Background: Dental status, among other factors, has an impact on the nutritional status of the elderly. It has been shown that subjects wearing conventional complete dentures have a lower nutritional intake than do subjects having more than 20 teeth.Hence; the present study was undertaken for assessing of effect of age on prognosis dental implants. Materials & methods: 40 patients were enrolled in the present study. All the patients were divided into four study groups with 10 patients in each group as follows: Group 1: Patients within the age range of less than 20 years, Group 2: Patients within the age range of 20 to 40 years, Group 3: Patients within the age range of 41 to 60 years, and Group 4: Patients within the age range of more than 60 years. Dental implant therapy was carried out in all the patients. Follow-up was done after one year and thorough clinical and radiographic examination was carried out for assessing the prognosis. Results: Failure of dental implant occurred in 10 percent, 20 percent, 10 percent and 20 percent of the subjects of group 1, group 2, group 3 and group 4. Non-significant results were obtained while comparing the effect of aging on prognosis of dental implants. Conclusion: In comparison to young subjects, dental implants in geriatric patients had comparable prognosis. Key words: Dental Implant, Ageing, Prognosis.
