Aim: To evaluate and compare patient perspectives on implant-supported overdentures and conventional complete dentures using a structured questionnaire in completely edentulous patients.

Materials and methods: This observational questionnaire-based study included 20 completely edentulous patients who were initially rehabilitated with conventional complete dentures and subsequently treated with implant-supported overdentures. Patient perspectives were assessed using a structured 15-item questionnaire evaluating satisfaction, functional performance, aesthetics, complications, and acceptance. Descriptive statistics and Chi-square test were used for statistical analysis, with significance set at p < 0.05.

Results: Implant-supported overdentures demonstrated significantly higher overall satisfaction, improved comfort, superior denture stability during mastication, and increased confidence during speech compared to conventional complete dentures (p < 0.05). Prosthesis-related complications such as pain, gag reflex, and denture instability were reduced following implant overdenture rehabilitation. A majority of patients expressed a preference for implant-supported overdentures and willingness to recommend them.

Conclusion: Within the limitations of this observational study, implant-supported overdentures showed superior patient-reported outcomes compared to conventional complete dentures.
