Abstract: Corticotomy-assisted orthodontic treatment is an established and efficient orthodontic technique that has recently been studied in a number of publications. Corticotomy facilitated orthodontics have been employed in various forms over speed up orthodontic treatment It involves selective alveolar decortication in the form of decortication lines and dots performed around the teeth that are to be moved. It is done to induce a state of increased tissue turnover and a transient osteopenia, which is followed by a faster rate of orthodontic tooth movement. This technique has several advantages, including faster tooth movement, shorter treatment time, safer expansion of constricted arches, enhanced post-orthodontic treatment stability and extended envelope of tooth movement. The aim of this article is to present a comprehensive review of the literature, including historical background, contemporary clinical techniques, indications, contraindications, complications and side effects. Keywords: Corticotomy, decortication, review, orthodontic treatment

There are several advantages of an immediate denture. The most important factor is that you will never need to appear in public without teeth. ... When an immediate denture is inserted at the time of extraction, it will act as a Band-Aid to protect the tissues and reduce bleeding.
Corticotomy facilitated orthodontics
Although the art and science of orthodontics have progressed significantly over the past 100 years, relatively little has been done to enhance the rate at which tooth movement occur. Many methods have been done to enhance the rate of tooth movement. These methods include the injection of biologically active peptides, the use of magnets and even the application of electric current and corticotomy.
Corticotomy: is slight penetration through the cortical bone and did not be confused with the osteotomy. Or defined as incision made into the cortical bone.
This penetration or incision leads to decrease the resistance of the alveolar and diminish physical alveolar bone contact that accelerates the rate of tooth movement.
Several authors have described rapid tooth in conjunction with corticotomy surgery as movement by bony (Block). Kole6 was the first describe the corticotomy as a surgical procedure in which one tooth or group of teeth with the adjacent bone is repositioned in one step. But others prefer to call this osteo-corticotomy or intra alveolar segmental osteotomy, reserving the term corticotomy for a technique in which cuts are made in the buccal cortical plate of bone. So that the segment to be moved orthodontically is held only by cancellous trabeculea and palatal cortical bone.
Kole in 19596 reported combining orthodontics with corticotomy surgery and complete the active tooth movement in adult orthodontic cases in 6 to 12 weeks.
The inter-proximal corticotomy cuts were extended through the entire thickness of the cortical layer, just barely penetrating the medullary bone.
The vertical cuts were connected beyond the apices of the teeth with horizontal osteotomy cut extending through the entire thickness of the alveolus, essentially creating blocks of bone in which one or more teeth were embedded, using the crowns of the teeth as a handles. Kole believed that he was able to move the blocks of bone some what independly of each other because they were only connected by less-dense medullary bone. He found no incidence of root resorption, no loss of tooth vitality and no pocket formation.
Kole used this surgical technique for correction of some of dento-alveolar problems as:
Protruding of lower incisors: this procedure is indicated in most of cases but should be determined whether a mandibular or dento-alveolar retrusion. Buccally the cortiocotomy is performed between the incisors and canine then horizontal cut is made 1cm. below the incisors, lingual two vertical and one horizontal cut is made fig(1).
Distal displacement of a single tooth or group of teeth: correction necessitates a long period of treatment in adult patients fig(2) .
The retrusion of all six lower anterior teeth: after buccal and ligual corticotomy is perefrmed.
Alignment of rotated teeth.
Correction of spaced teeth: in maxillary and mandibular protrusion with diastemas between the t
Periodontally Accelerated Osteogenic Orthodontics with Piezoelectric Surgery...Abu-Hussein Muhamad
Piezosurgery has been applied in dentistry for many years. This paper reviews specifically the treatment applications that have been used in surgically assisted orthodontic treatment since the last decade. Periodontally Accelerated Osteogenic Orthodontics (PAOO) is a surgical technique which results in an increase in alveolar bone width, shorter treatment time, increase post-treatment stability, and decrease amount of apical root resorption. The aim of this case report is to compare the use of micro-motor and piezoelectric surgery unit during decortication in Periodontally Accelerated Osteogenic Orthodontics technique.

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.

