种植体埋入式愈合与非埋入式愈合的临床疗效比较

Clinical effect of implant healing between submerged and non-submerged dental implants:a randomized controlled study

目的:观察后牙区Replace种植体埋入式愈合与非埋入式愈合的临床疗效。方法:本实验采取区段随机化分组方法,将40例患者(95颗种植)随机分为A组(埋入式愈合)和B组(非埋入式愈合),比较种植体负重后1年种植体周骨组织水平变化、牙菌斑、软组织炎症情况以及种植体存留率。采用SPSS16.0软件包对骨组织水平变化进行独立样本t检验,其余参数采用独立样本非参数检验。结果:2组种植体存留率均为100%,种植体周骨组织水平变化A组和B组分别为(0.16±0.46mm)和(0.04±0.35mm),P>0.05,无显著性差异;2组间种植体周牙菌斑聚集及软组织炎症情况也无显著性差异。结论:Replace种植系统非埋入式愈合可取得良好的种植体周软、硬组织以及骨整合,疗效良好。非埋入式可以替代埋入式愈合,作为Replace种植体植入的常规方案。

PURPOSE：To observe the clinical effect of implant healing between submerged and non-submerged dental implant in posterior lower jaw.METHODS：Totally 40 cases（95 implants,Nobel Replace System） were randomly divided into Group A（submerged healing） and Group B（non-submerged healing）.The peri-implant bone level,soft tissue inflammation,implant plaque aggregation,and implant retention were evaluated one year after implant loading.The change of bone level was calculated by independent t test while the others were calculated by independent non-parameter test using SPSS16.0 software package.RESULTS：The implant retention rate was 100% in both groups;the peri-implant bone levels in group A and group B were（0.16±0.46mm） and（0.04±0.35mm）,respectively.There was no significant difference between both groups in implant bone level,peri-implant tissue inflammation and implant plaque aggregation.CONCLUSIONS：Replace non-submerged implant healing merits good implant healing of soft and hard tissue and bone integration,with good clinical efficacy;non-submerged implant healing can be used as an alternative to submerged implant healing.
