如果没有适当的干预，压碎的牙槽突骨折可能会导致受影响的硬组织和软组织发生显著的尺寸变化，从而导致创伤后骨增强和牙种植体植入的困难情况。我们在此提出的情况下，立即引导骨再生（GBR）的上颌前牙槽突粉碎性骨折。在医院就诊后不久，仅使用异种移植材料和创伤部位的骨碎片对3名患者进行了引导骨再生，没有额外的供体部位。在植骨部位使用可吸收胶原膜，如果预期有显著骨丢失，也使用钛网。GBR后6个月的影像学评价证实，所有3例病例的牙槽骨均得到充分保存，这是种植体植入的临床要求。对两名患者进行了牙种植体安装，在放置后的随访中没有发现具体的发现。在这种方法中，不需要额外的骨收集手术部位，并且可以减少植入物放置前的手术步骤数量。同时，这种即时干预可以有效地减少上颌骨前部损伤后牙槽嵴的萎缩。
Without a proper intervention, a crushed alveolar process fracture can cause significant dimensional changes on affected hard and soft tissue that lead to difficult circumstances for post traumatic bone augmentation and dental implant placement. We present herein the cases of immediate guided bone regeneration (GBR) for the maxillary anterior alveolar process with comminuted fracture. Shortly after the hospital visit, guided bone regeneration was conducted for three patients using only xenograft material and bone fragments from traumatic site, without an additional donor site. Resorbable collagen membrane was used on the bone graft site, and titanium mesh was also used if significant bone loss were expected. Radiographic evaluation 6 months after GBR confirmed that all three cases had sufficiently preserved alveolar bone which is clinically required for implant placement. Dental implant installation was carried out for two patients and no specific findings were noted in follow-up after the placement. In this method, additional operation sites for bone collection are not necessary and the number of surgical steps before implant placement can be reduced. Furthermore, this immediate intervention can effectively minimize the alveolar ridge shrinkage of anterior maxilla after injury.
