Introduction: Over the years, several different implant systems have been introduced, and the indications for implant rehabilitation have gradually been extended 2. Although an high success rates have consistently been reported for many implant systems, complications leading to loss of osseointegration still occurs 3. Thus, oral hygiene and maintenance are imperative, because implants, as well as teeth, are susceptible to accumulation of bacterial plaque and calculus formation. The aim of the present study was to evaluate and compare the in vivo cleaning efficacy of the three systems (air powder, curette, laser) comparing at the same time the alterations of the titanium abutment surface in terms of roughness.
Methods: Forthy-two patients (25 males and 17 females) were included in the study. The 42 healing abutments were treated by the same clinician (UC).
Results and conclusions: The rate of debris removal by the air powder was higher than that for the laser and than that for the curettes. The SEM analysis showed that the air powder system did not induce significant differences of the abutment if compared to the curettes as well as to the laser.
