Accelerated osteogenic orthodontics technique: The CAOT Technique Case selection is a very important step; both the orthodontist and the periodontist should agree upon the need for corticotomy, treatment plan and the extent and location of the decortication cuts. National Center for Biotechnology InformationU. Treatment goals were planned around an ideally positioned maxillary central incisor in three planes of space.
A limited number of successful techniques is available for the treatment of maxillary arch constriction; these include surgically-assisted rapid palatal expansion SARPE and slow palatal expansion. The patient was seen every two weeks in order to assess the treatment progress and to advance the orthodontic tooth movement. Suya specified that most orthodontic corticotomt should be completed in the first three to four months after corticotomy and before fusion of the tooth-bone units orthodpntics 7 ].
No effect on the vitality of the pulps of the teeth in the area of corticotomy was reported [ 47 ]. Most of conventional orthodontic treatments require more than one year to complete.
Facilitate Eruption of Impacted Teeth Surgical traction of impacted teeth, especially the canines, is a frustrating and lengthy procedure. Treatment outcomes of orthodontic treatment, corticotomy-assisted orthodontic treatment, and anterior segmental osteotomy for bimaxillary dentoalveolar protrusion. It was first introduced in by Kole as a mean for rapid tooth movement. Some patients orthoodntics orthognathic surgery due to fear, cost, lifestyle or underlying health issues.
Treatment cprticotomy of orthodontic ortuodontics, corticotomy-assisted orthodontic treatment, and anterior segmental osteotomy for bimaxillary dentoalveolar protrusion.
It has been shown that corticotomy is efficient in reducing the treatment time to as little as one-fourth the time usually required for conventional orthodontics [ 17 ]. Adequate bio-absorbable grafting material is placed over the injured bone.
Mechanical and biological basics in orthodontic therapy.
Corticotomy-Assisted Orthodontic Treatment: Review
Complications and Side Effects Although CAOT may be considered a less-invasive procedure than osteotomy-assisted orthodontics or surgically assisted corticotmy expansion, there have still been several reports regarding adverse effects to the periodontium after corticotomy, ranging from no problems [ 84144 ] to slight interdental bone loss and loss of attached gingiva [ 45 ], to periodontal defects observed in cortictomy cases with short interdental distance [ 46 ].
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. Unfortunately, there is still no strong evidence for enhanced stability after CAOT in the literature.
Antibiotics can be mixed with bone graft.
Corticotomy facilitated orthodontics: Review of a technique
Rapid orthodontic decrowding with alveolar augmentation: Orthop Clin N Am. Corticotomy-facilitated orthodontic treatment was found to result in better retention compared to conventional orthodontic treatment [ 2428 ]. The goals of tooth movement in the maxillary arch included transverse expansion and anterior protraction and extrusion.
A reduced chance of root orthodonics [ 2526 ], less oral hygiene-related enamel decalcification and better patient cooperation and acceptance are possible advantages when lengthy orthodontic treatment is avoided. All idealized tooth movements, if performed with corticotimy orthodontics, would have pushed the tooth roots outside of the alveolar housing. This was also attributed to a rapid alveolar bone reaction [ 20 ]. Cortical perforation can be made at selective areas to increase blood supply to the graft material Fig.
Corticotomy was found to produce bone resorption around the moving teeth by day 21 after surgery and the area refilled with bone after 60 days. Suya reported corticotomy-assisted orthodontic treatment of adult Japanese patients. Patients with active periodontal orthodontixs or gingival recession are not good candidates for CAOT. Once the team knows the tooth movement goals, the surgeon and orthodontist assess whether or not the available orrthodontics can support orthodotics movement.
This theory of en bloc movement to enhance tooth movement prevailed in several subsequent reports [ 5 – 8 ]. He believed that the tooth movements were made by moving blocks of bone using the crowns of the teeth as handles.
Full thickness mucoperiosteal flap is reflected on both buccal and lingual aspects beyond the apices of corticotoym teeth if possible Fig. Hwang H, Lee K. The decorticated side is assumed to exhibit reduced resistance to expansion and faster tooth movement, making the effect of any bilateral expansion appliance unilateral.
Molar intrusion with a palatal arch.
In an animal study, Liou et al. The use of segmental corticotomy to enhance molar distalization. Bissada An evidence-based analysis of periodontally accelerated orthodontic and osteogenic techniques: Open in a separate window. Alterations in osseous crestal height following interdental osteotomies.
Author information Article notes Copyright and License information Disclaimer. A full thickness flap is reflected and selective alveolar decortication is performed coticotomy the form of decortication cuts and points up to 0.
Longitudinal study on the effect of early interceptive treatment in 4-year-old children with unilateral crossbite. Alveolar augmentation of labial and lingual cortical plates were used in an effort to enhance and strengthen the periodontium, reasoning that the addition of bone to alveolar housing of the teeth, using modern bone grafting techniques, ensures root coverage as the dental arch expanded.
After corticotomy, demineralization occurs in the alveolar bone and the remaining collagenous matrix of the bone is transported with the tooth during its movement. Any interdental papillary tissue remaining interproximally should be left in place. The new bone heals around the teeth as they move into the new position, creating increased post-orthodontic tooth and soft-tissue stability.
