口腔种植体边缘骨吸收的临床疗效评价

Clinical Evaluation of Dental Marginal Bone Resorption of Oral Implant

目的：观察口腔种植牙修复牙列缺损的临床应用效果。方法：收集2009年1月-2014年1月种植义齿修复牙列缺损47例患者,共Anthogyr系统94颗种植体。随访3-36个月,均对其在植入后即刻、3个月、6个月、12个月、（〉12）个月拍摄口腔曲面断层片,测量种植体周围骨吸收水平,并运用SPSS17.0进行统计分析。结果：种植体不同时间段骨吸收量之间有统计学差异;种植体植入后3个月与6个月之间,6个月与（〉12）个月之间,12个月与（〉12）个月之间的种植体周围骨吸收量有非常显著性意义（P〈0.05）。结论：种植体植入6个月时周围骨吸收量最大。

Objective： To observe the clinical effect of oral implant restoration of dentition defect. Methods： 47 ca- ses of patients with a total of 94 Anthogyr implants were collected from 2009 January to 2014 January. The follow-up was 3--36 months. The patients were taken oral panoramic tomography after immediately implantation, 3 months, 6 months andl2 months implantation, and measured the bone resorption. Results： There was statistical significance in the bone resorption between different period of time after implantation. Between the implants after 3months and 6 months,between 6 months and （〉12） months, between 12 months and （〉12） months, peri--im- plant bone absorption was statistically significant（P〈0.05）. Conclusion： After implant surgery for sixth months, bone resorption around implants was the maximum.
