Summary
This study shows how using a 3D scanner with computer-aided design (CAD) can improve dental prosthetics. This digital workflow reduces costs and chair time for dental restorations.
Area of Science:
- Biomaterials and Biomedical Engineering
- Dental Prosthetics and Restorations
- Digital Dentistry and Computer-Aided Design
Background:
- Limited space between the residual ridge crest and prosthetic teeth presents challenges for clinicians and dental technologists.
- Accurate measurement and planning are crucial for successful prosthetic outcomes, especially for complete overdentures and fixed prostheses.
Purpose of the Study:
- To demonstrate the application of a touch probe 3D scanner integrated with computer-aided design (CAD) software.
- To evaluate the potential of this digital workflow in reducing clinical chair time and overall costs for dental prosthetics.
Main Methods:
- Utilizing a Pix30 3D Scanner (Roland DG Corporation) for scanning tooth arrangements and superstructures.
- Employing various CAD programs to position scanned data and precisely measure available space for superstructure fabrication.
- Assessing the impact of scanning limitations on treatment planning for complete overdentures and fixed prostheses.
Main Results:
- The integrated 3D scanning and CAD approach facilitates improved treatment planning for dental prosthetics.
- This digital workflow leads to reduced material waste and fewer diagnostic errors.
- Significant reductions in both clinical chair time and laboratory costs are achievable.
Conclusions:
- 3D scanning combined with CAD offers an efficient method for managing space limitations in dental prosthetics.
- The digital workflow enhances treatment planning accuracy, leading to cost savings and improved efficiency.
- Despite minor scanning limitations, the overall benefits for complete overdentures and fixed prostheses are substantial.
