This case report demonstrates sequential periodontic, orthodontic and prosthodontic treatment modalities to save and restore deep horizontally fractured maxillary central incisor. The location of fracture was deep in the mucosa which reveals less than 2 mm of tooth structure to receive the crown. The procedures like surgical crown lengthening, endodontic post placement, orthodontic forced eruption, core build-up and metal-ceramic crown restoration were sequentially performed to conserve the fractured tooth. Forced eruption is preferred to surgical removal of supporting alveolar bone, since forced eruption preserves the biologic width, maintains esthetics, and at the same time exposes sound tooth structure for the placement of restorative margins.
本病例报告展示了一系列牙周、正畸和修复治疗方法,以挽救并修复上颌中切牙水平深度折断的情况。骨折位置深及黏膜,剩余不到2毫米的牙体结构用于容纳牙冠。依次进行了外科牙冠延长术、根管桩置入、正畸牵引萌出、核桩修复和金属烤瓷冠修复等操作,以保留折断的牙齿。相较于手术去除支持性牙槽骨,牵引萌出更为可取,因为牵引萌出可保留生物学宽度、维持美观,同时暴露健康的牙体结构以放置修复边缘。
