Abstract
OBJECTIVES: To evaluate the 10-year outcomes of a regenerative surgical treatment of single peri-implantitis intrabony defects, by means of deproteinized bovine bone mineral with 10% collagen (DBBMC). MATERIAL AND METHODS: The original population consisted of 26 patients with one crater-like defect, around either SLA or TPS dental implants, with a probing depth ≥ 6 mm and no implant mobility. After debridement and surface decontamination, the defects were filled with DBBMC. Subsequently, patients were placed in an individualized supportive peri-implant/periodontal therapy (SPT) program. RESULTS: Fourteen patients (8 SLA & 6 TPS) reached the 10-year examination. The overall implant survival rate was 67%, 80% for the SLA and 55% for the TPS implants. During SPT, five patients were lost to follow-up, eight patients needed additional antibiotic and/or surgical therapy, seven patients had the implant removed. PD was reduced from 6.6 ± 1.3 to 3.2 ± 0.7 mm in SLA and from 7.2 ± 1.5 to 3.4 ± 0.6 mm in TPS. BOP decreased from 75.0 ± 31.2% to 7.5 ± 12.1% (SLA) and from 90.0 ± 12.9% to 30.0 ± 19.7% (TPS). Treatment success was found in 5 of the 12 SLA (42%) and in 4 of the 14 TPS (29%). CONCLUSIONS: The proposed reconstructive treatment, followed by SPT, was able to maintain in function the majority of SLA implants, although the overall treatment success was limited and many of TPS implants were removed. Therefore, the decision to treat implants affected by peri-implantitis should be based on several factors, including surface characteristics. This article is protected by copyright.
