BEGO种植体非埋入式与埋入式愈合疗效的对比研究

Comparison of applying the non-submerged and submerged osseointegrated BEGO dental implants

目的:比较Bego种植体非埋入式术式与埋入式术式的疗效差别。方法:以79名后牙区牙列缺损种植修复患者为研究对象,共植入93颗种植体。按照植入时的扭矩分组,<20 N.cm者为A组(空白对照组),采用常规埋入式术式愈合;>20 N.cm者随机分配到B组(埋入术式组)和C组(非埋入术式组),在修复前用种植体稳定性测量仪测试种植体的ISQ值(共振频率分析)。结果:埋入术式组和非埋入术式组在修复前测量的ISQ值差异无统计学意义(P>0.05)。在完成修复12月的观察期内93颗种植体均使用良好。结论:骨水平种植体在植入扭矩满足要求的情况下,非埋入式术式缩短了疗程,减少创伤,是理想的选择方案。

Objective：To compare the results of non-submerged surgery with submerged surgery on BEGO implant system.Methods：Ninety-three BEGO implants were used to replace the missed posterior teeth of 79 patients.Three groups were divided based on the insertion torque value of the implants.The value was smaller than 20 N.cm and that would belong to group A as the controlled group.The rest cases were assigned to group B and group C randomly,by using submerged and non-submerged surgery respectively.Resonance frequency analy-sis measurements were used to evaluate the implant stability of group B and C before restoration.Results：There was no statistically significant difference in the ISQ value between the group B and C（ P〉0.05）.All implants were in good condition after 12 months followed-up.Conclusion：Non-submerged surgery simplifies the treatment procedure and it could be a good choice when the insertion torque value of the implants is acceptable.
