Background: This study compared the oral health-related quality of life (OHQoL) of edentulous patients receiving implant-retained mandibular overdentures and conventional complete dentures. Methods: A quasi-experimental study was conducted in 2021 in Kerman, Iran, involving 40 edentulous patients who attended Kerman Dental School and private prosthodontic clinics. Half of the participants were treated with conventional mandibular complete dentures, and the other half received mandibular implant-supported overdentures. All participants completed the Oral Health Impact Profile for Edentulous Patients (OHIP-EDENT) questionnaire before treatment and three months after receiving their prostheses. Data were analyzed using the Shapiro–Wilk test, independent-samples t-test, paired-samples t-test, and one-way ANOVA, with a significance level set at P < 0.05. Results: The OHIP-EDENT scores significantly improved after treatment in both groups (P < 0.05), indicating an enhanced OHQoL. However, the overdenture group demonstrated significantly higher post-treatment OHIP-EDENT scores compared to the conventional denture group (P < 0.05). The number of implants (two, three, or four) did not significantly affect the total or domain-specific OHIP-EDENT scores (P > 0.05). Participants with non-splinted overdentures reported less favorable outcomes in psychological distress, physical disability, handicap, and total OHIP-EDENT scores compared with those using splinted overdentures (P < 0.05). Conclusion: Patients treated with mandibular implant-retained overdentures reported greater satisfaction and better OHQoL than those with conventional dentures. While the number of implants did not influence outcomes, splinting the fixtures substantially improved OHQoL and overall patient satisfaction.
