- the crown has a multi-layered structure with an enamel layer on the surface and a dentin layer inside, like human natural teeth.
- the thickness of the enamel layer gradually decreases as the tip of the model tooth approaches the thickest root, and the thickness of the enamel layer near the cervical line that forms the boundary between the root and the crown is 0.02- 0. It is very thin, about 3mm.
- the thinnest enamel layer in the vicinity of the cervical line forms a portion adjacent to the crown portion in the root portion and a root surface layer in the vicinity thereof.
- the enamel layer that is thinnest in the vicinity of the cervical line extends to the root side while maintaining its thickness, or while gradually increasing the thickness or gradually decreasing the thickness, It may extend to the club side.
- the thickness and width are appropriately selected according to the desired model tooth shape, but the thickness of the surface layer is about 0.02 mm to 0.3 mm, preferably about 0.05 mm to 0.2 mm.
- the portion adjacent to the crown portion of the root portion and the vicinity thereof refers to a range of about 5 mm from the root of the tooth neck to the root end, and if this width is too narrow, the vicinity of the pole of the tooth neck
- the enamel layer of the crown of the tooth tends to be missing. Therefore, the width of the surface layer of the root is preferably 0.5 mm or more, more preferably lmm or more. It is desirable that the surface layer of the tooth root portion is formed over substantially the entire circumference of the tooth root portion, but the surface layer of the tooth root portion may be partially formed.
- the enamel layer and the dentin layer forming the crown portion may be formed of different materials, or may be the same material, but in that a cutting feeling closer to natural teeth can be obtained.
- the material of the enamel layer is preferably harder than that of dentin.
- the hardness of the enamel layer depends on the material used. For example, when the standard is a resin material, the hardness is about 110 to 130 on the Rockwell M scale (according to JIS-K6911). It is desirable to use a hardness of about 70 to 110. Furthermore, Ename By setting the hardness difference between the ruby layer and the dentin layer to be 10 to 60, preferably 20 to 50, in terms of the hardness, it is possible to obtain a cutting feeling closer to natural teeth.
- FIG. 1 (a) is a view showing an example of the external shape of the dental practice-like model tooth of the present invention
- (b) is a cross-sectional view showing its internal structure
- FIG. 2 (a) is a view showing an example of the external appearance of a conventional dental practice-like model tooth
- FIG. 2 (b) is a cross-sectional view showing its internal structure.
- the multilayer model tooth for dental practice of the present invention is composed of an enamel layer (3) as a surface layer and a dentin layer (4) as an inner layer. It consists of a crown part (1) and a root part (2) that are modeled and the enamel layer (3) extends from the tip of the model tooth to the root part (2) side beyond the neck line (6) The surface of the root portion (2) adjacent to the crown portion (1) and the vicinity of the root portion (2) is covered with the enamel layer (3) of the crown portion (2).
- the thickness of the enamel layer (surface layer (5) of the root portion) covering the root surface at the position of the tooth neck line (6) is 0.02 mm to 0.3 mm.
- the average roughness of the centerline is RaO. 1 micrometer or more and less than 10 micrometer, preferably 0.15 micrometers or more and minute unevenness of about 5 micrometers. Is provided to reflect the laser beam!
- the surface portion may be provided with a dent or a discolored portion due to deposition, which is shaped like a cavern, or an adhering material imitating tartar.
- the crown (1) is connected to the root (2) so that it can be placed on a predetermined jaw model.
- the root portion (2) connected and integrated with the crown portion (1) is not particularly limited in structure except for the adjacent portion to the crown portion and the surface layer in the vicinity thereof. It may be a single layer structure or a multilayer structure, and may have a structure having a plurality of roots closer to natural teeth, or a simple root structure in which natural teeth are simplified. In addition, a pulp cavity or a root canal imitating a natural tooth may be formed inside. Furthermore, it is also possible to provide a layer imitating a cementitious layer on the surface layer other than the surface layer adjacent to the crown and the vicinity thereof.
- a raw material for such model teeth generally known materials can be used,
- ceramics or other ceramics, or thermoplastics such as acrylic, polystyrene, polycarbonate, polyester, or thermosetting such as melamine, urea, unsaturated polyester, phenol, epoxy, etc.

- a hard material obtained by filling the above-mentioned polymerizable monomer material with an inorganic material such as silica in the enamel layer of the crown portion is used. It is desirable to use a material having a relatively low hardness, mainly made of acrylic, melamine, epoxy, or the like, as a material for the layer or root part.
- the color tone of these materials is not particularly limited, but is appropriately adjusted to a desired color tone.
- the method of toning is not particularly limited, and may be adjusted to a desired color tone by appropriately combining various known pigments and dyes.
- the method for producing such a model tooth is appropriately selected depending on the material to be used. For example, when synthetic resin is the main raw material, a known method such as general injection molding or press molding is applied. I can do it.
- the dentin layer and the root portion were filled and solidified in an injection mold for forming a shape in which the dentin layer and the root portion were integrated, and the dentin layer and the root portion were integrated.
- this molded product is mounted at a predetermined position in the injection mold for molding the enamel layer shape, and then the material to be the enamel layer is filled into the mold, and from the dentin layer and the root portion.
- the outer enamel layer of the molded product is laminated and integrated.
- the shape of the root of the molded product to be mounted on the mold for molding the enamel layer is the surface described above. By forming the layer, the surface layer of the root portion is formed simultaneously with the material filling of the enamel layer.
- the multi-layer model tooth for dental practice of the present invention can be easily manufactured by such a method, but the present invention is not limited to this method.
- the enamel layer is formed first
- the explanation was made based on the drawing of the front teeth, but the multilayer model tooth for dental practice of the present invention is not limited to the front teeth, and the same effect can be obtained in molars.
