Summary
A high-strength zirconia resin-bonded fixed dental prosthesis (RBFDP) offers a durable, minimally invasive solution for replacing a lost mandibular incisor. This advanced restoration preserves tooth structure and avoids long-term complications like infraocclusion.
Area of Science:
- Dental Prosthodontics
- Biomaterials Science
Background:
- Replacing a missing mandibular incisor requires careful consideration of various treatment options.
- Conventional prostheses, implant-supported restorations, and resin-bonded bridges each have specific selection criteria.
- Patient-specific factors influence the choice of restoration for optimal outcomes.
Purpose of the Study:
- To present a case study on the restoration of a missing left mandibular incisor in a young female patient.
- To evaluate the efficacy of a specific type of resin-bonded fixed dental prosthesis (RBFDP) for this indication.
- To highlight the advantages of modern CAD/CAM fabricated zirconia restorations.
Main Methods:
- A two-retainer, high-strength, monolithic, multi-layered zirconia resin-bonded fixed dental prosthesis (RBFDP) was designed and fabricated.
- Computer-aided design and computer-aided manufacturing (CAD/CAM) technology was employed for precision.
- Minimally invasive tooth preparation techniques were utilized to ensure optimal bonding.
Main Results:
- The chosen zirconia RBFDP demonstrated excellent durability and aesthetic integration.
- The minimally invasive approach preserved valuable tooth structure.
- The restoration was well-adapted to accommodate potential dental changes over time.
Conclusions:
- A CAD/CAM fabricated, multi-layered zirconia RBFDP is a viable and effective treatment for a lost mandibular incisor.
- This restorative approach offers long-term durability and tissue preservation.
- It presents a favorable alternative to implant-supported restorations, mitigating risks such as infraocclusion.
