Orthognathic surgery involves correcting dentofacial deformities through surgical procedures on the jaws and chin. It requires a combined surgical and orthodontic approach to achieve optimal results. Surgery is indicated for severe malocclusions that cannot be treated through orthodontics or growth modification alone. The decision to pursue surgery or camouflage treatment must be made before starting treatment, as the orthodontics differ significantly between the two approaches. Computer simulation can help patients understand treatment options and decide between camouflage and surgery.

Mouth preparation refers to procedures that must be accomplished before fixed prosthodontic treatment can be properly performed.
Rarely are crowns or fixed prosthodontic treatment provided without initial therapy because what causes the need for the fixed prosthesis also promote other pathological processes (caries and periodontal disease are the most common).
Failure of fixed prosthesis often results from inadequate or incomplete mouth preparation.

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.

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.

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

Orthognathic surgery new microsoft power point presentation
1. Orthodontics and orthognathic
surgery
Orthognathic surgery is concerned with the
correction of dento-facial deformity. In the
vast majority of cases a combined surgical
and orthodontic approach is required to
achieve an optimum result.
2. Indications for Orthognathic
SurgerySeverity of skeletal and dental malocclusion
When growth modification can not be achieved
Esthetic and psychosocial considerations
Good general health status (mild, controlled systemic
disease)
3. For patients whose orthodontic problems are so
severe that neither growth modification nor
camouflage offers a solution, surgery to realign
the jaws or reposition dentoalveolar segments is
the only possible treatment.
Surgery is not a substitute for orthodontics in
these patients. Instead, it must be properly
coordinated with orthodontics and other dental
treatment to achieve good overall results.
4. The patient's perception of the
problem
appearance
masticatory difficulties
speech
traumatic overbite
temporomandibular joint dysfunction
5. CAMOUFLAGE VERSUS SURGERY
The decision for camouflage or surgery must be
made before treatment begins, because the
orthodontic treatment to prepare for surgery
often is just the opposite of orthodontic treatment
for camouflage
It is a serious error to attempt camouflage on the
theory that if it fails, the patient can then be
referred for surgical correction. At that point,
another phase of "reverse orthodontics" to
eliminate the effects of the original treatment will
be required before surgery can provide both
normal jaw relationships and normal occlusion.
6. Extraction of Teeth and the
Camouflage/Surgery Decision
The critical importance of deciding on camouflage or
surgery at the beginning of treatment is illustrated by
the difference in extractions needed with the two
approaches
In camouflage, extraction spaces are used to produce
dental compensations for the jaw discrepancy and the
extractions are planned accordingly.
7. • Some degree of dental compensation accompanies
most skeletal jaw discrepancies, even without
treatment.
• If the jaws are to be repositioned surgically, this
dental compensation must be removed. Otherwise,
when the teeth are placed in normal occlusion, the
jaw discrepancy will not be totally corrected, and
dental interferences make it almost impossible to put
the jaws in their proper relationship to each other
8. Computer Simulation of Alternative
Treatment Outcomes
It always has been a moral and ethical imperative to
allow the patient to make important decisions about
what treatment he or she will accept
Computer image predictions are particularly valuable
in helping patients decide between camouflage and
surgery, and in planning surgical treatment.
9. The patient can view the impact on the soft tissue
profile of orthodontic camouflage versus surgery
when these are realistic treatment alternatives
also view the effect of varying amounts of surgical
change—more or less mandibular advancement, for
example, or the effect of genioplasty or rhinoplasty
in addition to change in jaw position.
11. The characteristics of a patient who would be a good
candidate for camouflage treatment are:
• Too old for successful growth modification
• Mild to moderate skeletal Class II or mild skeletal Class III
• Reasonably good alignment of teeth (so that the extraction
spaces would be available for controlled anteroposterior
displacement and not used to relieve crowding)
• Good vertical facial proportions, neither extreme short
face (skeletal deep bite) nor long face (skeletal open
bite)
12. Camouflage treatment designed to correct the occlusion
despite jaw relationship problems should be avoided in :
Severe Class II , moderate or severe Class III , and vertical
skeletal discrepancies.
Patients with severe crowding or protrusion of incisors,in
whom space created by extractions will be required to
achieve proper alignment of the incisors.
Adolescents with good growth potential (in whom growth
modification should tried first) or non-growing adults with
more than mild discrepancies (in whom orthogenetic surgery
usually offers better long-term results ).
13. ORTHODONTIC CAMOUFLAGE OF
SKELETAL MALOCCLUSION
Acceptable Results Likely
• Average or short facial pattern
• Mild anteroposterior jaw discrepancy
• Crowding <4-6 mm
• Normal soft tissue features (nose, lips, chin)
• No transverse skeletal problem
Poor Results Likely
• Long vertical facial pattern
• Moderate or severe anteroposterior jaw
discrepancy
• Crowding >4-6 mm
• Exaggerated features
• Transverse skeletal component of problem
14. COMMON SURGICAL PROCEDURES
As aesthetics are of major importance, where possible
an intra-oral approach should be used to avoid
unsightly scars. Segmental procedures have an
increased morbidity, as damage to the teeth or
disruption of the blood supply to a segment is more
likely.
15. Maxillary procedures
• Segmental procedures The Wassmund technique
involves movement of the upper premaxillary
segment of incisors and canines as a block,
• Le Fort I This is the most widely used technique. The
