Statement Of Problem: The implant abutment connection interface has been considered one of the major factors affecting the outcome of implant therapy. However, drawbacks of traditional meta-analyses are the inability to compare more than 2 treatments at a time, which complicates the decision-making process for dental clinicians, and the lack of a network meta-analysis.
Purpose: The purpose of this network meta-analysis was to assess whether the implant abutment connection influences the outcome of implant-supported prostheses.
