Background: Edentulism significantly impairs oral function, aesthetics, and quality of life in elderly patients. Conventional complete dentures often present limitations in retention and stability, whereas implant-supported overdentures offer improved prosthetic performance. This study aimed to compare patient satisfaction between complete dentures and implant-supported overdentures in patients aged 50–70 years. Methods: A prospective comparative study was conducted among 100 completely edentulous patients divided into two groups: complete denture (n=50) and implant-supported overdenture (n=50). After a 3-month adaptation period, patient satisfaction was assessed using a standardized questionnaire evaluating comfort, stability, mastication, aesthetics, and overall satisfaction. Statistical analysis was performed using independent t-test and chi-square test, with p<0.05 considered significant. Results: Implant-supported overdentures showed significantly higher satisfaction scores compared to complete dentures across all parameters. Mean overall satisfaction was 8.7 ± 0.8 in the implant group versus 6.6 ± 1.3 in the complete denture group (p<0.001). Comfort, stability, and masticatory efficiency were also significantly improved in the implant group (p<0.001). Patients with implant overdentures demonstrated better ability to chew hard foods and reported higher aesthetic satisfaction. Conclusion: Implant-supported overdentures provide superior functional and patient-reported outcomes compared to conventional complete dentures. They significantly enhance comfort, stability, and quality of life, making them a preferred treatment modality for edentulous patients aged 50–70 years, despite higher cost and surgical considerations.
