Summary
This study presents a new technique for verifying intraoral scanner accuracy in full-arch implant restorations. An implant index cast ensures predictable and accurate fitting of implant fixed complete dentures (IFCDs).
Area of Science:
- Dentistry
- Prosthodontics
- Digital Workflow
Background:
- Intraoral scanners are common for partial edentulism but their accuracy for full-arch implant restorations is debated.
- Conventional impressions can be cumbersome for full-arch implant cases.
Observation:
- A novel technique utilizes an implant index cast and a 3D-printed cast to verify intraoral scanning accuracy for complete-arch implant restorations.
- This method was applied in a clinical case of immediate loading for a maxillary edentulous patient.
Findings:
- The implant index cast, derived from the immediate interim prosthesis, effectively validates scanned data and printed models.
- This technique allows for precise control over the fit of digital restorations.
Implications:
- This digital workflow eliminates the need for conventional impressions and casts, enhancing predictability.
- It offers a reliable method for ensuring the accurate fit of final implant fixed complete dentures (IFCDs).
