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.
