Class III orthognathic surgical cases facilitated by accelerated osteogenic orthodontics: a preliminary report

Abstract

Objectives To describe a multidisciplinary treatment approach that includes corticotomy, orthodontic force and orthognathic surgery for the management of skeletal Class III surgical cases. The main advantage of the combined techniques is a reduction in treatment time for young adult patients. Method Accelerated Osteogenic Orthodontics (AOO) was delivered to three young adult patients during their pre-surgical orthodontic treatment. After aligning and levelling the dental arches, a piezosurgicalcorticotomy was performed to the buccal aspect of the alveolar bone. Bone graft materials were used to cover the decorticated area and soft tissue flaps were replaced. Results The mean time for extraction space closure was 5.4 ± 1.3 months and the mean time for pre-surgical orthodontic treatment was 12.0 ± 0.9 months. The average total treatment time was 20.4 ± 2.4 months. A pre-existing bony fenestration in the buccal cortex adjacent to the right lateral incisor root apex of Case 1 was corrected. Conclusion The facial aesthetics of three patients improved following multidisciplinary treatment. This approach may be an efficient method for the orthognathic patient who desires a reduced treatment time, but further clinical research is required.

Orthodontics Surgical Assistance (Piezosurgery®): Experimental Evidence According to Clinical Results

“…For this reason, a series of surgical techniques have been described in the literature, so as to be able to effectively reduce orthodontic treatment time and significantly reduce the number of complications [25][26][27][28][29][30][31]. These include osteogenic distraction, corticotomies, cortical incisions, piezoelectric osteotomy, decortication, ligament dislocation and distraction technique (MTDLD).…”
