治療が通常である。(Disadvantages of conventional technology) In general, tooth decay often erodes the upper part of the tooth, that is, the crown, and the treatment for this is to mechanically remove the affected area of the tooth and then use materials such as gold, silver, or ceramics. The usual treatment is to cover the tooth with a dental prosthesis (crown material).

ている。 Conventionally, such dental prostheses are created by first removing the affected area of the patient's tooth that requires a prosthesis and its surroundings, then creating a mold of the tooth (abutment tooth), and then attaching an internal prosthesis to this mold of the tooth (abutment tooth). First, a wax prototype for a dental prosthesis is taken by covering the entire surface of the tooth from the crown to the neck, that is, the area where the dental prosthesis (dental crown material) needs to be crowned, with dental wax. Then, based on the information, the wax model is embedded in a sand mold (embedding material), and molten metal from a dental prosthetic mold is injected into this sand mold (embedding material), and the wax is melted and created. After cooling the molten metal filled in the cavity, the sand mold (embedding material) is removed.

Conventionally, a separating material is first applied to the surface of the tooth that requires a tooth-shaped prosthesis (abutment tooth), then a layer of soft wax is applied, and then dental wax is formed as a surface layer on the surface of the soft wax layer. However, the upper surface of this dental wax was manually cut (carved) or raised (wax up) to create a shape similar to the crown of a tooth.

があり問題であつた。 During this conventional wax pattern work, the wax up work or carving work is done by hand, so it requires a high level of work, it is a long and precise work, and the quality varies depending on the manufacturer, and the work is done by hand. This has been problematic because it requires a lot of manufacturing time.
そこで、この様な欠点を解消せんとして特公昭
52−23515号に開示される如く「歯牙鋳造金属冠

製作することからなる歯牙鋳造金属冠の製造方法
であつた。 As shown in Fig. 5, the technique disclosed in this Japanese Patent Publication No. 52-23515 is that a negative mold (Devcon mold) is made using a flexible material from a metal crown matrix in which a standard-form natural tooth is sculpted and restored. A semi-ready made elastic wax crown 51 is formed by injecting and press-fitting an inlay wax or a vinyl synthetic wax obtained by heating and mixing wax and ethylene vinyl acetate copolymer into the negative mold of the metal crown matrix using an injection molding machine (No. 5). (See Figures A, B, and C), when manufacturing this cast metal crown, select a semi-ready-made elastic wax-shaped crown 51 that most closely resembles the prosthetic tooth, heat it, and set it on each tooth socket so that the occlusal surface is placed on the opposing tooth. After correcting the tooth neck and adjusting the contact surface with the adjacent tooth at the same time, this modified semi-prefabricated elastic wax-shaped crown 51 is used to make a metal casting of the same type. This was a method of manufacturing a tooth casting metal crown, which consisted of manufacturing a crown.
この既開示の技術は成るほど標準形態天然歯か
らなる半既製弾力製蝋型冠を調製してなるもので
ある程度従来の欠点を解消したものであるがこの
歯牙鋳造金属冠の製作方法にはいまだ次の欠点が
あつた。 Although this disclosed technique is one in which a semi-ready-made elastic wax-shaped crown is prepared from a standard-form natural tooth, and the drawbacks of the conventional technique have been overcome to some extent, there is still no method for manufacturing this tooth-cast metal crown. It had the following drawbacks.

いない。 That is, in the previously disclosed semi-ready-made elastic wax-shaped crown 51, not only the crown portion 52 but also the tooth neck portion 53 are adjusted from a standard-form natural tooth.
For correction and correction of 3, it is necessary to warm up beforehand.
In the current situation where there are many deviations in the amount of removal of the tooth neck 53 due to differences in individual technical ability, the problem of complicating the work of correcting and correcting the tooth neck 53 has not been sufficiently solved.
更なる欠点としては、各歯列位置における歯の

えつて大きく時間を要する問題が新たな欠点とな
つていた。 Further disadvantages include differences in tooth type at each dental position and differences in the size and shape of individual teeth, making it difficult for unskilled workers to adjust the shape and shape of multiple crowns at once. A new drawback has been that the position of the dentition must be selected in advance from among standard-form natural teeth, and the selection process is rather time-consuming.

