Straumann种植系统7年临床应用回顾分析

7-year clinical application of Straumann implants

目的:评价Straumann种植体7年临床应用效果。方法:2000年7月-2006年12月,上海交通大学医学院附属第九人民医院口腔颅颌面种植科先后为2449例患者植入实心螺纹型穿龈Straumann种植体5532颗。患者的平均年龄为40.2岁(16～87岁)。平均骨愈合期为5.39个月(1.75～23.75个月)。其中局部义齿修复2640例,覆盖义齿修复52例,全颌固定义齿修复18例。患者于修复完成后6个月复诊,以后每年定期复查。复查内容包括临床检查和X线检查。结果:种植体脱落91颗,其中59颗在愈合期内,留存率达98.36%。结论:使用Straumann种植系统修复牙列缺失和缺损,长期预后良好。

PURPOSE： To evaluate 7-year clinical application of Straumann implant treatment. METHODS： 5532 nonsubmerged Straumann implants were placed from july 2000 to december 2006 at the department of implantology, Ninth People＇s Hospital, College of Stomatology, School of Medicine, Shanghai Jiao Tong University. The average age of 2449 patients was 40.2 years （16 to 87 years） and healing period was 5.39 months （1.75 to 23.75 months）. A total of 2710 prostheses were accomplished, including 2640 fixed partial prostheses, 52 implant supported overdentures and 18 implant supported full arch fixed protheses. Patients were recalled 6 months after restoration and later annual follow-up. Clinical and X-ray examinations were performed during the follow-up period. RESULTS： Among the 91 failed implants, 59 implants were failed in healing period and considered early failures. The survival rate was 98.36%. CONCLUSION： Prosthetic restoration of partially edentulous and edentulous patients with the Straumann implant system can be described as a reliable and efficient therapy in the long term.
