Objectives: The effect of implant-retained mandibular overdentures using the recently introduced intraradicular-stud attachment (OT Reverse/3) needs to be investigated. Therefore, a comparison of the OT Reverse/3 with the traditional extraradicular-stud type on alveolar bone height was conducted over 18-months period. Patients’ satisfaction with the restorations was also reported. Materials and Methods: Twenty edentulous patients were included in the study. Each patient received two implants in the interforaminal area and a mandibular overdenture. Patients were randomly divided into Ball and OT Reverse/3 groups. Once patients were adapted to their overdentures, they were placed on a recall program for 18-months. Alveolar bone height around the implants was measured. Patients’ satisfaction was reported after 6-months from using the restorations. results: During 18-months period, alveolar bone height showed statistically significant better results in patients who used the OT Reverse/3 attachments than those whom were offered the ball attachments. Patients of the two groups were satisfied in different functions. Conclusion and clinical relevance: Based on the results obtained from this study and within its limitations, the clinician may be able to choose the OT Reverse/3 attachment to retain mandibular implant overdentures as it may preserve alveolar bone height around the supporting implants if compared to the ball attachments.
