This document compares and contrasts distraction osteogenesis (DO) and orthognathic surgery (OGS). Some key differences include:
- DO allows for larger advancements of bone (10+ mm) which are more stable, while OGS is generally not advised for advancements over 7 mm.
- OGS allows for multidirectional movements of bone segments while DO is limited and cannot perform impactions, setbacks, or compressions.
- Planning and surgical procedures are generally less complex for DO compared to OGS which may involve multiple segmented osteotomies.
- DO eliminates the need for bone grafting and surgical splints during surgery. Recovery is also typically less invasive than OGS.
Autogenous corticocancellous iliac bone graft in reconstruction of mandibular...Opi Akbar
This study evaluated the use of autogenous corticocancellous iliac bone grafts for reconstruction of mandibular defects in 37 patients between 1999-2006. Ameloblastoma was the most common reason for mandibular resection. Hemimandibulectomy was the most common surgery. A high graft take rate of 91.1% was achieved. The most common complication was infection in 27% of patients, which responded well to treatment. Donor site complications were minimal. The study concludes autogenous iliac bone graft is a good option for reconstruction of mandibular defects in environments where more advanced options are unavailable.

It discusses how surgical techniques and rehabilitation have improved results but adhesion formation remains a challenge. Various adjuncts are explored including growth factors, platelet rich plasma, stem cells, and gene therapy which show potential to aid faster healing with less adhesions. Ultrasound, magnetic fields, and rhynchophylline have also demonstrated positive impacts on tendon repair in animal studies. Continued research seeks safer and more effective ways to biologically manipulate the healing process at the cellular level.

Distraction osteogenesis is a technique that involves cutting bone and gradually separating the bone segments to stimulate new bone growth. It relies on prolonged, controlled distraction to expand soft tissue and bone volume simultaneously without disrupting blood supply. The process was discovered accidentally by Russian orthopedic surgeon Ilizarov in 1988. It has various applications including lengthening of bones like the mandible and advancing structures like the midface. The treatment involves phases like latency, distraction, consolidation and retention to achieve the desired correction.

Distraction osteogenesis is a technique used to regenerate bone by gradually separating a bone in two pieces. It works by placing tension stresses across the bone gap which stimulates new bone growth. It has been used to treat various craniofacial abnormalities and avoid problems with conventional surgery. The history of distraction osteogenesis dates back to 1905 but it was pioneered and expanded upon by Ilizarov in the 1950s for limb lengthening. It has since been adapted for use in the craniofacial region including the mandible, maxilla and midface.

Distraction osteogenesis /certified fixed orthodontic courses by Indian denta...Indian dental academy
Distraction osteogenesis is a surgical technique that involves gradually stretching bone and soft tissue by applying tension over time in order to reconstruct skeletal defects. It utilizes the body's natural healing process to generate new bone where it is needed. Some key advantages are that it causes little relapse, allows for larger movements than traditional bone grafts, can mold the new bone shape, and has lower morbidity. The technique was first developed in the early 1900s but was refined by Russian orthopedic surgeon Gavriel Ilizarov in the 1950s. It was later adapted for use in dental applications involving the mandible and maxilla.
This document provides a history of distraction osteogenesis. It began in 1905 with lengthening of long bones, was pioneered for the maxillofacial region by Ilizarov in the 1950s using gradual traction to regenerate bone, and was first applied to the human mandible by McCarthy in 1989. Since then, distraction techniques have been used increasingly as alternatives to orthognathic surgery, with applications to the maxilla beginning in the 1990s and advances in device design improving three-dimensional control and outcomes. The biology of distraction osteogenesis involves regeneration of new bone between segments separated by gradual traction applied during the distraction phase.
This document discusses distraction osteogenesis, a technique used to regenerate bone by gradually separating bone segments. It was introduced in 1951 by Ilizarov who used external fixation devices. The key steps involve cutting and separating the bone followed by slow distraction of 1mm per day which stimulates new bone formation. Both extraoral and intraoral devices are described. Applications include lengthening of the mandible for conditions like micrognathia. The process relies on stability of fixation, controlled distraction rate, and preservation of soft tissues. It allows reconstruction of craniofacial bones without growth factors.
Distraction osteogenesis is a biological process used to treat craniofacial deformities. It involves separating bone segments gradually through incremental traction to stimulate new bone formation. Historically, it has been used since the early 1900s to lengthen limbs, and was first applied to the craniofacial skeleton in the 1980s. The process involves osteotomy, latency, distraction, consolidation, and remodeling phases. Both internal and external devices can be used uni-directionally or multi-directionally. Factors like age, site of surgery, rate and rhythm of distraction influence outcomes. The orthodontist plays a key role in planning distraction vectors and post-treatment orthodontics.

