“…These results with the conventional treatment to manage PM were markedly inferior to those reported previously in the literature ranging between 38% and 83.3% (Hallstrom, Persson, Lindgren, Olofsson, & Renvert, 2012;Heitz-Mayfield et al, 2011;Menezes, Fernandes-Costa, Silva-Neto, Calderon, & Gurgel, 2016;Pulcini et al, 2019;Riben-Grundstrom et al, 2015). However, there are other factors that influence the position of the peri-implant mucosal margin and probing depth other than the inflammatory changes, such as the implant depth; implant angulation or the thickness of the peri-implant mucosa (Renvert, Persson, Pirih, & Camargo, 2018). In fact, the GEE analysis has shown that after adjusting for baseline PPDi, differences between groups in mBI at 6-month evaluation were still statistically significant, and baseline PPDi had no impact in the results at any time point (p = 0.06).…”
