Learn more about interdisciplinary treatment planning for corticotomy-facilitated orthodontics and read about a real-world case. Increased societal demands have led patients to request shorter orthodontic is the dual-specialty in-office corticotomy-facilitated bone augmentation approach.

Post-surgical crestal bone loss and recession may occur. Therefore, only the buccal maxilla required segmental ortjodontics and bone augmentation. Orthodontic treatment acceleration with corticotomy-assisted exposure of palatally impacted canines.
CAOT was also used to achieve molar distalization.
Corticotomy facilitated orthodontics: Review of a technique
Corticotomy surgery initiates and potentiates normal healing process Regional Acceleratory Phenomena Wilcko et al. Published online Aug Effects on the periodontium following corticotomy-facilitated orthodontics: Huthig Buch Verlag; Growth is an almost insignificant factor in adults compared to children, and there is increasing chance that hyalinization will occur during treatment [ 2 ].
How is tooth movement with corticotomy facilitated orthodontics differing from tooth movement with conventional orthodontic treatment? These considerations make orthodontic treatment of adults different and challenging as well as necessitate special concepts and procedures, such as the use of invisible appliances, shorter periods of corticotojy, the use of lighter forces and more precise clrticotomy movements.
The matrix then remineralizes after the orthodontic movement. Spontaneous eruption was completed in three months without any orthodontic traction Figs.
Any interdental papillary tissue remaining interproximally should be left in place. Modeling of trabecular bone and lamina dura following selective alveolar decortication in rats. After performing segmental corticotomy around the molars, the anchorage value and resistance of the molars to distal movement were effectively reduced without the use of any extra anterior anchorage devices [ 42 ]. However, further randomized testing in humans is still needed to confirm the claimed advantages of this technique and to evaluate the long term effects.
National Center for Biotechnology InformationU. Corticotomy facilitated orthodontics advocated for comprehensive fixed orthodontic appliances in conjunction with full thickness flaps and labial and lingual corticotomies around cortictomy to be moved.
This technique is similar to conventional corticotomy except that selective decortication in the form of lines and points is performed over all of the teeth that are to be moved. Non-extraction therapy is usually used to resolve mild to moderate crowding and usually results in proclination of the incisors.

Corticotomy-Facilitated Orthodontics and Goal-Oriented Treatment Planning – Spear Education
Post-treatment intra-oral photographs of the same patient seen in Fig. Comparison of corticotomy-facilitated vs standard tooth-movement techniques in dogs with miniscrews as anchor units. Pre-treatment panoramic radiograph of a female patient showing an impacted upper left second premolar.
Controlled clinical and histological studies are needed to understand the biology of tooth movement with this procedure, the effect on teeth and bone, post-retention stability, measuring the volume of mature bone formation, and determining the status of the periodontium and roots after treatment. Mechanical and biological basics in orthodontic therapy.
Thanks to new developments in interdisciplinary dentistry, we can now offer exciting and innovative treatment options for our patients.
An evidence-based analysis of periodontally accelerated orthodontic and osteogenic techniques: Post treatment panoramic radiograph of the same patient in figure 2, showing the fully erupted second premolar after CAE, extraction of the adjacent first premolar and fixed orthodontic treatment.
Am J Orthod Dentofacial Orthop.
Tisssue responses in corticotomy- and osteotomy-assisted tooth movements in rats: Conclusion — PAOO is relatively new procedure; only few cases were reported in the literature. Outstanding results and extreme patient satisfaction with corticotomy procedures were reported. Large bodily tooth movements were initiated immediately following a selective alveolar corticotomy and bone augmentation procedure, allowing the alveolus and teeth to remodel to the desired new position during the period of high bone turnover and subsequent healing.
Acceleration of orthodontic tooth movement by alveolar corticotomy in the dog. St Louis Univ; Rapid orthodontics with alveolar reshaping: Hosl E, Baldauf A, editors. Accelerated orthodontics with alveolar reshaping. Scand J Dent Res. CAOT was used in the treatment of bimaxillary protrusion as an adjunct to manipulate skeletal anchorage without any adverse side effects in only one-third of the regular treatment time [ 41 ].
Bissada An evidence-based analysis of periodontally accelerated orthodontic and osteogenic techniques: J Oral Maxillofac Surg. In addition, active and extensive bone remodeling around the moved tooth was shown. Introduction Dental arch crowding is one of the most common form of malocclusion. This accelerated remodeling is influenced by bone density and the hyalinization of the periodontal ligament PDL [ 11 – 14 ]. Large tooth movements occurred efficiently within the weeks following the surgery.
Several clinical applications for CAOT have been reported. The rate and the type of orthodontic tooth movement is influenced by bone turnover in a rat model.
Performing corticotomy on only the constricted side helps to overcome these unnecessary side effects. 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. Wilcko explained the concept of reversible osteopenia in a study of five patients using computed tomographic imaging [ 17 ]. Once the team knows the tooth movement goals, the surgeon and orthodontist assess whether or not the available bone can support such movement.
