Background: The present study determined peri- implant condition in periodontal weak patients. Materials & Methods: 140 dental implants were taken in study. The clinical parameters such as visible plaque index (VPI), gingival bleeding index (GBI), probing pocket depth (PPD) and bleeding on probing (BoP) were recorded. Digital intraoral radiographs were taken for the detection of marginal bone loss. Each implant was classified as health, clinical stability, peri-implant mucositis and peri-implantitis. Results: Implants were classified as healthy in 28, stability in 27, mucositis in 40 and Peri- implantitis in 45. The difference was significant (P< 0.05). The mean PPD in healthy implant was 4.2 mm, in stable implant was 5.6 mm, implant with mucositis was 5.7 mm and with peri- implantitis was 5.9 mm. BL >2 threads was observed in 4 patients with stability and 40 patients with peri- implantitis. BOP was seen in 84 sites in patients with mucositis and at 102 sites in patients with peri- implantitis. Conclusion: Dental implants placed in periodontal week patients may have high long-term survival rates. Key words: Dental implants, Gingival bleeding index, Probing pocket depth.