This document presents a comparative study of functional outcomes between lateral locking plate fixation and dual plating for closed fractures of Schatzker's Grade V tibial condyles in adults. 40 patients with this injury were randomly assigned to either lateral locking plate fixation or dual plating. Patients were followed up to 6 months and evaluated based on range of motion, time to union, and functional scoring scales. Results found that dual plating provided greater stability but was associated with more soft tissue complications and longer surgery time compared to lateral locking plate fixation. Both approaches achieved high rates of fracture union and functional recovery of the knee.

This study evaluated the healing of mandibular ramus bone block grafts used for alveolar ridge augmentation before implant placement through clinical, histological, and histomorphometric analysis. Bone blocks were harvested from the mandibular ramus in 15 patients and grafted to maxillary defects. After 3-9 months of healing, implants were placed and bone samples were taken. Histological analysis found signs of active remodeling but also substantial amounts of non-vital bone and generally weak neo-vascularization, suggesting that most osteocytes in the grafted bone do not survive and neo-vascularization of non-vital grafted bone is difficult. The outcomes suggest grafted bone undergoes slow remodeling into new vital bone.
Orthognathic surgery is used to correct skeletal defects of the jaw and face. It involves cutting and repositioning the jaws, and is often done together with other procedures like rhinoplasty or genioplasty. The surgery is performed under general anesthesia, with the jaws wired together during the procedure and often released before the patient wakes. Patients then follow a liquid diet initially and have frequent checkups as they recover over weeks or months.
This document provides a critical review of long term relapse studies in orthodontic treatment. It discusses terminology related to post-orthodontic changes, different schools of thought on relapse, basic theories of relapse, and causative factors. It examines long term stability studies on various orthodontic treatments and changes in dentition, including extraction vs non-extraction approaches and treatments for anterior open bite. Factors discussed that influence relapse include craniofacial growth, dental development, soft tissue matrix, treatment time, and periodontal forces.
Orthognathic surgery is used to correct skeletal discrepancies of the jaw bones that cannot be addressed by orthodontics alone. It involves both pre-surgical orthodontics to position the teeth and surgical procedures on the mandible and/or maxilla. Common mandibular procedures include sagittal split osteotomy to move the mandible forwards or backwards and vertical subsigmoid osteotomy to push the mandible back. The main maxillary procedure is a Le Fort I osteotomy where the maxilla is freed and can be repositioned using a buccal incision approach. Both procedures aim to correct functional and aesthetic issues of the jaws and require postoperative orthodontics for detailed occlusion.

Condylar sag is defined as an immediate or late change in the position of the condyle in the glenoid fossa after orthognathic surgery, leading to an undesirable change in occlusion. It can occur after procedures like BSSO, IVRO, and Lefort I osteotomy. Risk factors include incorrect vectoring during condylar positioning and incomplete bone splits. Condylar sag is classified as central or peripheral, and can be diagnosed intraoperatively by examining changes in occlusion. Preventative measures include rigid fixation and intraoperative patient awakening to detect changes.

This document describes a technique for selectively intruding overerupted molars in adult patients using a combination of selective alveolar corticotomies and a modified full-coverage maxillary splint with nickel-titanium springs. Two case reports are presented where this approach successfully intruded overerupted maxillary molars within 2.5-4 months without side effects. The technique aims to take advantage of the regional acceleratory phenomenon caused by corticotomies to increase orthodontic treatment efficiency for adult patients who require molar intrusion.
This document provides an overview of Lefort I osteotomy, including:
- A brief history describing the development of maxillary osteotomy techniques.
- Anatomical considerations and the biologic basis for maxillary osteotomies, which have shown adequate blood supply can be maintained.
- Indications for Lefort I osteotomy include altering vertical dimension, anteroposterior movements, and surgical expansion of the maxilla.
- Types of Lefort I osteotomies are described, including classic, quadrangular, and segmental variations. Postoperative management and potential complications are also outlined.
Immediate implant placement following tooth extraction can help preserve alveolar bone and provide benefits like fewer treatment visits. However, it also carries risks like increased mucosal recession on the facial aspect due to normal bone resorption after extraction. For optimal esthetic outcomes with immediate implants, it is important to have adequate facial bone volume, perform bone grafting if needed, and consider the patient's gingival biotype and bone defect morphology. Careful case selection and experience with the technique are important to minimize esthetic complications.
The document discusses maxillary orthognathic procedures, including common dentofacial deformities involving the maxilla, diagnosis and treatment planning, surgical anatomy and approaches, types of mid-face osteotomies, and potential complications. It describes techniques for anterior and posterior segmental maxillary osteotomies, as well as total maxillary osteotomies including LeFort I, II, and III procedures. Complications addressed include vascular compromise, hemorrhage, and infection.

