目的探讨影响后牙种植义齿边缘骨吸收的相关因素。方法选择2012年1月至2014年6月在郑州市中心医院口腔科行后牙区种植单冠修复的172例患者,共183颗ITI种植体,观察患者年龄、种植体长度、直径、位置、种植修复体冠根比例(CRR)及慢性牙周炎病史等因素对种植体周围边缘骨吸收的影响。结果对患者随访1~3年,种植体总生存率为100%;种植修复体CRR的平均值为(1.05±0.18)。在修复后第1年,MBL值显著高于其他时间段测量值,P<0.05;慢性牙周炎病史患者的MBL值相对较高,具有统计学差异(P<0.05)。结论种植义齿修复后一年内MBL显著,慢性牙周炎病史与MBL之间存在一定关联。
Objective To explore the factors that influence the bone resorption at the edge of implant denture. Methods A total of 172 ITI implants were implanted in the posterior teeth of the dental department of Zhengzhou Central Hospital from January 2012 to June 2014. A total of 183 ITI implants were selected. The age, implant length, diameter, location, The effects of implant coronal root ratio (CRR) and history of chronic periodontitis on the bone resorption around the peri-implant. Results The patients were followed up for 1 to 3 years. The overall survival rate was 100%. The mean CRR of implant prosthesis was (1.05 ± 0.18). In the first year after repair, the MBL value was significantly higher than the other time period measurements, P <0.05; MBL patients with a history of chronic periodontitis had a relatively high MBL value (P <0.05). Conclusions There is a significant correlation between MBL and MBL in the history of chronic periodontitis and one-year MBL after implant denture repair.
