磨牙区种植同期牙槽烤顶引导骨再生的临床研究

The clinical study of alveolar bone grafting in molar area

目的研究磨牙区种植同期牙槽悄顶引导骨再生的1年期效果。方法选取2017年8月至2019年7月在大连市口腔医院种植科就诊的55例患者,共植入58颗种植体,其中种植同期牙槽悄顶引导骨再生的为实验组,共29颗,种植同期未进行引导骨再生的为对照组,共29颗。比较两组留存率、边缘骨吸收、牙龈指数、探诊深度,结果用SPSS 20.0统计软件进行分析。结果对照组和实验组种植体留存率均达到100%;边缘骨吸收无显著性差异;实验组牙龈乳头指数优于对照组(P<0.05),实验组和对照组探诊深度、牙龈指数无统计学差异。结论磨牙区种植同期引导骨再生可以增加种植体和天然牙邻间骨高度,改善牙龈乳头充盈度。

Objective To study the one year clinical effect of guided bone regeneration(GBR)of implant placement in the molar sites.Methods 55 patients were selected from August 2017 to July 2019,58 implants were implanted,of which 29 were set as experimental with simultaneous implant placement and GBR,29 patients were selected as control group.The survival rate,marginal bone loss(MBL),gingival index(Gl)and probing depth(PD)were compared between the two groups.Results SPSS 20.0 was used to make statistics.Results The survival rate of implants in control group and experimental group was 100%;There was no significant differenee in bone absorption at the margin;The gingival papilla index of experimental group was better than that of the control group(P<0.05),and there was no statistical difference in GI and PD between the experimental group and the control group.Conclusion The simultaneous implant placement in the molar sites with GBR can increase the height of the implant and the adjacent bone of the natural teeth and improve the filling degree of the gingival papilla.
