Abstract：
OBJECTIVE: To evaluate the effet of one-time one-abutment placement on peri-implant tissues.
METHODS: Thirty-five patients with single posterior loss were collected, who received definitive abutment at the moment of implant placement. One day and after 1 year of implant loading, radiographic assessment of marginal bone level changes and clinical status of peri-implant soft tissues were conducted. Plaque index, pocket depth as well as sulcus bleeding index were assessed.
RESULTS: During 1 year follow-up period after loading, no implant failure was observed. The mean marginal bone loss of implants were (0.225±0.113) mm mesially and (0.439±0.123) mm distally. Standard periodontal probes were used to measure plaque index, probing depth, and gingival crevicular bleeding index immediately after repair and 1 year later.
CONCLUSIONS: In the posterior region, one-time one-abutment placement may better protect peri-implant tissues as an ideal treatment protocol.

摘要：
目的：评价一次性一次性基牙放置对种植体周围组织的影响。
方法：收集35例单后部丢失患者，在植入时接受了确定的基台。植入物装载一天和一年后，对种植体周围软组织的边缘骨水平变化和临床状况进行影像学评估.斑块指数,评估口袋深度和沟出血指数。
结果：在加载后的1年随访期间，未观察到植入失败.植入物的平均边缘骨丢失为（0.225±0.113）mm，远端为（0.439±0.123）mm。使用标准牙周探针测量菌斑指数，探测深度,修复后即刻和1年后的龈沟出血指数。
结论：在后部区域，作为理想的治疗方案,一次性一次性基牙放置可以更好地保护种植体周围组织.
