Dental CAM Dataset Alignment for Precise Prosthesis Milling

The patent applies preliminary action by pre-defining reference geometries in both the CAD dataset and CAM dataset before the integration process. These reference geometries (such as alignment markers or coordinate systems) are established in advance to enable automatic and precise alignment during dataset integration, eliminating the need for manual adjustment and ensuring accurate positioning of the dental prosthesis design within the manufacturing dataset.

The patent applies local quality by differentiating the blank structure into regions with different properties. The blank is designed with an inhomogeneous structure where specific local areas contain geometric features (such as varying thickness, surface textures, or embedded markers) that correspond to the gingival margin region. This allows the milling process to automatically generate realistic gingival impressions in those specific areas while maintaining material efficiency overall.