This document describes the fabrication and use of an acrylic guidance flange prosthesis for a patient who underwent a hemisection of the mandible due to ameloblastoma. Loss of mandibular continuity can cause deviation towards the surgical side and altered jaw movement. The prosthesis helped guide the mandible into the correct intercuspal position and re-educate the muscles. Within 3 weeks of using the prosthesis and undergoing physiotherapy exercises, the patient was able to achieve proper occlusion without assistance. Guidance prostheses can successfully restore function for patients with mandibular defects when combined with physiotherapy.

1) Maxillary advancement can be done with a device attached directly to the maxilla and cranial bones, or with a rigid frame fixed to the cranium from which a screw device advances the maxilla forward and downward.
2) Errors in maxillary or mandibular positioning can occur during surgery and be difficult to correct, such as the maxilla being placed too high or low in the vertical dimension.
3) "Condylar sag" describes problems where the condyle is not properly seated in the glenoid fossa after surgery, which can result in occlusal discrepancies if not addressed. Precise placement of the condyles during surgery is important for postoperative stability.

Surgical relapse /certified fixed orthodontic courses by Indian dental academy
1. INDIAN DENTAL ACADEMY
Leader in continuing dental education

2. INTRODUCTION
AJO-DO 1991
The advent of orthognathic surgery has given the practicing
orthodontist, in conjunction with the oral surgeon, the ability to
correct skeletal deformities that previously had to be treated by
orthodontic means alone. Often these orthodontic attempts to
camouflage the skeletal deformity were unsatisfactory, since they
required the introduction of severe dental compensations in an
attempt to accommodate to the poor skeletal relationships.
As orthognathic surgery has grown more sophisticated, it has
allowed the surgeon to address many deformities that were
previously untreatable. www.indiandentalacademy.com
3. However, the long-term stability of changes resulting from
these surgical procedures has been an area of major concern
since the early days of orthognathic surgery, because the final,
long-term result, both esthetic and functional, is directly related to
the degree of postsurgical stability.
Stability is a key goal of both orthodontic treatment and
orthognathic treatment; lack of stability is considered a
complication, particularly as relates to the surgical aspect of the
correction.
www.indiandentalacademy.com
4. REVIEW LITERATURE
PROFFIT AND WHITE (1970),AO,were among the first to
mention relapse after surgical-orthodontic therapy. They felt that
relapse could be avoided by concentrating on eliminating the
original causes contributing to the original malocclusion as much
as possible, and by not operating while patients are still growing.
KENT AND INDOUINA (1970) J. Louisiana Dent. Assoc
state that correction of the openbite deformity is one of the most
challenging problems. Openbite treated with the combined efforts
of surgeon and orthodontist should produce stable results in
certain cases; however, regression is seen because of the
influence of the tongue, enveloping muscles of the jaw, unusual
skeletal features, or bone pathology..
www.indiandentalacademy.com
5. POULTON AND WARE (1971),AJO, stated that, “Probably the
suprahyoid muscles, which have been lengthened, are the main
force contributing to the relapse.”
WICKWIRE ET. AL. (1972),JOS, noted the affect of the
mandibular osteotomy on tongue position. They felt that the
anterior and superior position of he hyoid bone after Class II
surgery of the mandible was viewed as another indication of
muscle tension, stating that “It appeared, then, that stability of the
surgical result would be associated in some way with the stability
of the hyoid position.”
www.indiandentalacademy.com
6. In 1973, MCNEILL, Trans. Eur. Orthod. Soc.,
Suggested three possible mechanisms for regression:
1.Distraction of the condyle from the glenoid fossa at the time of
Surgery.
2.Condylar distraction due to healing scar tissue around the
osteotomy site.
3.Posterior migration of the anterior mandibular segment in
response to tension of the attached muscles and soft tissues
during the fixation period.
STEINHAUSER,JOS, stated that “We think there is less relapse
tendency in the mandibular advancement when combined with
suprahyoid myotomy, but we cannot yet prove this.”
www.indiandentalacademy.com
7. POULTON AND WARE (1973),AJO, showed skeletal changes
during maxillomandibular fixation. They measured relapses of
50% to 80%, but improved their results by the use of a neck brace
and posterior interocclusal bite opening for several months after
