Abstract
OBJECTIVES: The purpose of this prospective, parallel group-designed, randomized controlled clinical study was the evaluation of the effectiveness of an air-abrasive device (AAD) for nonsurgical treatment of peri-implantitis. MATERIAL AND METHODS: Twenty five patients, showing at least one implant with initial to moderate peri-implantitis, underwent anoral hygiene programme and were randomly treated using either (1) AAD (amino acid glycine powder) or (2) mechanical debridement using carbon curettes and antiseptic therapy with chlorhexidine digluconate (mechanical debridement (MDA)). Clinical parameters were measured at baseline and 12 months after treatment (e.g. bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL)). RESULTS: At 12 months, the AAD group revealed significantly higher (p < 0.05; unpaired t test) decrease in mean BOP scores when compared with MDA-treated sites (41.2 ± 29.5 vs. 16.6 ± 33.4%). Both groups exhibited comparable PD reductions (AAD = 0.5 ± 0.9 mm vs. MDA = 0.4 ± 0.9 mm) and CAL gains (AAD = 0.6 ± 1.3 mm vs. MDA = 0.5 ± 1.1 mm) (p > 0.05; Mann-Whitney test, respectively). CONCLUSIONS: Within its limitations, the present study has indicated that both treatment procedures resulted in comparable but limited CAL gains at 12 months. Furthermore, it could be detected that AAD was associated with significantly higher BOP decrease than MDA. CLINICAL RELEVANCE: The present results have indicated that nonsurgical therapy of peri-implantitis using both AAD and MDA resulted in comparable PD reductions and CAL gains after 12 months of healing. The BOP reductions were significantly higher in the AAD in comparison to the MDA group. So, AAD may be more effective for nonsurgical therapy of peri-implantitis than MDA.
