目的：拔牙后会出现软硬组织改变，影响种植体的植入。材料和方法：研究对象为2017年1月1日至2018年1月1日在单颗后牙保存牙槽骨的患者，采用L保存牙槽骨、L富含血小板纤维蛋白复合异种骨和单纯异种骨移植3种方法保存牙槽骨。记录手术前和术后6个月的临床和X线测量，以确定水平和垂直牙槽骨吸收。结果：本研究共纳入45例患者。所有手术均顺利完成，无术中并发症发生。L-PRF组的水平和垂直方向的骨吸收显著增加。L-PRF复合异种骨移植组的垂直和水平骨吸收均小于单纯异种骨移植组。在术后疼痛和创面愈合方面，差异有统计学意义，尤其是单纯异种骨移植组，疼痛评分更高，伤口愈合延迟。结论：在本回顾性研究的限制范围内，单独使用异种骨或L-PRF联合异种骨进行牙槽骨保存操作显著限制了骨吸收。(C)2019年美国口腔颌面外科医生协会
Purpose: The extraction of a tooth is followed by hard and soft tissue changes that can compromise implant placement. The aim of the present retrospective study was to compare the clinical and radiographic outcomes of different ridge preservation procedures based on the use of leukocyte and platelet-rich fibrin (L-PRF).Materials and Methods: The study population consisted of all patients who had undergone surgery from January 1, 2017 to January 1, 2018 for alveolar ridge preservation on single posterior teeth using 3 clinical protocols: L-PRF alone, L-PRF mixed with a bone xenograft, and bone xenograft alone. Clinical and radiographic measures were recorded preoperatively and at 6 months postoperatively to determine the horizontal and vertical ridge resorption.Results: A total of 45 patients were included in the present study. All the surgeries were performed successfully, and no intraoperative complications developed. The L-PRF group experienced significantly greater horizontal and vertical bone resorption. The L-PRF plus bone xenograft group had less vertical and horizontal bone resorption than the bone xenograft alone group. Statistically significant differences in postoperative pain and wound healing were observed, with the bone xenograft alone group, in particular, having higher values for pain and experiencing delayed wound healing.Conclusions: Within the limitations of the present retrospective study, the use of a bone xenograft alone or L-PRF combined with a bone xenograft to perform alveolar ridge preservation procedures significantly limited bone resorption.
