Summary
Computer-aided design and computer-aided manufacturing (CAD-CAM) diagnostic prostheses improve planning for full-arch implant restorations. This method verifies impressions and evaluates esthetics before final fabrication.
Area of Science:
- Dentistry
- Biomaterials Science
- Prosthodontics
Background:
- Computer-aided design and computer-aided manufacturing (CAD-CAM) technology offers advantages for fabricating complete-arch implant-supported fixed prostheses.
- Zirconia prostheses layered with feldspathic porcelain present unique challenges requiring meticulous treatment planning.
Observation:
- A CAD-CAM high-density polymer diagnostic prosthesis was utilized in a clinical setting.
- This diagnostic prosthesis served to confirm the accuracy of the implant impression.
- It also facilitated the evaluation of the maxillomandibular relationship, esthetics, and phonetics.
Findings:
- The use of a CAD-CAM diagnostic prosthesis allows for preemptive verification of critical parameters before final prosthesis fabrication.
- This approach aids in identifying and correcting potential issues related to fit, occlusion, and esthetics early in the workflow.
Implications:
- Implementing CAD-CAM diagnostic prostheses can enhance the predictability and success rates of complete-arch implant restorations.
- This technique minimizes chair time and laboratory rework by ensuring accuracy and patient satisfaction before final milling and processing.
- It represents a valuable tool for clinicians planning complex implant-supported rehabilitations.
