    Abstract:
    INTRODUCTION: This article proposes an innovative and revolutionary diagnostic and therapeutic protocol for performing dentoalveolar osteotomies in office under local anaesthesia with piezoelectric surgery using a surgical acrylic guide produced through software-based planning. METHODS: The method was applied in the correction of crossbites, changing in the curve of Spee, incisal decompensations and dental ankylosis. Performing a preoperative CT with a special splint, optical scanning of the models and the subsequent planning with software has enabled us to produce a model with rapid prototyping with the design of the osteotomy on which the surgical guide was shaped, the use of the guide associated with piezoelectric surgery, allowed to perform surgery under local anaesthesia, with minimal invasiveness and high accuracy. RESULTS: Dentoalveolar immediate movements, with preservation of the roots of teeth involved, allow for rapid treatment of malocclusions which would be long and often difficult if not impossible to treat with orthodontics only. Dentoalveolar osteotomies associated to osteodistraction concepts, allow the orthodontist to achieve with accuracy the objectives required by the treatment plan. CONCLUSIONS: GSOS is a new method, which, utilizing 3D optical scanning images of models, software and piezoelectric surgery, allows to perform dentoalveolar movements which may be dangerous to the roots or for the periodontal support, with orthodontics only. It dramatically reduces total surgical-orthodontic treatment time, with obvious great patient satisfaction.
