However, in the case of a large number of missing teeth or a complete denture, since the position of the original tooth is not known, conventionally, the apex of the gingival part was set as the position of the artificial tooth arrangement, and teeth were arranged to form a denture. The shape of the curved line of teeth was unknown. Therefore, I have relied solely on the feeling and experience of dental technicians, so despite the patient's unique dentition shape,
Many are arranged according to the preference of the dental technician. Further, even when the same dental technician prepares the complete denture used by the patient again, the denture may be formed in different dental arch shapes.

る。Therefore, as a result of repeated research on the shape of the dental arch, the present inventor has found that a curve formed by hanging both ends of the chain and slowly hanging it, that is, a suspension curve, becomes the shape of the dental arch. We found that we were in tune
No. 3-201523 discloses a dental arch gauge made of a transparent plate formed in a substantially semi-circular shape having a side corresponding to the suspension curve. The dental arch gauge disclosed herein is convenient because the catenary side is very well aligned with the dental arch of the patient and serves as a guide when arranging artificial teeth. . However, with a dental arch gauge having such a shape, when the catenary side is aligned in the correct position with respect to the patient's dental arch, the gauge can be well coordinated if there are not some reference teeth left. However, in the case of a large number of missing teeth or a complete denture, there is a problem that the original positions of the teeth cannot be known.

A curve having a catenary shape of a book is shown. For example, when arranging artificial teeth in a maxillary model, the range formed between the curves 4 and 5 best fits the dentition of the patient. If a gauge is selected and used as the occlusal plane plate of the articulator, since it is a transparent plate, the artificial teeth can be accurately arranged along the curves 4 and 5 while observing the corresponding state with the occlusal plane. Moreover, the dental arch gauge of the present invention does not need to be aligned with the positions of the anterior teeth and the molars, which are the indexes of the dental arch, unlike the conventional dental arch gauges. It is easy to match the curve of, the original tooth position can be known, and the artificial tooth can be implanted at a position suitable for the patient. Further, when implanting artificial teeth in the mandibular model, the artificial teeth may be implanted so that the artificial teeth are positioned in the range formed between the curve 3 and the curve 5 shown on the gauge.
