Abstract
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); however, no statistically significant differences were found between TL and BL implants (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.
