Background The aim of this study was to assess the reconstructive potential of a submerged healing approach for the treatment of infraosseous peri‐implantitis defects. Methods Patients with a diagnosis of peri‐implantitis were recruited. Implant suprastructures were removed before the surgical treatment, which included implant surface and defect detoxification using implantoplasty, air‐power driven devices, and locally delivered antibiotics. The augmentation procedure included a composite bone graft and a non‐resorbable membrane followed by primary wound coverage and a submerged healing of 8 months, at which point membranes were removed, and peri‐implant defect measurements were obtained as the primary outcome. Secondary endpoints included assessment of cone‐beam computed tomography (CBCT) and probing depth (PD) reductions. Results Thirty implants in 22 patients were treated. A significant clinical bone gain of 3.22 ± 0.41 mm was observed at 8 months. Radiographic analysis also showed an average gain of 3.47 ± 0.41 mm. Three months after installment of new crowns, final PD measures showed a significant reduction compared to initial examinations and a significant reduction in bleeding on probing compared to examinations at the pre‐surgical visit. Conclusions Reconstruction of infraosseous peri‐implantitis defects is feasible with thorough detoxification of implant sites, and a submerged regenerative healing approach.
