STUDY OBJECTIVES AND METHODS

The purpose of this study was to evaluate the clinical outcomes and radiographic bone fill of reconstructive surgical treatment using the oscilating chitosan brush for implant surface decontamination. Nine patients with 11 Class I and III peri-implantitis defects were included. Following implant surface decontamination performed with a chitosan brush, guided bone regeneration (GBR) was performed by means of a bovine derived cancellous bone graft and collagen membrane. Clinical parameters such as full mouth plaque score (FMPS), probing depth (PD), bleeding on probing (BoP), recession, and radiographic bone level (RBL) were recorded at baseline and 1 year following treatment.

RESULTS

• All evaluated parameters, including PD, BoP, recession, RBL, and full mouth plaque scores, revealed significant improvements at 1 year follow-up compared to baseline (p < 0.05).
• The mean PD values reduced from 7.30 ± 1.29 to 3.78 ± 0.65 (p = 0.000). RBL was detected 5.50 ± 1.31 and 1.38 ± 0.74 at baseline and 1-year, respectively (p = 0.010).

CONCLUSIONS

Reconstructive surgical treatment of Class I and III peri-implantitis defects with GBR may be an effective treatment protocol when an oscilitating chitosan brush is used for surface decontamination.
