Implant suprastructures were removed at the time of the intervention, to aid with the debridement process which included curettage, implantoplasty, air\u2010power driven devices, and locally delivered antibiotics. The infraosseous part of peri\u2010implant defects were augmented using a composite bone graft and an absorbable membrane to be secured around the replaced healing abutments without attempting to submerge the implants. After 8 months, direct peri\u2010implant defect measurements were obtained to serve as the primary outcome. Secondary outcomes included of radiographic bone changes, and probing depth (PD) and bleeding on probing (BOP) changes at 12 months.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At the time of the surgical re\u2010entry (8 months), a statistically significant clinical and radiographic defect fill was observed (average of 2.33 and 1.63\u00a0mm, respectively). Approximately 3 months after crown replacement, 12 months from the surgical intervention, a significant PD (1.51\u00a0mm) and BOP (65%) reduction were also noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Considering its limitations, the use of a non\u2010submerged approach (with removal of implant crowns) led to
