Aim To (i) identify factors associated with the probability of a peri‐implant site to be positive to bleeding on probing (BoP+) and (ii) compare BoP+ probability around dental implants and contra‐lateral teeth. Methods In 112 patients, data related to 1725 peri‐implant sites and 1020 contra‐lateral dental sites were retrospectively obtained. To analyse the association between patient‐, implant‐ and site‐related factors and BoP+ probability, a logistic, three‐level model was built with BoP as the binary outcome variable (+/−). Results BoP+ probability for a peri‐implant site with probing depth ( PD ) of 4 mm was 27%, and the odds ratio increased by 1.6 for each 1‐mm increment in PD ( p < 0.001). Also, BoP+ probability was higher in females compared to males ( OR = 1.61; p = 0.048), and lower at posterior compared to anterior dental implants ( OR = 0.55; p < 0.01). No significant difference in BoP+ probability was observed between peri‐implant and contra‐lateral dental sites when controlling for the difference in PD . Conclusions The probability of a peri‐implant site to bleed upon probing is (i) associated with PD , implant position and gender, and (ii) similar to that observed at contra‐lateral dental sites when controlling for the effect of PD .
