Abstract: A prosthetic tooth for a denture comprises a lingual or palatal surface, an opposing vestibular surface, opposing proximal surfaces, an incisal or occlusal surface and an opposing apical surface, wherein at least one projection extends from a surface of the tooth for spacing the surface adjacent to the projection from a denture base. Alternatively, a denture base for a denture comprises a space having a surface for receiving a tooth, wherein at least one projection extends from a surface of the denture base for spacing the surface adjacent to the projection from the tooth. The projections assist with providing a substantially uniform or even layer of sufficient adhesive between a tooth and a denture base so that the strength of the bond between the tooth and the denture base is improved. In addition, a projection extending from a surface of a tooth makes it easier to determine whether the tooth is positioned correctly when the tooth is aligned with a denture base.

Abstract: A set of artificial teeth for a denture comprises a maxillary unit and a mandibular unit. When set up in lingualised occlusion or balanced occlusion, at least one of following occurs: the palatal cusp (1a) of the maxillary posterior tooth (7a) fits into the distal fossa (1b) of the mandibular posterior tooth (8a); the palatal cusp (2a) of the maxillary posterior tooth (7b) fits into the distal fossa (2b) of the mandibular posterior tooth (8b); the mesial palatal cusp (3a) of the maxillary posterior tooth (7c) fits into the central fossa (3b) of the mandibular posterior tooth (8c); the distal palatal cusp (4a) of the maxillary posterior tooth (7c) fits onto the marginal ridge (4b) of the mandibular posterior tooth (8c); and the mesial palatal cusp (5a) of the maxillary posterior tooth (7d) fits into the central fossa (5b) of the mandibular posterior tooth (8d).
