Abstract

Following the extensive use of implant, the incidence of peri-implantitis increases. Guided bone regeneration has been used for the optimal treatment of this disease. Because implant surface was contaminated with plaque and calculus, cleaning and detoxification were needed for the reosseointegration when guided bone regeneration was performed.Various mechanical and chemical methods have been used for cleaning and detoxification of implant surface, air-powder abrasive and oversaturated citrate were known to be most effective among these methods. However, these methods were incomplete because these could not thoroughly remove bacteria of implant surface, moreover deformed implant surface. Recent studies for detoxification of the implant surface using laser were going on, CO2 laser and Soft Diode laser were known to be effective among these methods. The purpose of this study was to obtain clinical guide by application these laser to implant surface.
15 experimental machined pure titanium cylinder models were fabricated. The CO2 laser treatment under dry, wet and hydrogen peroxide condition or the Soft Diode laser treatment under Toluidine blue O solution condition was performed on the each of models. Each groups were examined with SPM and SEM to know whether their surface was changed.
The results were as follows:
1. Surface roughness and surface form weren't changed when CO2 laser was usedunder dry condition(P>0.05).
2. Surface roughness and surface form weren't changed when CO2 laser was used under wet condition(P>0.05).
3. Surface roughness and surface form weren't changed when CO2 laser was used under hydrogen peroxide condition(P>0.05).
4. Surface roughness and surface form weren't changed when Soft Diode laser was used under toluidine blue O solution condition(P>0.05).
From the result of this study, it may be concluded that the CO2 laser having relatively safe pulse mode and the Soft Diode laser used with photosensitizer can be used safely to treat peri-implantitis.
