A dentoalveolar fracture requires thorough clinical and radiographic examination for an accurate diagnosis to guide appropriate treatment. Dentoalveolar fractures can be classified into the following 4 groups: (1) crown/root fractures, (2) luxation/displacement of teeth, (3) avulsion, and (4) alveolar fractures. Treatment can be divided into nonrigid fixation (splinting with wires and composite) and/or rigid fixation (Erich arch bars, Risdon cable wires) depending on the extent of dentoalveolar fractures. Special considerations must be made for primary teeth and mixed dentition to avoid injuring tooth buds and arising permanent dentition.
牙槽突骨折需要进行彻底的临床和影像学检查,以做出准确的诊断并指导适当的治疗。牙槽突骨折可分为以下 4 组:(1)冠根折,(2)牙齿脱位/移位,(3)牙撕脱,和(4)牙槽突骨折。根据牙槽突骨折的程度,治疗可分为非刚性固定(用金属丝和复合树脂进行夹板固定)和/或刚性固定(埃里希弓丝、里森电缆丝)。对于乳牙和混合牙列,必须特别注意,以避免损伤牙胚和引起恒牙列的问题。
