[Comparative study of different CAD/CAM-system for making frameworks of nonremovable dentures]

Area of Science:

• Dental Technology
• Digital Dentistry
• Biomedical Engineering

Background:

• The integration of Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) systems has revolutionized dental prosthetics.
• Accurate reproduction of surface components, scanning cavities, and abutments is crucial for prosthetic fit and function.

Purpose of the Study:

• To comparatively evaluate the precision of different CAD/CAM systems in reproducing critical dental components.
• To assess the accuracy of measurements obtained from various CAD/CAM systems for frame gaps.

Main Methods:

• A comparative study was conducted on multiple CAD/CAM systems.
• Measurements of surface component reproduction, scanning cavity precision, and abutment accuracy were performed.
• Regional gap measurements of frames generated by these systems were recorded.

Main Results:

• Significant variations in the precision of surface component reproduction were observed among the evaluated CAD/CAM systems.
• The accuracy of scanning cavities and abutments differed across the systems.
• Measured values of the regional gap of frames showed variability depending on the CAD/CAM system used.

Conclusions:

• The choice of CAD/CAM system impacts the precision of dental component reproduction.
• System-specific variations in accuracy necessitate careful consideration during prosthetic workflow planning.
• Further research is recommended to optimize CAD/CAM system performance for enhanced prosthetic outcomes.
