Abstract
Introduction
Rehabilitation of partially edentulous patients presents both biomechanical and aesthetic challenges. Although metallic partial removable dentures (PRDs) provide durability and functional stability, traditional clasp-based retention may compromise aesthetics and patient comfort. Tooth-supported overdentures with ball attachments offer an alternative by enhancing retention, distributing occlusal forces more evenly, and improving the overall aesthetic outcome.
Observation
This case report describes the prosthetic rehabilitation of a patient with extensive edentulism using a metallic PRD supported by tooth-retained overdentures. Teeth 13 and 25 were prepared to receive ball attachments, ensuring optimal retention and stability. The clinical protocol included post space preparation, wax coping fabrication, polyvinyl siloxane impressions, and framework try-in. The final prosthesis was designed to maintain biomechanical balance while concealing metal components for a natural appearance.
Discussion
The use of ball attachments allowed for improved retention and stress distribution, preventing excessive load on the abutment teeth. The patient reported high satisfaction with both the functional performance and aesthetic integration of the prosthesis. Follow-up assessments confirmed the stability of the restoration, proper occlusal relationships, and enhanced comfort.
Conclusion
Tooth-supported overdentures using ball attachments represent a valuable approach in prosthetic rehabilitation, combining biomechanical efficiency with aesthetic considerations. This case highlights the clinical benefits of these attachments in improving retention, comfort, and patient satisfaction. Their integration into metallic PRDs offers a functional and aesthetic alternative to conventional clasp-based designs.
