Introduction. Dental inclusion is an anomaly characterized by the retention of a tooth in the alveolar process, the eruption of which has been blocked by its position in the bone or an adjacent tooth. Orthodontic surgery offers surgical methods to aid orthodontic treatment in treating dental inclusion. Objective of the study. To evaluate the diagnostic features and treatment methods of orthodontic surgery for dental inclusion. Material and methods. Patient T.E., F/21 years old, presented at the dental clinic "Omni Dent" with aesthetic and functional complaints. The diagnosis- malocclusion class III Angle associated with the inclusion of tooth 23 was established through clinical and paraclinical examinations (OPG, TRG, CBCT, photographic examination, intraoral scanning). tooth 23, which had a horizontal position, had indications for odontectomy. Results. Orthodontic treatment was initiated using the fixed bracket system, to align the dental arch and create the necessary space for eventual implant-prosthetic restoration. Surgically, tooth 23 was extracted by incising and elevating the mucoperiosteal flap, drilling the cortical bone to expose the included tooth, dividing it and removing it sequentially. The created defect was filled with augmentation materials (Kolapol KP3LM) and fibrin membranes (A-PRF). After the osteointegration period (6 months), implantation followed. Conclusions. Dental inclusion is a frequently occurring dental eruption anomaly that creates aesthetic discomfort and functional disturbances. Orthodontic surgery methods aid orthodontic treatment. Extraction of the included tooth and replacement with a dental implant is often inevitable.
