Aspects Regarding Subtractive and Additive CAD-CAM Processes Applied in Prosthetic Dentistry

The paper presents some technical features regarding the realization of dental prostheses and models by modern CAD-CAM technologies that operate on both the subtractive principle and the additive principle highlighting the advantages and disadvantages for each manufacturing approach compared to traditional methods applied in dental prosthetics. It also describes the processing steps for making dental prostheses by CAD-CAM methods, the equipment used, as well as the characteristics of the resulting restorations.
