Despite high success rates of dental implants, many biological and mechanical complications exist. Peri-implantitis is a chronic
infection around dental implants with irreversible crestal bone loss. The aim of this study is to report the various surgical treatment
techniques of peri-implantitis using surface decontamination with tetracycline & Er-YAG laser.
3 patients who had peri-implantitis with suppuration were treated with 3 different surgical treatment methods.
- Pt1 : open flap debridement
- Pt2 : coronally advanced flap operation with subepithelial connective grafting
- Pt3 : open flap debridement with alloplast grafting
Tetracycline and Er-YAG laser were used to decontaminate all the implant surfaces.
Clinical parameters such as probing depth(PD), BOP were recorded before surgery and at 3 month follow-up appointment. From
the baseline to 3 month follow-up , the mean reduction of probing depth was measured 4mm, 3mm, 3mm, in patient 1, 2, 3,
respectively.
All patient did not show BOP and suppuration. The findings of this case report suggest that clinical improvements were obtained
by surgical treatment using surface decontamination with tetracycline & Er-YAG laser. [THE JOURNAL OF THE KOREAN
