Background: Dental implants have become today an important treatment option for oral rehabilitation in patients with lost teeth. The present study was conducted to determine association of oral hygiene and peri- implantitis. Materials & Methods: The present study was conducted in the department of prosthodontics on 112 cases of both genders (males- 62, females- 50). Patients were divided into 2 groups of 56 patients each. Group I comprised of healthy patients without periodontitis and group II consisted of patients with periodontitis. The presence of periodontitis was confirmed by clinical attachment loss, probing pocket depth and bleeding on probing. The presence of radiolucency on radiographs around implant confirmed Peri- implantitis. Results: Out of 112 patients, males were 62 and females were 50. The difference was non- significant (P> 0.05). Group I and II comprised of 56 patients each. The difference was non- significant (P> 0.05). Peri- implantitis was seen in 2 patients in group I and 14 patients in group II. The difference was significant (P< 0.05). Conclusion: There is direct relation between chronic periodontitis and peri–implantitis. All patients who receive dental implants need to be free from periodontitis in order to ensure success.
