Aim: The main goal and purpose of this study was to compare and evaluate the mandibular anterior residual ridge resorption in four implant-supported overdentures and conventional complete dentures. Methods and Material: This study involved two groups of 20 patients with different prosthetic constructions. Group (1) mandibular complete dentures (CDs) as a control (10 patients). Group (2) mandibular overdentures supported by four implants placed in the interforaminal region and the first molar region following the two-stage surgical procedure and early loading protocol as a test group (10 patients). Evaluation of anterior residual ridge resorption (RRR) was carried out at baseline, at the time of surgery, and 06 months using CBCT and mucosal thickness was assessed at baseline, three months, and six months. Statistical analysis: The data was statistically analysed by using the Mann-Whitney u test. Results: The mean change in ridge resorption from baseline to 6 months in the control group is 0.38 ± 0.01(p-value 0.006). Whereas the mean shift in ridge resorption from baseline to 6 months in the test group was 0.15 ± 0.10(p-value 0.006). The mean change in mucosal thickness from baseline to 6 months in the control group is 0.54 ±0.04(p-value 0.796). Where 0.44±0.05 (p-value 0.796). Conclusion: Within the limitations of the study, it was concluded that implant-supported overdentures (ISODs) are an effective treatment modality in the rehabilitation of completely edentulous mandibular arches with improved patient satisfaction, chewing ability and in terms of ridge resorption, mucosal thickness and retention when compared to conventional complete dentures (CDs). Key-words: Conventional complete dentures (CDs), Implant-supported overdentures (ISODs), Residual ridge resorption (RRR), Cone-beam computed tomography (CBCT).
