Traumatic injuries to the maxillary anterior region may combine tooth displacement, pulpal damage and fracture of the supporting alveolar process. This case report describes the interdisciplinary rehabilitation of a 36-year-old woman following a road traffic accident. Computed tomography confirmed fracture of the alveolar process and lateral displacement of the root of tooth 11, with the apex trapped outside the alveolus. The crown was displaced palatally. Tooth 11 was unlocked, repositioned into its socket and stabilized with a 0.9 mm stainless steel orthodontic ligature wire semi-rigid splint for four weeks. Subsequent sensibility testing showed no response from tooth 11, whereas the adjacent maxillary anterior teeth remained responsive. With radiographic periodontal ligament widening and external resorption, the diagnosis was pulp necrosis with asymptomatic apical periodontitis in tooth 11. Root canal treatment was completed in tooth 11. Transillumination later revealed crack lines in the same tooth, and a full ceramic crown was planned. Tooth 21 remained vital and received a ceramic veneer with mesial proximal wrap and incisal overlap to address the midline diastema. Adhesive cementation produced a harmonious two-unit restoration while preserving tooth structure in the unaffected left central incisor.
