Background and Aim: With the recent boom in dental implantology, implant supported or retained overdentures are not an uncommon treatment modality for completely edentulous patients. Still the relative numbers of these cases are drastically lower than the expected levels. This is particularly true for rural population. This study was conducted to evaluate the knowledge and awareness about mandibular implant overdentures among institutionalized completely edentulous patients in northern Indian region. Materials & Methods: A questionnaire-based survey comprised of 100 patients was completed. Total 100 Patients those visiting for complete denture fabrication were selected. A preformed questionnaire containing 10 questions about knowledge and awareness about mandibular implant overdentures was distributed among patients in their first visit of complete denture fabrication. This study comprised of patients who truthfully responded to this questionnaire. Response was recorded and data was processed statistically to estimate awareness level. Results: Statistical evaluation using statistical software Statistical Package for the Social Sciences (SPSS). The resultant data was subjected to suitable statistical tests to draw concrete inferences. Outcomes in the questionnaire showed that age group of 45-50 years had 3 males and 2 females, 51-55 years had 8 males and 4 females, 56-60 years had 12 males and 7 females and 61-65 years had 19 males and 12 females. Only 15 patients were fully aware of mandibular implant overdentures. The difference was significant for fourth age group. P value less than 0.05 was considered as significant. Conclusion: In the studied completely edentulous patients, the relative level of knowledge and awareness regarding mandibular implant overdentures was nearly at poor level. Majority of them do not even know about dental implantology. For those who were aware, the most common source of information was doctor. Furthermore, most of the patients were in misconception that mandibular implant overdenture surgeries possibly have harmful effects on eyes and ear.
