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).

A dental curable composition capable of use as a dental material that can substitute part or all of a natural tooth, in particular, a resin material for dental cutting and machining in the field of dental care. When a block shape usable as the resin material is produced, while mechanical properties and aesthetic properties required for a crown prosthetic appliance are maintained, the dental curable composition can be molded and processed with pressure and heating while strain generated in the block is reduced and no cracks and chipping occur. The dental curable composition includes (a) a polymerizable monomer and (b) a filler in a weight ratio of 10:90 to 70:30, and 0.01 to 10 parts by weight of (c) a polymerization initiator and 0.001 to 1 part by weight of (d) a chain transfer agent being a terpenoid compound based on 100 parts by weight of the polymerizable monomer (a).

A method of installing a dental prosthetic device includes securing a first guide member to an alveolar arch in a mouth of a patient. The first guide member is utilized to achieve a substantially planar bone surface along the alveolar arch. A second guide member is coupled with the first guide member. The second guide member is utilized to install one or more implants in the alveolar arch through substantially planar bone surface. A dental prosthetic is secured to the one or more implants. The dental prosthetic includes nanoceramic material.
