摘要

Peri-implantitis is a common biologic complication that impacts the hard and soft tissues around dental implants. Oral bio-films are considered to be the main etiologic factor for various oral diseases including periodontitis and peri-implantitis. The various treatment options for the management of peri-implantitis include both surgical and non-surgical treatment approaches which focuses mainly on the decontamination and removal of the bio film and calculus over the implant surfaces. The present in-vitro study aims to evaluate the changes in the implant surface topography of commercial implants after instrumentation with four different mechanical debridement instruments. A total of eight titanium failed implants were used in this study. Two implants were assigned to each of the 4 groups namely Titanium curette (TC) (IMPM13/14T—Implant scaler titanium, HuFriedy, Chicago, ILUSA), Carbon fibre curette (CC), Plastic Curette (PC)—(IMPLACARE™ II, HuFriedy, Chicago, IL, USA), Metal curette (MC) (4R/4L Curette, HuFriedy, Chicago, IL, USA). The intragroup analysis were not statistically significant for all the four groups. The pairwise comparison between Titanium and Plastic group showed a statistically significant difference in Rq and Ra values. Within the limitations of the present study, we may conclude that the Plastic curettes cause comparatively less surface alterations and can be preferred for the debridement of titanium implant surfaces in the management of Peri-implantitis.
