Abstract：
OBJECTIVE: The aim of the present study was to evaluate clinical and radiographic outcomes of implants placed in alveolar sockets treated by means of alveolar ridge preservation after 10 years of follow-up.
METHODS: Eleven patients treated with 11 implants placed after alveolar ridge preservation using bovine-derived xenograft particles and collagen membrane were selected. Full-mouth plaque score, full-mouth bleeding score, probing depth at four sites per implant, and radiographic marginal bone level at mesial and distal aspects for each implant were recorded at baseline and after 10 years of follow-up. The primary outcome was the radiographic marginal bone loss. The marginal bone loss was considered as the difference between marginal bone level at baseline and after 10 years of observation time.
RESULTS: After 10 years of follow-up, full-mouth plaque score increased significantly (P < .05), while no statistically significant differences were found in the change in full-mouth bleeding score (P ≥ .05). At the 10-year observation period, a significant increase in probing depth was observed at all sites (P < .05), except at the mesial aspects (P ≥ .05). Radiographic marginal bone loss was 1.1 ± 0.1 mm and 1.0 ± 0.1 mm at mesial and distal sites, respectively.
CONCLUSIONS: Whitin the limitations of the present study, implants placed in post-extraction sockets treated with alveolar ridge preservation yielded stable clinical and radiographic results after 10 years of follow-up.

摘要：
目的：本研究的目的是评估10年随访后，通过牙槽脊保留（ARP）方法将植入物放置在牙槽槽内的临床和影像学结果。
方法：选择11例患者，在使用牛来源的异种移植颗粒和胶原膜的ARP后放置11个植入物。全口菌斑评分（FMPS），全口出血评分（FMBS），在基线和10年随访后,我们记录了每个植入物4个部位的探测深度(PD)以及每个植入物中和远端的影像学边缘骨水平(MBL).主要结果是放射学边缘骨丢失（mBL）。mBL被认为是基线和10年观察时间后MBL之间的差异。
结果：经过10年的随访，FMPS显著升高(P>0.05),FMBS变化差异无统计学意义(P<0.05)。经过10年的观察期,在所有部位观察到PD的显着增加（P>0.05），除了内侧方面（P<0.05）。放射学边缘骨丢失（mBL）为1.1±0.1mm和1.0±0.1mm，分别。
结论：鉴于本研究的局限性，经10年随访后,将植入物置入经ARP治疗的拔牙腔内可获得稳定的临床和影像学结果.
