Dental traumas involve anterior teeth, affecting both function and aesthetics of children and young adults of different ages in different dental specialties. The teeth most frequently involved are the maxillary central incisors, lateral incisors and mandibular central incisors. The aim of this work is to present a clinical case of injury involving bone block fracture. After the accident, the patient underwent clinical examination, which revealed block fracture of dental elements 42, 41, 31, 32 and avulsion of 33 with laceration of the gingival and mucosal tissue. Radiographic results revealed horizontal fracture of the jawbone, tooth avulsion of its wells in the block and several bone fragments. Patient underwent immediate surgery using emergency containment with micro-screws, and suture was removed seven days after. Monitoring was performed at 14, 21 and 28 days and endodontic treatment of teeth 31, 32, 41 and 42 was performed 3 months after. All procedures were successful.
