Abstract Aim To evaluate the efficacy of a reconstructive surgical procedure in single peri‐implantitis infrabony defects. Methods Seventy‐five patients with one peri‐implantitis crater‐like lesion with pocket depth ( PD ) ≥ 6 mm, were included. Each defect was assigned to one characteristic class, by an independent examiner. After implant decontamination, defects were filled with deproteinized bovine bone mineral with 10% collagen. Results At 1‐year follow‐up, four patients were lost and six implants removed. Treatment success, PD ≤5 mm and absence of suppuration/bleeding on probing ( BOP ), was obtained in 37 (52.1%) of the 71 implants examined. PD was significantly reduced by 2.92 ± 1.73 mm ( p < 0.0001). BOP decreased from 71.5 ± 34.4% to 18.3 ± 28.6% ( p < 0.0001). The mean number of deep pockets (≥6 mm) decreased from 3.00 ± 0.93 to 0.85 ± 1.35 ( p < 0.0001). Conclusions These results confirm the possibility to successfully treat peri‐implantitis lesions. There is lack of evidence of whether or not the resolution of the peri‐implant disease is associated with the defect configuration. Due to the fact that complete resolution does not seem a predictable outcome, the clinical decision on whether implants should be treated should be based on several patient related elements.