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
8. RESECTIVE OSSEOUS SURGERY
8/34
defined as the procedure by which changes in the alveolar bone
can be accomplished to rid it of deformities induced by the
periodontal disease process or other related factors, such as
exostoses and tooth supra eruption. CARRAZA 10TH EDITION
Terms :
DEFINITIVE OSSEOUS SURGERY : establishes a positive
or normal parabolic osseous form
COMPROMISE OSSEOUS SURGERY: indicates an osseous
topography requiring extensive osseous removal that
would be detrimental to the long-term prognosis of the
tooth
9. OBJECTIVES
9/34
Elimination of periodontal pocket and creation of physiological
parabolic contour.
This contour will maintain physiologic gingival architecture.
Regeneration of periodontal apparatus destroyed by periodontal
disease.
Create environment suitable to restorative and prosthodontic
treatment.
10. EXAMINATION AND TREATMENT
PLANNING
10/34
Transgingival probing /sounding (EASLEY, 1967)
1. Osseous topography
2. Intrabony defects (one, two, or three wall
defects)
3. Furcation involvement (Class I, II, or III)
4. Root shape or form
Radiographs are important to locate the areas of bone loss
11. TERMINOLOGY OF OSSEOUS SURGERY
11/34
Tissue management
Procedures used to correct osseous defects have been classified in
two groups:
OSTEOPLASTY: defined as a plastic procedure by which
nonsupporting bone is reshaped to achieve a physiologic gingival
and osseous contour.
OSTECTOMY: is the plastic removal of radicular and
interradicular supporting bone to eliminate osseous deformities.
FRIEDMAN 1955
13. STEPS FOR RESECTIVE OSSEOUS
SURGERY
13/34
VERTICAL GROOVING
RADICULAR BLENDING
HORIZONTAL GROOVING
SCRIBING
GRADUALIZING INTERPROXIMAL BONE
14. OSTEOPLASTY:
14/34
It is a plastic procedure by which non supporting bone is reshaped
to achieve a physiological gingival and osseous contours.
INDICATIONS
Pocket elimination
Tori reduction
Intra bony defects adjacent to edentulous ridges
Incipient furcation involvement
Thick heavy ledges and exostoses
Shallow osseous craters
Small intra bony defects
15. 15/34
Osteoplasty includes the techniques of grooving or festooning
(ochsenbein, 1958) and radicular blending (carranza, 1984).
These grooves are carried to the line angles of adjacent
teeth.
Using a round no. 6, 8 or 10 bur in a high speed
handpiece with copious amounts of water, the grooves
are cut
19. OSTECTOMY
19/34
It is the plastic removal of radicular and interradicular supporting
bone to eliminate osseous deformities.
INDICATIONS
Sufficient bone remaining for establishing physiologic contours
without attachment compromise
No esthetic or anatomic limitations
Interdental craters
Intrabony defects not amenable to regeneration
Horizontal bone loss with irregular marginal bone height
Moderate to advanced furcation involvements and hemisepta.
20. CONTRAINDICATIONS
20/34
Areas of insufficient remaining attachment or where ostectomy
might unfavourably alter the prognosis of the adjacent teeth
Anatomic limitations (prominent external oblique ridge , zygomatic
arch)
Esthetic limitations (anteriorly , high smile line)
ADVANTAGES :
Predictable pocket elimination
Establishment of physiologic gingival and osseous architecture
Establishment of a favorable prosthetic environment
21. 21/34
Ostectomy is done by the technique of spheroiding or
parabolizing.
Parabolizing is the removal of supporting bone to produce a
positive gingival and osseous architecture.
This can be achieved by:
-Horizontal grooving
-Scribing
-Hand instrumentation
26. BASIC RULES OF OSSEOUS
SURGERY
26/34
Rule-1 A full-thickness mucoperiosteal flap should be raised.
Rule- 2a. The scalloping of the flap should anticipate the final
underlying osseous contour, which is more prominent anteriorly
and decreases posteriorly.
Rule -2b. The scalloping of the flap should reflect the patient’s
own healthy gingival architecture.
Rule-2c. The degree of tissue and bone scalloping is reduced, as
the interproximal area becomes broader as a result of bone loss.
27. 27/34
Rule-3. Osteoplasty generally precedes Ostectomy
Rule-4. Osseous resective surgery whenever possible should
result in a positive osseous architecture.
Rule-5. High-speed rotary instrumentation should never be used
adjacent to the teeth for fear of nicking and damaging the teeth
and should always be used with a generous spray.
Rule-6. The final bony contours should approximate the
expected healthy postoperative gingival form with no attempt to
improve upon it.
28. CONTRAINDICATIONS
28/34
Position of the external oblique line in the mandibular molar area and
maxillary sinus, which is very close to the osseous defect and root
proximity.
A periodontal pocket of more than 8mm exists after initial therapy.
The bottom of osseous defect extends apically against multiple tooth–
root trunks.
The deep intrabony defect is more than 3-4mm or the bottom of the
osseous defect is more than one half of the root length from the cemento
enamel junction.
Extended tooth mobility.
30. DISADVANTAGES
30/36
Attachment loss
Root exposure
Compromising esthetics
Strong possibility of hypersensitivity
Strong possibility of root surface caries
Possibility of phonetic impediment
31. FLAP PLACEMENT AND CLOSURE
31/34
Flap may be replaced to their original level to cover the new
bony margin or they may be apically positioned.
Replacing the flap in the areas that previously had pockets may
result initially in greater post operative pocket depth, although
a selective recession may diminish the depth over time.
Sutures should be placed with minimal tension to coadapt the
flaps, prevent their separation and maintain the position of the
flaps
33. CONCLUSION
33/34
The results from osseous resective surgery are technique sensitive. It
has limited use in treating cases with very deep intrabony or
hemiseptal defects, which should be treated with a different surgical
approach. If osseous resective surgery is used in advanced lesions, a
compromise in the amount of probing depth reduction should be
expected.
