Accuracy of Clinical Parameters in Predicting/Diagnosing Peri‐Implant Bone Loss

Clinical signs considered indicative of peri-implant mucositis (presence of BoP, visual redness) usually precede peri-implant bone loss. Implants with a recent history of bone loss always present with concomitant BoP. However, the predictive/diagnostic value of detecting one or two spots of BoP is limited by its low specificity. Implants with BoP at six sites or SoP are more likely to exhibit bone loss over time. During follow-up, BoP at six sites, profuse bleeding, SoP, PPD ≥ 6 mm, or increases in PPD/PISTD over time have high specificity for diagnosis of recent peri-implant bone loss.
