    Abstract: The invention relates to a denture base having a plurality of tooth socket compartments where one or more of the tooth socket compartments comprises a convex surface configured in step-like structure, and one or more prominences on the step-like structure. The invention further relates to a dental prosthesis including the denture base, at least one bonding agent, and a plurality of artificial teeth. Artificial teeth are bonded within tooth socket compartments such that each artificial tooth can rest upon the top of each prominence in the tooth socket compartment, maintaining a predetermined amount of bonding agent between the artificial tooth and the denture base. The denture base and dental prosthesis of the invention can better address the need for easier, more efficient and reliable set-up of artificial teeth in a denture base, and ensuring more consistent and predictable bonding of artificial teeth in a denture base.

    Abstract: Digitally designing artificial teeth for use in a dental prosthesis and/or dental restoration. Designing natural-looking functional artificial teeth based on computer-aided design using reference dentition articulated in a predetermined occlusal scheme as a basis for effective design. In particular, the occlusal surfaces of posterior artificial teeth are designed in a digital environment to provide effective consistent functional set-up and performance, especially across a variety of occlusal schemes, in the preparation of dental prostheses.

    Abstract: The invention relates to methods for preparing a three-dimensional digital model of a prosthetic denture base for fabrication using a light-based three-dimensional printing apparatus. A virtual reference model of a prosthetic denture base is prepared and manipulated to establish specific spatial orientation and angular inclination with respect to the build platform surface of the printing apparatus. Methods may include performing a corrective digital scaling process on the virtual reference model in order to achieve further improvements to dimensional accuracy in the fabrication of prosthetic denture bases.
