The amount of marginal bone loss is considered an important criterion to evaluate the implant therapy outcome and to predict the prognosis of the implant rehabilitation. The purpose of this systematic review was to examine the available literature comparing clinical and radiological outcomes like the implant failure rates and marginal bone loss around platform switching dental implants platform matching ones. English randomized controlled human clinical trials, comparing one or more PS groups with one or more PM groups, with at least 12 months of follow-up after loading and 10 implants, providing carefully the number of PS- and PM- implants used as well as implant survival and data concerning bone level changes or marginal bone loss around implants, were included. Fifteen publications, involving a total of 1439 implants and 642 patients, were eligible. More studies showed less mean marginal bone loss around PS implants and none of them showed differences in terms of implant failure rates. This review confirmed a great effectiveness of platform switching technique to prevent marginal bone resorption. Nevertheless, this result should be interpreted cautiously because of the heterogeneity of the included studies.
边缘骨吸收量被认为是评估种植治疗效果和预测种植修复预后的重要标准。本系统评价的目的是审查现有文献，比较临床和放射学结果，如种植失败率以及平台转换种植体与平台匹配种植体周围的边缘骨吸收情况。纳入了英国随机对照人体临床试验，将一个或多个平台转换组与一个或多个平台匹配组进行比较，加载后至少随访12个月且有10颗种植体，需详细提供所使用的平台转换种植体和平台匹配种植体的数量以及种植体存留情况，以及关于种植体周围骨水平变化或边缘骨吸收的数据。共有15篇出版物符合要求，涉及1439颗种植体和642名患者。更多研究表明平台转换种植体周围的平均边缘骨吸收较少，且在种植失败率方面均未显示出差异。本评价证实了平台转换技术在预防边缘骨吸收方面具有显著效果。然而，由于纳入研究的异质性，这一结果应谨慎解读。
