to be
dangerous due to cross infection risk after sharp
injuries.
The main reason that chronic viral hepatitis may be
of interest for the outcome of the implant restoration
may be when the bone quality and quantity is
altered.
It is important factor before placing immediately an
implant in the socket, post-extraction, to have a
thorough cleaning of the cavity.
63. Post-surgery the patient advised to rinse the mouth
with 0.12% chlorexidine antiseptic solution for a
week.
hepatitis B carriers were not considered to be a
group of relative or absolute contraindication for
implantology.
64. SUMMARY
Various systemic diseases play a pivotal role in deciding
treatment options in dentistry.
The prosthodontic procedures should not be planned until
the systemic status of the patient is evaluated.
Treatment planning is a consideration of all the diagnostic
findings, systemic and local which influence the surgical
preparations of the mouth, impression making, maxilla-
mandibular relation records,occlusion, form and material
in the teeth.
So the prosthodontist must not only be aware of the
systemic factors but also consider them in the treatment
plan.

The key to successful prosthetic management and rehablitation of medically compromised patient is accomplished by
and the typical systemic disorders reported in a population of people over 65 are arthritis (44%), hypertension(31%),cardiovascular disease (25%), diabetes
(7%) and other health problems (87%)(Mac Entee ,1994).
It was designed to estimate the medical risk presented by a patient reciveing general anesthesia for a surgical procedure.
This cytokine release and subsequent migration of cells is thought to be responsible for the chronic inflammation, and characteristic destructive changes in rheumatoid joints.
(after extremities) it often leads to the deterioration and eventual destruction of articular cartilage and juxta-articular bone, as well as to an
inflammatory process surrounding tendons, all of which result in deformities of the affected joints.
ii. So Replacement therapy for adrenally suppressed people may be necessary to prevent cardiovascular collapse, as their response to surgical stress may include a precipitous drop in blood pressure.
The problem of soreness of the oral mucosa in conjunction with removable mucosa-supported prostheses and dry-mouth sensation is well known and may constitute a particular problem for (elderly) patients that could be avoided or reduced by exclusive implant support of dentures.(Payne et al. 1997).
The removable denture in the lower jaw is not only beneficial for chewing but also for unloading the diseased joints.
History should cover specific aspects like the duration of hypertension, medication and patient compliance with regard to antihypertensives, other associated co-morbid conditions, current oral disease, past dental treatment including its outcome, complications during treatment
preferably should be fabricated with flexible material.
. Hyposalivation was also found as one of the clinical manifestations in hypertensive patients which related to the sustained increase in both systolic as well as diastolic blood.
Many antihypertensive drugs like ACEIs, thiazide diuretics, loop diuretics, calcium channel blockers and clonidine are associated with xerostomia. Patients taking diuretics show hyposalivation.
•HbA1C is evaluated to check overall glycemic control for a period of 3 months.It is very important to evaluate proper medical history and assess glucose level at the initial appointments in all the patients older than 45 years of age
Since endogenous cortisol level is higher during morning time which in turn increases blood glucose level.
STRESS OF SURGERY MAY PROVOKE COUNTERREGULATORY HORMONES AND IMPAIRS INSULIN FUNCTION CAUSING HYPERGLYCEMIA THUS
Stress reduction protocol for patients IS RECOMMENDED
PATIENTS with HbA1C 7 GLUCOSE LEVEL LESS THAN 150 need sedation and antiobiotics for type 3 or 4 treatments.
The end result of mi is cellular death and necrosis.
angina is caused due to discrepancy between mycardial oxygen demand and the amount of oxygen being delivered through the coronry arteries.
Stress and anxiety related to dental visit may precipitate angina attack
It is the result of the growth of bacteria on damaged or altered cardiac surfaces. The microorganism most often associated is alpha hemolytic streptococcus viridans.
Dental procedures causing tranisent bacterimia are a major cause of bacterial endocarditis.
these patients are difficult to treat and protracted and complex treatment should be avoided
High risk patients : artificial prosthetic valves prophylaxis 2g amox 60mins before orally
h/o bacterail endocarditis 2g ampicillin iv or im 30mins before (patients who cant take oral medications)
Unrepaired Cynatic congenital heart disease allergc to penicillin 600mg clindamycin
With implant surgery becoming the standard of care to replace missing teeth and with more and more dental practices increasing their exposure to oral surgery, the dental professional must be fully prepared for the management of such patients and the potential complications
Hemophilia A is an X-linked recessive hereditary disorder and most common of the three .
Normal PTNo type of dental treatment is done in the following scenario:
a) If bleeding time greater than 10 minutes
b) If platelet count less than 60,000
c) If PTT greater than 45 seconds
d) If PT greater than 22 seconds
e) If INR greater than 3.5
It is, therefore, recommended to thoroughly evaluate the jawbone quality prior implant and modify treatment planning if indicated
The tissue is hypocellular so healing is imapired
Depending on the severity of disease, orthopnea may result.The patient can be placed in the most recumbent position so that the breathing is comfortable.
Bovine collagen, topical thrombin, or additionla sutures are indicated for homeostasis.
ELECTIVE IMPLANT THERAPY CONTRAINDICATED IN PATIENTS WITH SYMPTOMS OF ACTIVE ALCOHOLISM.
Fresh frozen plasma to correct the pt value
Platlet transfusion for even scaling procedures
Any left granulomatous or cystic tissue would affect the osseointegration process by increasing the failure risk.
However it is meaningful to avoid such a surgery in active acute or active chronic hepatitis
