摘要： 目的使用影像学手段分析种植义齿颈部牙槽骨丧失情况。方法观察27例患者共38颗种植体植入时、修复时和修复后3、6、12个月时的根尖片。结果种植体颈部牙槽骨于修复时平均丧失0.35mm,修复后3、6、12个月分别丧失0.57mm、0.67mm和1.01mm。上、下颌之间,埋植式和非埋植式之间,牙槽骨丧失量无显著性差异;修复时和修复后3个月ITI种植体牙槽骨丧失小于Replace Select种植体(P<0.01),修复后6、12个月无显著性差异。结论两种系统的种植体均获得良好的骨结合。ITI系统种植体颈部骨丧失小于Replace Select系统。埋植式或非埋植式对骨丧失无影响。

Abstract: Objective To analyze peri-implant alveolar bone loss with radiography. Methods 38 implants were inserted in 27 cases. The peri-implant alveolar bone was observed and measured with intraoral radiography at time of insertion, functional loading, and 3, 6, 12 months after functional loading. Results The mean peri-implant alveolar bone loss was 0.35 mm immediately after functional loading, 0.57 mm, 0.67 mm,1.01 mm at 3,6,12 months later. There was not significant difference of bone loss between maxilla and mandible, neither of submerged and non-submerged implants. ITI implants performed significantly less bone loss than Replace Select within 3 months after functional loading (P<0.01). Conclusion Osseointegration will successfully be obtained on implants involved. The peri-implant alveolar bone loss with ITI is less than that with Replace Select. The bone loss is not different between submerged and non-submerged implants.
