Purpose/Question

Is there an impact of platform switching (PS) on marginal bone level (MBL) changes around endosseous implants compared to implants with platform matching (PM) implant abutment configurations?

Type of Study/Design

Systematic review and meta-analysis

Level of Evidence

Level 2: Limited-quality, patient-oriented evidence

Strength of Recommendation Grade

Grade B: Inconsistent, limited-quality patient-oriented evidence

Section snippets

Selection Criteria

A systematic literature search was done in the electronic databases PubMed/Medline, Web of Science, Journals@Ovid Full Text and Embase. The search strategy used search term and MeSH. Moreover, to detect data from unpublished studies, the following electronic registers of clinical trials were searched, from the following websites http://apps.who.int/trialsearch/; http://www.clinicaltrialsregister.eu/; www.clinicaltrials.gov; www.centerwatch.com; www.controlledtrials.com. Finally a manual search

Commentary

The change of the peri-implant bone level is considered an important criterion for the evaluation of implant therapy outcome and evidence for the presence or absence of peri-implant tissue health.1, 2, 3 Therefore, efforts were made to maintain peri-implant marginal bone loss (MBL) stability after and throughout the prosthetic loading phase. In recent years, platform-switching has been increasingly investigated as a viable technique to decrease the amount of the MBL that occurs around an
