合状態が重要であるので、咬合器が用いられる。Conventionally, artificial teeth made of acrylic resin, sulfone resin, hard resin, ceramics, etc. are widely known as artificial teeth for dentures, and these are, for example, 50-.
Like T3, it is standardized by a code number that represents the size and shape represented by the length and the width. On the other hand, as a method of manufacturing a denture using such an artificial tooth, a method of first making a mold from a patient to make a jaw model and implanting the artificial tooth therein is adopted. Artificial teeth are used for implanting artificial teeth, especially in the case of molars, because the proper occlusion state is important due to the relative relationship between the adjacent left, right, upper and lower teeth.

代表的な二つの考え方である。Here, the proper occlusion state means that the upper and lower corresponding teeth are not improperly deviated from the center position of occlusion during occlusion. For example, when moving the lower jaw, the full-balanced occlusion with the condition of proper occlusion that there is always an occlusion point somewhere in the corresponding upper and lower teeth, and the mountain part inside the oral cavity of the upper tooth is lower. Two typical dentistry ideas are lingualized occlusion, in which the condition of proper occlusion is to be in a state of always sliding on the side tooth surface.

りの割合に対応ができる。That is, each element forming the denture can be almost standardized, and for example, the artificial teeth 21 and 31 can be standardized as described above. In addition, it is possible to standardize the horizontal horseshoe shape of the dentition of human teeth and the so-called spline curve arrangement in the vertical direction, and there are two types of ideal occlusal state: full balance occlusal and lingualized occlusal. Well known among traders. Therefore, for example, prepare several types of tooth and jaw models having the shape of the standard wax bed, prepare several types of standardized artificial teeth, and use an articulator to allow an expert to spend time, for example, four pairs of molars. For each, plant one by one on the floor of the wax floor, and repeat the correction to obtain the proper occlusion state. First, make a set of the reference maxillary artificial tooth part and the reference mandibular artificial tooth part in which the proper occlusion state was obtained, and then set the reference maxillary artificial tooth part and the reference mandibular artificial tooth part set in the proper occlusion state. While maintaining the above, the set of the upper holding tool 23 and the lower holding tool 33, which are positioned with respect to each other, is joined to form a model artificial tooth assembly. Providing the necessary types of such model artificial tooth assemblies can meet a considerable proportion of the total demand for dentures.
