摘要/Abstract

摘要： 目的： 探讨游离端与非游离端单颗种植体的垂直骨吸收量是否有差异。方法： 选择进行种植修复的牙缺失患者50例（50颗种植体）,根据牙位分为非游离端缺失组（A组）和游离端缺失组（B组）。一期植入直径4.1 mm、长度不等的种植体,术后3个月进行全瓷冠修复。应用CBCT测量修复后36个月的骨吸收量。采用SPSS 22.0软件包对数据进行统计学分析。结果： 随访期间,所有种植体无松动、脱落。A组远中骨吸收量为（0.288±0.183）mm,近中骨吸收量为（0.291±0.136）mm;B组远中骨吸收量为（0.562±0.201）mm,近中骨吸收量为（0.425±0.221）mm。A组平均骨吸收量为（0.289±0.144）mm,B组平均骨吸收量为（0.494±0.182）mm;B组远中骨吸收量显著多于近中骨吸收量（P<0.05）,B组平均骨吸收量显著多于A组（P<0.05）。结论： 游离端单颗种植体远中骨吸收量显著高于非游离端,提示游离端单颗种植体存在更高的骨吸收风险。

Abstract: PURPOSE: To investigate whether there is a difference in bone resorption between free-end and non-free-end single implant. METHODS: A total of 50 patients with tooth loss (50 implants) for implant restoration were selected. According to the tooth position, they were divided into non-free-end missing group (group A) and free-end missing group (group B). One-stage surgery was performed with eligible implants which were of different lengths and 4.1 mm in diameter. Single crown was placed after 3 months, Bone resorption was measured on CBCT after 36 months of follow-up. SPSS 22.0 software package was used for data analysis. RESULTS: There was no loosing or falling off of implants during the follow-up period. The distal bone resorption of group A was (0.288±0.183)mm, and the mesial bone resorption of group A was (0.291±0.136)mm, the distal bone resorption of group B was (0.562±0.201)mm, the mesial bone resorption of group B was (0.425±0.221)mm, the average bone resorption of group A was (0.289±0.144)mm, the average bone resorption of group B was (0.494±0.182)mm. Among them, the distal bone resorption of group B was significantly more than that of group A (P<0.05), and the average bone resorption of group B was significantly more than that of group A(P<0.05). CONCLUSIONS: The amount of bone resorption in the free end of a single implant is significantly higher than that of the non-free-end single implant, suggesting that the free-end single implant restoration has a higher risk of bone resorption.
