The aim of the systematic review and meta-analysis carried out was to evaluate the effects of changing the prosthetic platform on peri-implant tissue after 1 year of prosthetic loading.
In November 2020, an electronic search was carried out in PubMed, EMBASE, Web of Science, and Scopus databases with the aim of obtaining all the randomized clinical trials that had been published in the preceding 10 years comparing the effects on the peri-implant tissue of implants with a prosthetic platform change and implants with a conventional platform for at least 1 year after prosthetic loading. Randomized model meta-analyses of the selected studies were performed to compare the results of the two implant groups in terms of vertical maintenance of bone level and increased probing depth.
Nine studies were included, summing up a total of 475 implants with prosthetic platform exchange and 462 implants with a conventional platform. Implants with prosthetic platform exchange had less peri-implant bone loss than implants with a conventional platform (mean difference of 0.255 mm, statistically significant) but suffered a greater increase in probing depth (mean difference of 0.082 mm, not statistically significant). However, the probing depth from One Study Remove revealed a statistically significant increase of 0.190 mm in the prosthetic platform exchange group compared to the conventional platform group.
Implants with platform switching suffer less peri-implant bone loss after 1 year of loading than implants with a conventional platform. Further long-term studies are required to observe how these differences vary over time.
本系统评价和荟萃分析的目的是评估修复体加载1年后更换修复体平台对种植体周围组织的影响。
2020年11月，在PubMed、EMBASE、Web of Science和Scopus数据库中进行了电子检索，目的是获取过去10年发表的所有随机临床试验，比较修复体加载后至少1年，修复体平台更换的种植体和传统平台种植体对种植体周围组织的影响。对所选研究进行随机模型荟萃分析，以比较两组种植体在骨水平垂直维持和探诊深度增加方面的结果。
纳入9项研究，总计475颗进行修复体平台更换的种植体和462颗传统平台种植体。修复体平台更换的种植体比传统平台种植体的种植体周围骨丢失更少（平均差异为0.255mm，具有统计学意义），但探诊深度增加更多（平均差异为0.082mm，无统计学意义）。然而，排除一项研究后的探诊深度显示，修复体平台更换组与传统平台组相比，探诊深度有统计学意义的增加，增加了0.190mm。
加载1年后，平台转换的种植体比传统平台种植体的种植体周围骨丢失更少。需要进一步的长期研究来观察这些差异如何随时间变化。
