CAD-CAM IN PROSTHODONTICS: The Evolution of Prosthetic Manufacturing

Comprehensive Summary of CAD/CAM in ProsthodonticsComputer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) represents a fundamental digital revolution in modern prosthodontics, transforming the traditional process of creating dental restorations. This technology integrates advanced digital imaging, software design, and automated manufacturing to produce highly accurate, durable, and aesthetically pleasing prostheses.The workflow begins with Digital Data Acquisition. Instead of messy, uncomfortable putty impressions, an intraoral scanner captures a precise 3D image of the patient's prepared tooth and surrounding dentition. This high-resolution digital model ($STL$ or $PLY$ file) is immediately transferred to the design software.Next is the Computer-Aided Design (CAD) phase. The dental professional utilizes specialized software to design the final restoration (e.g., a crown, bridge, veneer, or custom implant abutment) virtually. This design process allows for precise control over marginal fit, occlusion, contour, and contact points, ensuring the restoration integrates perfectly with the patient’s existing bite and neighboring teeth.