standard approach is a horseshoe incision of the
buccal mucosa and underlying bone, which results in
the maxilla being pedicled on the palatal soft tissues
and blood supply.
• Le Fort II to achieve mid-face advancement
Le Fort III the whole mid-face including the zygomas
is separated from the cranium
20. Documentation
Standard records should include:
• a detailed description of the patients' concerns
• facial and dental photographs
• dental study casts usually based in centric occlusion
• an orthopantomogram (OPT) and lateral cephalogram,
with a postero-anterior (PA) cephalogram for those patients
presenting with an asymmetry
• a detailed dental history and examination
• a detailed medical history and examination.
21. Timing of Surgery
Usually done when all growth is complete
Assessed by superimposition of serial lat cephs
Can be performed when growth is not yet complete in
cases of psychosocial problems or great severity when
function is compromised (i.e. breathing, chewing)
22. Orthognathic Surgery
Correction of A-P relationships:
maxillary advancement
retraction of anterior maxillary segment
mandibular advancement
mandibular setback
double jaw surgery
23. • The maxilla and mandible can be moved anteriorly and
posteriorly as indicated by the red arrows in these line
drawings.
• Anterior movements of the mandible greater than 10 to 12 mm
create considerable tension in the investing soft tissues and
tend to be unstable. Anterior movement of the maxilla is
similarly limited to 7-8 mm in most circumstances.
• Posterior movement of the entire maxilla, though possible, is
difficult and usually unnecessary. Instead, posterior movement
of protruding incisors up to the width of a premolar is
accomplished by removal of a premolar tooth on each side,
followed by segmentation of the maxilla.
• Although the maxilla can be advanced more than it can be
retracted, the possibility of relapse or speech alteration from
nasopharyngeal incompetence increases with larger
movements.
24. Orthognathic Surgery
Correction of Vertical Relationships:
maxillary impaction/intrusion
maxillary extrusion
mandibular ramus surgery
25. The surgical movements in the vertical dimension are
indicated by the red arrows on this diagram of the skull. The
maxilla, mandibular angles, and chin can be moved upward
reliably, while downward movement of the maxilla by bone
grafting is less predictable (arrow with single asterisk).
Downward movement of the chin is possible in combination
with slight advancement. Lengthening the ramus (arrow with
double asterisks) stretches the muscular sling and usually
results in relapse
26. Distraction Osteogenesis
• Distraction osteogenesis is based on manipulation of
a healing bone, stretching an osteotomized area
before calcification has occurred in order to generate
the formation of additional bone formation and
investing soft tissue
• Distraction osteogenesis is useful for the correction of
severe deformity in the growing child and it is hoped
will help to reduce the number of surgical procedures
previously required to treat these children.
27. The advantages of distraction are
that
• (1) larger distances of movement are possible than
with conventional orthognathic surgery, and the
forces also act upon the surrounding soft tissues
leading to adaptive changes termed distraction
histogenesis
• (2) deficient jaws can be increased in size at an earlier
age.
• The great disadvantage is that precise movements
are not possible. With distraction, the mandible or
maxilla can be moved forward, but there is no way to
position the jaw or teeth in exactly a pre-planned
place,
28. Orthodontic Appliance
Considerations
• In contemporary surgical-orthodontic treatment, a
fixed orthodontic appliance has three uses: to
• (1) accomplish the tooth movement needed in
preparation for surgery;
• (2) stabilize the teeth and basal bone at the time of
surgery and during healing; and
• (3) allow the necessary postsurgical tooth movement
while retaining the surgical change
29. Pre Surgical Orthodontic Objectives
To level and align the arches and make them
compatible so that the teeth do not interfere with
placing the jaws in their planned relationship
to resolve crowding and/or spacing
to establish anteroposterior and vertical position of
incisors (decompensate) to place teeth relative to
their own supporting bone
30. It is important to forewarn the patient that the
presurgical orthodontic phase may make their
appearance worse as any dento-alveolar
compensation is reduced
Presurgical orthodontics usually takes between 12 and
18 months depending upon the complexity of the case
31. Preparation for Surgery
• Removal of third molars 6 months before
mandibular osteotomy
• Check for any TMJ problems
• Manipulate models mounted in an articulator to
check for interferences and occlusion
• Model surgery is often carried out to determine the
amount and site of bone removal and to fabricate
inter-occlusal wafers Splint fabrication (1 or 2 splints
usually 1 to 2 weeks before surgery)
32. Post Surgical Orthodontic Treatment
4-6 weeks: reinitiate orthodontic tx (after range of
motion and stability are achieved)
remove splint
change to light wires and light vertical elastics
treatment usually completed in 4 to 12 months (average
6 months)
33. Relapse and Stability
Rigid fixation has improved stability
Stability is mostly influenced by the pattern of rotation
of the mandible as it is advanced
Advancement of maxilla and/or mandible will stretch
soft tissues promoting relapse
The more advancement needed, the greater the
probability for relapse
patient is compliant with all aspects of treatment,
particularly postsurgical wear of elastic traction
34.
35. In this context, very stable means better than a 90% chance of
no significant postsurgical change; stable means better than an
80% chance of no change and major relapse quite unlikely;
problematic means some degree of relapse likely and major
relapse possible.
It is interesting to note that the key procedures in surgical
treatment of Class II problems (superior repositioning,
mandibular advancement and their combination) are quite
stable. In Class III treatment, maxillary advancement is the most
stable procedure, while downward movement of the maxilla
and mandibular setback remain problematic).
