Periimplantitis is a clinical situation seen around implants and charecterised by soft tissue inflammation together with adjacent bone loss. If left untreated, it ends up with regional bone loss and ultimately total loss of implant. Conventional algoritm for periimplantitis is mechanical treatment. Yet, Recent studies are showing that using laser procedure without mechanical treatment or as a supportive tratment may give successful results. It is verified that, laser procedures have antimicrobial effect and help removing small residues that cannot be reached by mechanical debridment. There are various results showing what kind of alterations this procedures may cause on implant surface. The aim of this study was to compare the effects of lasers on SLA surfaced titanium and roxolid discs. Three study groups were optained by using diode laser in CW mode with R-24B handpiece(808nm), Er:YAG laser(2940nm) in SP mode and Er:YAG laser in VSP mode. These groups were divided into two subgroups to compare roxolide and titanium materials. 13 titanium discs with 5 mm diameter and 13 roxolid discs with 5 mm diameter are used. 12 of these 13 titanium and roxolid discs are shooted with determinated laser doses into 2 subgroups. Other 1 of these 13 titanium and roxolid discs are planned as control groups without appling any laser dose on their surfaces. After the laser application titanium and roxolid discs were examined with SEM and profilomater for surface morphology, surface topography and 3-dimentional surface analysis and graphics. All results are compared with other groups, subgroups and control groups. More surface damage was observed in Er:YAG laser VSP mode group than SP mode group. Roxolid materials were effected more than titanium materials in all groups after laser applications. Diode laser was found to be safer for the treatment of periimplantitis.
