Materials and Methods: 765 medical records of patients of UFRJ Orthodontics Clinic were analyzed for upper incisor trauma. 40 medical records of trauma patients with complete initial documentation were selected. Lateral cephalometric radiographs were extracted from the volumetric exams, models, photographs, and medical records were analyzed. Results: Labial incompetence, marked degree of overjet and protrusion and projection of the upper incisors, present in Class II skeletal patients, act as the main predisposing factors for the occurrence of dental traumatism. Conclusions: two-phase orthodontic treatment should be the focus of future studies aiming to evaluate its performance as a preventive measure in reducing dental trauma rates in these patients. Descriptors: Dental trauma, malocclusion, orthodontic treatment, upper incisors. ¹ Department of Pediatric Dentistry and Orthodontics, Federal University of Rio de Janeiro – UFRJ.
