Tooth Supported Overdenture Using Castable Precision Attachments with Modified Impression Technique: A Case Series

Abstract Preventive prosthodontics emphasizes preserving natural teeth to enhance prosthetic stability and longevity. Tooth-supported overdentures serve as a crucial treatment modality, improving retention, reducing alveolar bone resorption, and providing psychological benefits to patients. This paper presents a series of case reports demonstrating the successful rehabilitation of a partially edentulous mandibular arch using a tooth-supported overdenture with precision attachments and copings. A detailed clinical approach, including case selection, treatment planning, and prosthetic execution, is discussed to highlight the advantages of this cost-effective alternative to conventional complete dentures and implant-supported prostheses.
