PURPOSE:: The aim of this study was to evaluate and compare immediate-loaded implant-retained mandibular overdentures and delayed-loaded implant-retained mandibular overdentures. MATERIALS:: Ten completely edentulous male patients received 40 dental implants. Patients were randomly divided into 2 equal groups, 5 patients each. Patients of both groups received conventional maxillary complete denture and had stage 1 surgery for placing 4 dental implant fixtures, 2 on each side anterior to the mental foramina. Group A: One-stage surgical procedure and immediate loading. Patients in this group received mandibular bar-retained overdenture supported by 4 endosseous implants loaded immediately after implant placement. Group B: The original 2-stage concept and delayed loading. Patients in this group received mandibular bar-retained overdenture supported by 4 endosseous implants that remained submerged for a period of 4 months before loading. The patients were evaluated clinically and radiographically immediately after overdenture delivery and after 6 months, 12 months, 18 months, and 24 months. RESULTS:: The results of clinical evaluation showed no statistical significant difference between the 2 groups regarding the effect of treatment. The radiographic assessment showed no statistical significant difference in mesial and distal alveolar bone loss at the different intervals of the follow-up period, except at the 12-month period, where immediately loaded implants showed a decrease in the amount of alveolar bone loss mesially and distally compared to delayed loaded implants. CONCLUSIONS:: The results suggest that immediate-loaded implants provide promising results compared to delayed-loaded implants and can be a possible alternative procedure in implant dentistry.
