Accelerated Osteogenic Orthodontics Technique: A 1-Stage Surgically Facilitated Rapid Orthodontic Technique With Alveolar Augmentation

PURPOSE Demineralization of a thin layer of bone over a root prominence after corticotomy surgery can optimize the response to applied orthodontic forces. This physiologic response is consistent with the regional acceleratory phenomenon process. When combined with alveolar augmentation, one is no longer strictly at the mercy of the original alveolar volume and osseous dehiscences, and fenestrations can be corrected over vital root surfaces. This is substantiated with computerized tomographic and histologic evaluations. Two case reports are presented that demonstrate the usefulness of the accelerated osteogenic orthodontics technique in de-crowding and space closing for the correction of dental malocclusions. MATERIALS AND METHODS Orthodontics is combined with full-thickness flap reflection, selective alveolar decortication, ostectomy, and bone grafting to accomplish complete orthodontic treatment. RESULTS Rapid tooth movement was demonstrated in both cases and stability up to 8 years of retention. CONCLUSION The accelerated osteogenic orthodontics technique provides for efficient and stable orthodontic tooth movement. Frequently, the teeth can be moved further in one third to one fourth the time required for traditional orthodontics alone. This is a physiologically based treatment consistent with a regional acceleratory phenomenon and maintaining an adequate blood supply is essential.

Periodontal Accelerated Osteogenic Orthodontics: A Description of the Surgical Technique

1 a z t g r b t w t t b e v p eriodontal accelerated osteogenic orthodontics PAOO) is a clinical procedure that combines selecive alveolar corticotomy, particulate bone grafting, nd the application of orthodontic forces. This proedure is theoretically based on the bone healing attern known as the regional acceleratory phenomnon (RAP). PAOO results in an increase in alveolar one width, shorter treatment time, increased postreatment stability, and decreased amount of apical oot resorption. The purpose of this article is to escribe the clinical surgical procedures that comrise the PAOO procedure.

Accelerating tooth movement: The case for corticotomy-induced orthodontics

4 Increased societal demands have led patients to request shorter orthodontic treatments, yet their expectations for outstanding final results remain high. One option for reducing treatment time is the dual-specialty in-office corticotomy-facilitated bone augmentation approach called the periodontally accelerated osteogenic orthodontics procedure. Periodontally accelerated osteogenic orthodontics treatment can often be completed in one third to one fourth of the time required for traditional orthodontic treatment. More importantly, a greater degree of movement can be achieved, reducing the need for extractions while providing increased periodontal support; this can provide orthodontists with a new population of adult and adolescent patients who otherwise might not seek needed orthodontic treatment. Periodontally accelerated osteogenic orthodontics treatment is appropriate for both adults and adolescents when most of the permanent teeth have erupted. Full treatment quickly resolves the entire scope of the patients treatment needs, including minor facial reshaping. In conjunction with traditional orthodontics, segmental issues such as forced eruptions of impacted teeth and molar intrusions can be rapidly corrected. Treatment decisions are based on considerations such as severity of the malocclusion, preexisting alveolar deficiencies, extraction vs nonextraction protocols, and patient expectations. Corticotomy surgery provides for a periodontal ligament-mediated acceleration in tooth movement as a result of a stimulated regional acceleratory phenomenon in conjunction with the proper morphologic situation of a thin layer of bone in the direction of movement. The induced increase in bone turnover

Mandibular irregularity index stability following alveolar corticotomy and grafting : a 10-year preliminary study

OBJECTIVE To evaluate mandibular irregularity index stability following orthodontic treatment facilitated by alveolar corticotomy and augmentation bone grafting (Cort+). MATERIALS AND METHODS The irregularity index of 121 orthodontically treated and 15 untreated patient study casts was analyzed at 5 years and 10 years. RESULTS Cort+ resulted in significantly lower mandibular irregularity index scores at both 5 years (1.5 mm vs 4.2 mm, P < .000) and 10 years (2.1 mm vs 4.1 mm, P < .000) compared with conventionally treated patients. CONCLUSIONS Unmatched samples advise caution with conclusions, but orthodontic therapy combined with Cort+ enhanced the stability of the postorthodontic mandibular irregularity index for at least 10 years in this preliminary study.
