Piezoelectric Decortication Applied in Periodontally Accelerated Osteogenic Orthodontics

Abstract Our aim was to evaluate the application of piezoelectric decortication in periodontally accelerated osteogenic orthodontics (PAOO). One hundred fifty-six patients with severe skeletal malocclusions were enrolled in this study. Ultrasonic decortications were performed in 187 labial or lingual PAOO of the maxillary and mandibular anterior teeth. Orthodontic decompensation started from the fifth day after operation. All patients healed uneventfully and no severe periodontic complications were recorded. Rapid teeth movement and relatively short treatment duration were realized. Alveolar fenestration and bony dehiscence was successfully addressed. With physical and mechanical properties of absence of macrovibration, ease of use and control, piezosurgery showed its great values in PAOO.