surgery.
GUERNSEY(1974),OS, reported a retrospective study of six
cases. He also found relapse in the immediate postoperative
period and while the patients were still in intermaxillary fixation,
and suggested suprahyoid myotomy.
GOLDSPINK(1976),Bristol J. Wright Ltd.
Reported that skeletal muscles will adapt to a physiologic
stretching of 40% of their resting length after four weeks of stable
skeletal immobilization. www.indiandentalacademy.com
8. WOLFORD ET AL. (1978),OS, noted that the mandibular
advancement is more stable in low-angle cases and less stable in
highangle cases.
EPKER ET AL. (1978),OS, stated in 1978 that – “As a reliable
surgical principle, the greater the magnitude of advancement, the
greater will be the potential for relapse”.
BELL AND JACOBS (1979),AJO, pointed out the need for
possible maxillary surgery in conjunction with mandibular
advancement to allow for autorotation and decrease the tendency
for relapse.
www.indiandentalacademy.com
9. WORMS ET AL. (1980),AO, University of Minnesota, seven
factors that could contribute to regression:
1)Condyle displacement 2)Condyle resorption 3)Gnathological
errors
4)Fibrous union 5)Misdiagnosis 6)Differential treatment planning
7)Proportionality.
EPKER AND WESSBERG (1982),BJO, They conclude that dental
stabilization alone without control of the proximal segment of the
mandible results in the greatest likelihood of skeletal relapse
following surgical advancement. Prolonged skeletal stabilization
with control of the proximal segment of the mandible is suggested
as the only practical method currently available for assuring
maximum stability. www.indiandentalacademy.com
10. BLOOMQUIST (1983),AAO-AAOMS Clinical Congress.
Suggests a need to improve fixation at the osteotomy site,
advocating a single lag-screw at each osteotomy site to control
changes between the proximal and anterior segments.
PROFFIT, TURVEY, PHILIPS,1989,JOMFS. When maxilla is
moved upward, the postural position of the mandible alters in
concert with the new maxillary movement, and occlusal forces
tend to increase rather than decrease.(This controls any tendency
for maxilla to immediately relapse downward, and contributes to
the excellent stability of this surgical movement)
www.indiandentalacademy.com
11. MOORE AT AL,(1991),JOMFS, They found that the surgical
group with the heighest risk of condylar resorption is women 20-
30 yrs of age with high mandibular plane angles and preoperrative
TMD signs and symptoms.
SNOW AT AL(1991),IJAOOS, Studied post surgical mandibular
growth appeared to occur mainly in the vertical plane.
BAILEY, DUONG, PROFFIT(1998),IJAOOS, Surgical correction
of C-III problem is less stable than C-II correction in the short-term
post-surgically, it appears to be more stable long term.
www.indiandentalacademy.com
12. HARADA, SUMIDA, ENOMOTO, OMURA(2002), EJO, They
suggest that a combination of a Lefort-I and horse shoe
osteotomy is a useful technique reliable superior repositioning of
the maxilla. The post operative change in the maxilla using this
combination osteotomy is comparatively stable.
www.indiandentalacademy.com
13. Theories for relapse:
AJO-DO 1991
(1) stretching of the muscles of mastication and the suprahyoid
musculature,(2) condylar distraction during surgery,(3) upward
and forward rotation of the mandible, and (4) changes in rotational
position between the proximal and distal segments.
Simultaneously, various surgical techniques and postsurgical
therapies have been advocated to minimize relapse:
These are suprahyoid myotomy and cervical collars, which were
used in attempts to reduce muscle tension after surgery.
www.indiandentalacademy.com
14. Numerous fixation techniques to reduce
postsurgical relapse:
(1) upper- and lower-border wiring, (2) Steinmann pins to
stabilize the maxilla, (3) skeletal-wire fixation, and (4) rigid fixation.
Studies that examined independent mandibular advancements
and maxillary LeFort I procedures have indicated a strong
tendency toward reduced amounts of relapse when either
skeletal-wire fixation or rigid fixation is used.
www.indiandentalacademy.com
15. Factors necessary to achieve stability
(vanarsdaal)
Orthodontic considerations:
1) Proper diagnosis of patients who would most benefit from
combined therapy:
*In borderline situations
*In other cases surgery is clearly needed
www.indiandentalacademy.com
16. 2) Growth factors and the timing of the referral:
•For moderate and severe C-III mandibular exess pateints
•For mandibular deficiency patients
•Patients with excessive vertical growth ( C-I & C-II )
•For maxillary transverse deficiency patients
•Psycho social needs
•The timing of referral.
www.indiandentalacademy.com
18. Surgical considerations:
1) Treatment plan:
surgery in which jaw,
single or double jaw procedures,especially for open bite.
