摘要
目的比较不同磨耗程度的患者后牙区种植义齿的短期临床疗效。方法选取2009年1月至2013年12月中国医科大学附属口腔医院种植中心收治的后牙部分缺失行种植义齿修复的患者469例（平均年龄50.9岁）,根据天然牙磨耗程度分为3组,其中非磨耗组201例（457枚种植体）、轻度磨耗组163例（289枚种植体）、重度磨耗组105例（235枚种植体）。种植术后随访6~72个月。比较分析3组病例的种植体5年累积存留率、种植体周围骨吸收情况及修复后并发症发生情况。结果 3组病例均无种植体脱落,种植体5年累积存留率均为100%;3组病例在修复后3个月、6个月、1年和2年的种植体周围骨吸收量差异无统计学意义（P〉0.05）;3组病例修复后的修复体崩瓷、种植体周围炎、食物嵌塞、修复体松动及邻接不良等并发症的发生率比较,差异均无统计学意义（均P〉0.05）。结论在短期时间内轻度磨耗及重度磨耗患者后牙区种植义齿修复均能获得良好的临床疗效,长期效果有待于进一步观察。
Objective To compare the short-term clinical effect of different degrees of wear in the posterior area of the implant denture.Methods From January 2009 to December 2013,469 patients（the average age was 50.9）with partial loss of posterior teeth were followed up for 6- 72 months. According to the degree of wear of natural teeth,they were divided into three groups,the non-wear group of 201 cases（457 implants）,163 cases in mild-wear group（289 implants）,105 cases in severe-wear group（235 implants）. The five-year cumulative survival rates of implants in the three groups were counted and the numerical values of bone resorption around the implants were measured.Results Three groups of patients had no implant loss;the 5-year retention rate was 100%;there was no significant difference in bone resorption at the end of 3 months,6 months,1 year and 2 years after the repair（P〉 0.05）;there was no significant difference in the incidence of postoperative complications（P 〉0.05）.Conclusion In short time,the patients with mild wear and severe wear can have good clinical effect,whereas long-term effect need to be followed up.
