HOW DO PERI-IMPLANT BIOLOGIC PARAMETERS CORRESPOND WITH IMPLANT SURVIVAL AND PERI-IMPLANTITIS? A CRITICAL REVIEW
ranging from 25% to 49.9% for eight treatment groups and ranging from 50% to 74.9% for six treatment groups. In seven treatment groups, a BoP ≥ 75% was reported. Two papers reported the modified bleeding index,81 one the Sulcus bleeding,82 and one gave only information about bleeding for implants diagnosed with peri‐implantitis.

Suppuration
Eight papers (Table 5) reported that 0%–20% of the implants showed suppuration independently from BoP. In four papers, this percentage corresponds nicely with the reported prevalence of peri‐implantitis (~10%–40%), but in the other four papers, it did not. The high prevalence of 20% in the paper of Chappuis et al. (2013) is explained by the inclusion of six previously lost implants as well as 13 successfully treated ones.14
Correlation between reported prevalence of peri‐implantitis and biologic parameters
Figures 3-5 report the Pearson r correlation coefficient, visualize the correlation between the different biologic parameters, and reported prevalence of peri‐ implantitis and follow‐up time. The dimension of the different bullets in the figures reflects the weight of the study.
