摘要： An intraoral scanning system comprises an intraoral scanner and a computing device. The intraoral scanner generates a intraoral scans of a dental site, the intraoral scans comprising at least a first intraoral scan and a second intraoral scan. The computing device receives the intraoral scans and determines a region of the second intraoral scan comprising a plurality of points that satisfy one or more potential artifact criteria based on a comparison of the second intraoral scan with the first intraoral scan. The computing device identifies the region as an artifact based at least in part on determining that the region satisfies one or more removal criteria. The computing device removes the region from the second intraoral scan responsive to identifying the region as an artifact.

摘要： An automated method for generating a prosthesis from a 3D scan data, the method includes extracting prep information of a prepared tooth from the 3D scan data, generating a two dimensional (“2D”) projection images by projecting the 3D scan data based on the prep information and generating a 3D prosthesis based on the 2D projection images using a generative adversarial network including a 2D encoder and a 3D decoder.

摘要： Dental bulk blocks for cutting machining are provided. The dental bulk block is a glass ceramic block having a structure in which crystalline phases including lithium disilicate as a main crystalline phase and lithium phosphate and at least one of cristobalite and tridymite as additional crystalline phases in an amorphous glass matrix. The dental bulk block is a functionally graded material (FGM) having gradations of size in the main crystalline phase along a depth direction thereof and having no interface at a gradation value change point at which a gradation value of size in the main crystalline phase changes. The dental bulk block is useful for the manufacture of artificial dental prostheses similar to natural teeth. Therefore, the present disclosure provides the effect of reducing the time and process of manufacturing artificial teeth protheses and increasing structural stability in teams of force distribution by functionally grading physical properties.
