Deep Bite Malocclusion

Study will be directed to evaluate the dentoalveolar changes following maxillary incisor intrusion using utility arch assisted with micro-osteoperforations in deep bite cases.

This prospective clinical trial aims to evaluate the efficacy of clear aligner therapy compared to two different treatment modalities - anterior bite turbos and reverse curve of Spee (RCOS) archwires - for the correction of dental deep bite cases. Deep bite malocclusion is characterized by excessive vertical overlap of the anterior teeth and often requires intrusion of anterior teeth and leveling of the curve of Spee. In this study, 27 patients aged 16-30 years with an overbite ≥5 mm and no significant skeletal discrepancies will be randomly assigned into three equal groups: Group 1 (RCOS archwire), Group 2 (anterior bite turbos), and Group 3 (clear aligners). Cone-beam computed tomography (CBCT) will be used to assess changes in overbite and alveolar bone height and thickness before and after treatment. The primary outcome is the efficacy of overbite correction, and the secondary outcome is the assessment of alveolar bone remodeling. The study will be conducted at the Department of Orthodontics, Faculty of Dental Medicine, Al-Azhar University (Assiut Branch), and has been approved by the institutional ethical committee.
