Fracture of the alveolar process is a common injury. In some cases, traditional fixation may not be possible. The teeth needed for splinting or mandibulo-maxillary fixation may be missing. The fracture line and soft tissue injury may jeopardize the blood supply of the broken bone. In these extreme and rare situations, the best rehabilitation is needed to avoid the loss of hard and soft tissues, and a secondary reconstruction is required. Between January 2003 and December 2006, of 468 cranio-facial trauma patients studied, alveolar process fracture was reported in 28 (6%) cases. In six (1%) cases, the anatomy of the fracture lines, and the position and number of the remaining teeth made splinting and mandibulo-maxillary fixation impossible. Patients were treated with a transgingival lag-screw (TLS) osteosynthesis. All patients healed well with no complications. There was no bone or tooth loss in the surgical area, and broken fragments were not absorbed. The TLS technique is recommended for alveolar fractures when the blood supply is jeopardized and dental splinting or mandibulo-maxillary fixation is not possible. There is no need for flap reflection.
牙槽突骨折是一种常见的损伤。在某些情况下，传统的固定可能是不可能的。用于夹板固定或颌骨固定的牙齿可能缺失。骨折线和软组织损伤可能危及骨折骨的血液供应。在这些极端和罕见的情况下，需要最好的康复治疗，以避免硬组织和软组织的丧失，并需要进行二次重建。在 2003 年 1 月至 2006 年 12 月期间，在研究的 468 例颅面外伤患者中，有 28 例（6%）报告牙槽突骨折。在 6 例（1%）患者中，骨折线的解剖结构以及剩余牙齿的位置和数量使得夹板固定和颌骨固定变得不可能。这些患者接受了经牙龈拉钉（TLS）骨内固定术治疗。所有患者均愈合良好，无并发症。手术区域无骨或牙齿丢失，骨折碎片未被吸收。当血供受到威胁且无法进行牙夹板固定或颌骨固定时，TLS 技术推荐用于牙槽突骨折。不需要进行皮瓣翻转。