で、この歯冠材用型材１は全体が通常の舌顎大臼
歯の上方部すなわち歯冠部に近い形状にのみ成形
されている。 In FIGS. 2A, B , and C and FIG. 3, reference numeral 1 denotes one tooth crown material forming the tufted tooth crown material mold. It is shaped only in the upper part of a molar tooth, that is, in a shape close to the crown part.
すなわち、上面２は通常の咬合面に近似形状と
され、側面３の深さは歯冠部が被われる深さとさ
れる。 That is, the upper surface 2 has a shape that approximates a normal occlusal surface, and the depth of the side surface 3 is such that the crown portion of the tooth is covered.
上面（咬合面）２と側面３は、樹脂ワツクスで
一体成形されている。 The upper surface (occlusal surface) 2 and side surface 3 are integrally molded with resin wax.
この歯冠材用型材１の底面はなく内部は空洞と

２図Ａ及びＢ中にθで示す咬頭傾斜角は補綴を要
する歯の削除量（即ち支台歯について言えばその
歯の高さ）の大小に応じ、０〜30゜の範囲で設定
するのが望ましい。 However, in this invention, the cusp hexagonal angle is not limited to an acute angle. In other words, the cusp inclination angle indicated by θ in Figures 2A and B is within the range of 0 to 30 degrees, depending on the amount of tooth removed that requires prosthesis (i.e., the height of the abutment tooth). It is desirable to set this.
すなわち、削除量が小さい場合には咬頭傾斜角
θを０に近く設定し、かつ削除量が大きい場合に
は30゜に近く設定する。 That is, when the amount of removal is small, the cusp inclination angle θ is set close to 0, and when the amount of removal is large, it is set close to 30°.
この咬頭傾斜角θに従い、つまり咬頭傾斜角θ
が小さい場合には歯冠材用型材１の裏面ａは平面

歯が患者に違和感なく被冠できるかどうかはこの
歯頸部の精密性に依る。 This tooth neck is the most important part of the tooth crown material, and whether or not the prosthetic tooth can be crowned without discomfort on the patient depends on the precision of this tooth neck.
しかもこの歯頸部は患者でないので歯科医師に
よりその削除量が異なり、その削除量の偏差が個
人差に依つて最も大きい箇所でも有る。 Furthermore, since this tooth neck is not a patient, the amount of removal varies depending on the dentist, and it is also the location where the deviation in the amount of removal is greatest depending on individual differences.
従つて、標準化することが現在の歯科技術でも
最も困難な箇所でもある。 Therefore, standardization is the most difficult aspect of current dental technology.
この考案においてはこの部分を標準化しないこ
とにより逆に歯頸部の精密性を図れるものであ
る。 In this invention, by not standardizing this part, it is possible to improve the precision of the tooth neck.
歯科用ワツクス１５は若干の加熱で直ちに軟化
して歯冠材用型材１と一体化する。 The dental wax 15 is immediately softened by slight heating and becomes integrated with the tooth crown material mold 1 .
この状態で対合歯モデルと咬合させて、咬合面
（切端）の微調整を行う。 In this state, the tooth is brought into occlusion with the opposing tooth model, and the occlusal surface (incisal edge) is finely adjusted.

る効果をも有する。 As explained above, the tufted tooth crown material of the present invention is molded into the shape of the occlusal surface using resin wax that naturally resembles the teeth, so it can be used to create a wax prototype of a dental prosthesis through wax pattern work. Therefore, the carving work and wax up work during the wax pattern work, which were always necessary in the past, can be completely omitted, and each tooth crown material shape is only deep enough to cover the crown of the tooth. Tooth mold of the patient's tooth that requires prosthesis (prosthetic tooth) A wax pattern using a conventional mold material, because it is only necessary to fill and adjust only the cervical part of the tooth that requires crowning and adjustment. This reduces the difficult work process of heating the tooth neck and adjusting it from a standard product, and it also simplifies precise adjustment of the tooth neck where the amount of removal is uneven, which in turn ensures that the prosthetic tooth does not make the patient feel uncomfortable. Moreover, since the mold for tufted tooth crown material is arranged according to the shape of the tooth row and is shaped like a tuft, the row of teeth of the interlocking teeth and the tooth row of the mold for the tufted tooth crown material can be easily separated. Because it can be selected and used just by looking at it, it has the effect of making it easier to obtain molds for manufacturing accurate dental crown materials compared to conventional dental crown materials, and has the effect of improving dental care.
