Artificial teeth are arranged in plates capable of being attached in an oral cavity as a dental prosthetic appliance, in which one or more linear arrangement direction indication parts showing the arrangement direction in the plates are provided on an occlusal plane of each of the molar teeth. At least one set of arrangement direction indication parts of the adjacent molar teeth is configured so as to extend generally in parallel direction. At least one set of arrangement direction indication parts of the antagonist upper molar teeth and lower molar teeth is configured so as to extend generally in parallel direction. The artificial molar teeth are arranged at an appropriate position according to the oral cavity environment of each patient, without requiring advanced skills and experiences, and are applicable to various arrangements of artificial teeth.

Method of arranging artificial molar teeth

Artificial teeth arranged in plates attachable in an oral cavity as a dental prosthetic appliance, in which arrangement direction indication parts showing a directivity of arrangement in the plates extending in an apical-cervical direction or in a mesiodistal direction are provided at a vestibular side or an oral side. The arrangement direction indication parts extending in the apical-cervical direction are positioned linearly as seen from the vestibular side in an occluded state of mandibular teeth and maxillary teeth. The arrangement direction indication parts extending in the mesiodistal direction are positioned linearly as seen from the vestibular side in the state in which the teeth are arranged in the plates. The artificial teeth are arranged at an appropriate position according to an oral environment of each patient, without requiring advanced skill and experience.

Method of arranging artificial teeth

In a set of artificial teeth, at least one of mutually adjacent artificial anterior teeth includes abutting faces which contacts linearly with the other one so as to form abutting lines and capable of continuously moving the positions of the linear contact, the abutting faces being formed of any one of circular columnar surface, elliptical columnar surface, and conical surface.

The present invention provides a one-component dental adhesive composition which can exhibit excellent adhesion to both materials of a dental ceramics and an organic composite containing an inorganic compound, and is excellent in can-stability. More particularly, the present invention provides a one-component dental adhesive composition comprising 1 to 60 parts by weight of (a) a silane coupling agent, 1.0 to 20.0 parts by weight based on 100 parts by weight of the (a) component of (b) an acidic group-containing polymerizable monomer, and 28 to 99 parts by weight of (c) a volatile organic solvent.

An artificial anterior tooth capable of grinding food is provided. The lingual side of an artificial anterior tooth is provided with a protuberance for forming a frictional surface dented in an arch shape as seen from the mesiodistal direction, and the labial side of an opposite artificial lower tooth is provided with a protuberance for forming a sliding surface abutting the frictional surface and sliding on the frictional surface by a sliding motion of the upper and lower jaws.

The present invention provides a dental resin cement which is excellent in a mechanical strength, workability and storage stability, and a dental primer which significantly improves adhesiveness of the dental resin cement both to enamel and dentin of a tooth. According to the present invention, a salt of barbituric acid is used as a polymerization initiator in the dual-cure two-paste type dental resin cement being excellent in workability and storage stability to improve the storage stability, and a primer containing barbituric acid and amine is applied to a surface of a tooth to significantly improve adhesiveness of the dental resin cement both to enamel and dentin of teeth.

An object of the present invention is to provide a one-pack type dental adhesive composition which can exhibit excellent adhesion to any material, for example, dental ceramics, organic composites containing inorganic compounds, dental noble metals and dental non-noble metals, and also has excellent storage stability. Disclosed is a one-pack type dental adhesive composition comprising a silane coupling agent as a component (a), an acidic group-containing polymerizable monomer as a component (b), a sulfur atom-containing polymerizable monomer as a component (d), and other components.
