摘要
背景:目前,对种植体周骨吸收速度随时间的变化趋势判断尚缺乏临床实验数据支持。目的:观察种植体植入后周围牙槽骨吸收的情况,评价时间因素对种植体周围骨吸收的影响。方法:收集2003/2010接受种植义齿修复治疗病例的所有直接数字化全景片,筛选出其中可供分析的全景片,并将其分为种植后即刻,1,3,6和12个月片,对所有全景片进行测量,比较种植体植入后不同时间种植体周围骨吸收速度的差异性。结果与结论:种植体植入后1个月和6个月之间,3个月和6个月之间,1个月和12个月之间,3个月和12个月之间的种植体周骨吸收速度的差异有非常显著性意义(P<0.01)。提示种植体植入后1～3个月内种植体周围骨吸收最显著。
BACKGROUND：Currently,there are few clinical data about the speed of peri-implant bone resorption with different times.OBJECTIVE：To observe the bone resorption of alveolar around after transplanting implant,and to evaluate the effect of time factor on peri-implant bone resorption.METHODS：All the direct digital panoramic films of oral implant cases after surgery from 2003 to 2010 were collected.Panoramic films for analysis were divided into immediate pieces,1,3,6,12 months groups after implantation.All the panoramic films were measured.The speed of peri-implant bone resorption at different post-operation times was compared.RESULTS AND CONCLUSION：There was significant difference of the peri-implant bone resorption rate at different post-operation times from 1 to 6,3 to 6,1 to 12,3 to 12 months（P 0.01）.It is indicated that the maximal peri-implant bone resorption occurs at 1-3 months after implant surgeries.
