骨水平种植体与软组织水平种植体应用于后牙区的临床效果比较

目的 评价Straumann种植系统的软组织水平种植体和骨水平种植体应用于后牙缺失区的临床效果.方法 选取接受后牙区单颗种植修复的108例患者,分别植入58颗Straumann软组织水平种植体和50颗骨水平种植体.随访2年,统计两组种植成功率、种植体周围骨吸收高度、牙周探诊软组织情况和患者的满意程度.结果 术后2年内软组织水平种植体周围骨呈递减式吸收,骨水平种植体周围骨缓慢均匀吸收,骨水平种植体骨高度优于软组织水平种植体.牙周探诊检查两组牙周软组织健康相当,患者反馈满意度差异无统计学意义.种植体成功率均为100％.结论 在后牙区,骨水平种植体周围骨吸收优于软组织水平种植体.

A comparative study of clinical effects between bone level implants and soft tissue level implants in posterior region

Objective To evaluate the clinical effects of Straumann bone level implants and soft tissue level implants in posterior region. Methods A hundred and eight cases of single posterior tooth loss were selected from patients treated at dental implant center,who were implanted with 58 Straumann soft tissue level implants and 50 bone level implants,respectively.The patients were followed up for 2 years and the success rate of implants,the marginal bone levels around implants,changes of soft tissues around implants by periodontal probing examination,and patient satisfaction were studied. Results Two years after implantation,alveolar bone around soft tissue level implants made decreasing resorption and alveolar bone around bone level implants did evenly and slowly.Observation and analysis on two kinds of implants showed that the level of bone resorption in bone level implants was better than that in soft tissue level implants.No difference was found in soft tissues around implants and patient satisfaction feedback between the two groups.The success rate of all the implantations in the 108 cases was 100%. Conclusions In posterior area,the level of bone resorption in bone level implants is superior to soft tissue level implants.
