【考案の詳細な説明】
(イ) 本考案の目的
（産業上の利用分野）
本考案は歯型支台模型に使用する可撤模型用の
ピンに関するものである。[Detailed description of the invention] (a) Purpose of the invention (industrial application field) The invention relates to a pin for a removable model used in a dental abutment model.
（従来の公知技術）
従来の公知技術に係るダウエルピンは円柱状の
単体であるために次のような欠点があつた。(Conventional Known Technique) Since the dowel pin according to the conventional known technique is a cylindrical unit, it has the following drawbacks.
単体であるために数本のピンを平行に植設す
ることが至難で、そのために熟練と同時に補助的
機械器具が必要とされる。円柱状であるため
に、ピンの下端を支持する支持孔が小さく長いた
めワツクス等でめづまりした際取出しが不充分
で、そのため支台歯を元の位置に戻すのが容易で
ないばかりか、浮上つて変形の原因となる。また
円柱体の場合は横揺れや回転し易い。 Since it is a single piece, it is extremely difficult to implant several pins in parallel, which requires skill and auxiliary mechanical equipment. Due to the cylindrical shape, the support hole that supports the lower end of the pin is small and long, so when it becomes clogged with wax, it is not easy to remove it, and it is not easy to return the abutment tooth to its original position. This may cause deformation. Moreover, in the case of a cylindrical body, it is easy to sway and rotate.

台を損傷することなくピンの着脱が可能である。(Operation of the present invention) When using the present product as a model pin, a groove 9 for embedding the base 1 in the tooth mold support 8 is created, the base is inserted into the groove, and secondary plaster is poured. The grooves 2 and 2' of the base are filled with plaster to maintain the pin 6 stably. Therefore, the pins can be planted parallel to each other as shown in FIG. 2 without any special training. When the tooth-shaped upper abutment 8 with the pin attached as described above is placed on the soft plaster that should constitute the lower abutment 10, the legs 4 act as stoppers to prevent the pin from sinking, and the abutment 8 Support it with legs 4 in a state where it floats on a soft lower support without being buried. Therefore, as shown in FIG. 5, after the lower abutment has hardened, the tooth mold upper abutment 8 and the lower abutment 10 can be easily separated by pushing up the lower ends of the legs. Divide the necessary parts of the separated upper part and return them to their original positions. In this way, the pin can be attached and detached without damaging the lower abutment.

のである。(Embodiment) To explain the embodiment of the present invention in detail with reference to the drawings, grooves 2 having a U-shaped cross section are formed on both the front and back surfaces of the upper base 1 of a band-shaped curved plate made of synthetic resin such as epoxy resin.
2' are arranged opposite to each other in the horizontal direction, and a large number of protrusions 3 and several legs 4 are arranged in a comb-teeth shape downward from the lower side of the base in the longitudinal direction.
are arranged in parallel through a groove 5 having an arcuate cross-section to form a pin body 6, and a groove 7 having an arcuate cross-section is formed on the lower back side of each of the protrusions, and the lower end of the pin body is thin. This is what I did.

勝れた利点がある。(c) Effects Since the present invention has the above-mentioned configuration, unlike the conventional single pin, it is extremely easy to implant it parallel to the toothed abutment, and therefore, the technical work at home can be done efficiently. . Also, since the pin has a certain width when cut into pieces, the pin will not rotate or sway, causing deformation. Since it is made of synthetic resin, it is very inexpensive, and the pin body 6 can be heated and bent to match the curvature of the jaw, making it convenient. Lower abutment 1
When the upper abutment 8 with the pin body attached is placed on the soft plaster that constitutes 0, the foot acts as a stopper, so it will not be buried, and the lower abutment will not be damaged when it is separated and cut after hardening. It has the advantage of not having to worry about anything.