2) Design of osteotomy:
maintenance of blood supply and accomplishment of
objectives.
3) Type of fixation:
*dental skeletal, rigid, semirigid, or combination
*even with rigid osseous fixation, 13 of 50 mandibular
advancement patients had greater than 25% relapse.
www.indiandentalacademy.com
19. 4) Muscles of mastication and blood supply:
5) Supra hyoid muscle pull:
6) Type of mandibular rotation:
downward, backward moment is more stable than upward,
forward movement.
7) The stability decrease as the magnitude of surgical correction
increases, especially in the following:
* maxillary vertical deficiencies.
* mandibular horizontal deficiencies.
8) Stability of the condylar position:
9) Neuromuscular adaptation:
www.indiandentalacademy.com
20. Three principles that influence post-surgical
stability:
I) Stability is greatest when soft tissues are relaxed during
the surgery and least when they are stretched:
Moving maxilla up relaxes tissues, moving the mandible
forward stretches tissues, but rotating it upward posteriorly
and downward anteriorly decreases the amount of stretch.
least stable mandibular advancement:- are those that lengthen
the ramus and rotate the chin up.
most stable mandibular advancement:- rotate mandible in
opposite direction.
The least stable orthognathic surgical procedure is widening of
the maxilla that stretches the heavy, inelastic palatal mucosa.
www.indiandentalacademy.com
21. II) Neuromuscular adaptation is essential requirement for
stability:
Fortunately, most orthognathic procedures lead to good
neuromuscular adaptation.
Repositioning of the tongue to maintain airway dimensions,(I.e., a
change in tongue posture) occurs as an adaptation to changes
produced by mandibular osteotomy.
Neuromuscular adaptation does not occur when the
pterygomandibular sling is stretched during mandibular
osteotomy, as when the mandible is rotated to close an openbite.
www.indiandentalacademy.com
22. III) Neuromuscular adaptation affects muscular length, not
muscular orientation:
If the orientation of a muscle group such as the mandibular
elevators is changed, adaptation cannot be expected.
Successful mandibular advancement requires keeping the ramus
in an upright position rather than letting it incline forward as the
mandibular body is brought forward.
The same is true, in reverse, when the mandible is setback: a
major cause of instability appears to be the tendency at surgery to
push the ramus posteriorly when the chin is moved back.
www.indiandentalacademy.com
23. Post surgical stability – clinical success.
PROFFIT (1996) IJAODS
Stability after surgical repositioning of the jaws varies depending
on the direction of movement, the type of fixation used, and the
surgical technique employed, largely in that order of importance.
The various jaw movements possible at surgery were ranked in
order of stability and predictability.
www.indiandentalacademy.com
24. SURGICAL ORTHODONTIC TREATMENT:
A HIERACHY OF STABILITY IJAOOS,1996
MORE Maxilla up VERY STABLE
Mandible forward 90%
Chin any direction STABLE 80%
Maxilla asymmetry
STABLE Mx up + Mn forward STABLE
PREDICTABLE Mx forward + Mn back Rigid fix only
Mandible asymmetry
LESS Mn back
Mx down PROBLEMATIC
Mx wider
www.indiandentalacademy.com
25. The most stable orthognathic procedure is superior
repositioning of the maxilla, closely followed by mandibular
advancement in patients whom anterior facial height is mantained
or increased.
Stability of mandibuar advancement is influnced by the pattern
of rotation of the mandible as it is advanced. Rotating the
mandible so that anterior face height is decreased, the mandibular
angle decreases, the gonial angle tends tobe pulled forward. This
stretches soft tissues in that area, and stability is compromised.
(Then combined surgery is more stable)
Mandibular setback is often unstable, so is downward movement
of the maxilla, that creates downward-backward rotation of the
mandible.
(controlling the inclination of the ramus at surgery is key to
stability) www.indiandentalacademy.com
26. Prevention of Relapse in Surgical-Orthodontic
Treatment JCO 1986
Factors that affect the stability of combined orthodontic and
surgical treatment vary according to the specific dentofacial
deformity being corrected. However, there are usually four basic
stages of treatment.
There are four basic stages of treatment:
1) Pre-surgical orthodontic phase:-
In this teeth are positioned so that surgery can produce an
occlusion to be finished after surgery.www.indiandentalacademy.com
27. 2) Immediate pre-surgical treatment planning:-
it determines the exact magnitude of surgical correction and of
any adjunctive procedures such as genioplasty, chelioplasty, or
alar cinch.
3) Surgical procedure & intermaxillary fixation:-
4) Post-surgical orthodontic treatment:-
