Resolution of peri‐implant mucositis at tissue‐ and bone‐level implants: A 6‐month prospective controlled clinical trial

Objective The objective of the study was to compare resolution of inflammation of naturally occurring peri‐implant mucositis (PM) at tissue‐level (TL) and bone‐level (BL) implants after non‐surgical mechanical debridement. Materials and Methods Fifty‐four patients with 74 Implants with PM were allocated in two groups (39 TL and 35 BL implants) and treated by means of subgingival debridement using a sonic scaler with a plastic tip without adjunctive measures. At baseline and at 1, 3, 6 months, the full‐mouth plaque score (FMPS), full‐mouth bleeding score (FMBS), probing depth (PD), bleeding on probing (BOP), and modified plaque index (mPlI) were recorded. The primary outcome was BOP change. Results After 6 months, the FMPS, FMBS, PD, and number of implants with plaque decreased statistically significantly in each group (p .05). After 6 months, 17 (43.6%) TL and 14 (40%) BL implants showed a BOP change in (17.9%) and (11.4%), respectively. No statistical difference was recorded between groups. Conclusions Within the limitations of present study, the findings showed no statistically significant differences in terms of changes in clinical parameters following non‐surgical mechanical treatment of PM at TL and BL implants. A complete resolution of PM (i.e., no BOP at all implant sites) was not achieved in both groups.
