即刻种植的临床探讨

目的：报告拔牙后即刻种植的临床结果并对即刻种植的处理方法进行探讨。方法：拔除患牙，清创拔牙窝后，采用Branemark种植系统的操作方法，在Ⅰ期手术，将Branemark种植体即刻植入患者颌骨，酌情植入自体骨或异体骨，必要时加盖生物膜；4～6个月后，进行Ⅱ期手术，再经1～2周后，用目定修复体修复。结果：138颗即刻种植的Branemark种植体中，上颌76颗，下颌62颗，有4颗种植体失败，观察最长60个月，最短36个月，种植体存留率为96．4％。结论：即刻种植初步临床结果是满意的，其长期效果有待进一步的观察。

Clinical evaluation of immediate placement of dental implant

Objective:To report the clinical outcome of immediate placement of dental implants at the fresh extracted sites and evaluate the clinical methods of immediate placement.Methods:Clean the sockets after teeth extraction,and immediately put Branemark implants into jaw bones by the protocol.Bone graft with membrane cover is necessary in the cases with bone defects.4 to 6 months later,second stage surgery was done and fixed implant_supported bridge or crown was completed in another 2 weeks.Results:138 implants,76 in maxilla,62 in mandibles,were immediately placed into the jaw bones and haved been followed up for 36 to 60 months.The 3_year survival rate was 97.1%.Conclusion:The shor_term clinical results were satisfactory and the long_term outcome needs more observation.
