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.
