The present invention relates to a tooth model fixing pin used in manufacturing a tooth model. In particular, the insertion pin and the insertion pin case constituting the fixing pin have a narrow trapezoidal shape so that the cross-sectional shape is simple and fits the shape of the tooth arrangement. It is made of silver metal, and the inserting pin case is formed of synthetic resin such as polypropylene so as to increase mutual bonding force, and the pin cap with openings formed on both side walls of the lower part of inserting pin case and cut line formed under It is configured to be connected to the baseformer, it is characterized in that it is configured to be easy to use.

Conventional tooth model fixing pin is composed of a cross-sectional shape of the inserting pin and the inserting pin case is formed by vertically cutting both sides of the cylinder and inserting the rubber pin cap at the lower part of the inserting pin case to insert and insert the insertion pin, inserting pin case It is difficult to manufacture because it consists of three parts, which are pin caps, and it has a problem of inaccuracy in precision and manufacturing price. Also, when the fixing pin assembly is embedded in the baseformer, the preparation procedure is complicated, which makes it difficult to use. .

The present invention has been developed to improve the above-mentioned drawbacks as described above in detail with reference to the accompanying drawings.

The present invention is connected to the inserting pin (1) and the inserting pin and the insertion pin case and the insertion pin case embedded in the baseformer, which is connected to the inserting pin (1) formed with a model tooth connection part (1a) attached to the upper end of the tooth model. It is made of a pin cap that is incised and embedded in a baseformer while accommodating a lower portion of the insertion pin.

In particular, the insertion and insertion pin case of the present invention is configured in the trapezoidal cross-section of the trapezoid to adapt to the tooth arrangement shape, the trapezoid is a trapezoidal shape with a narrow side toward the inner side and a wide side toward the outer side around the long side. As it is configured to correspond to the tooth arrangement arranged in the arch form, the stomach becomes thicker and thinner downward.

In addition, the inserting pin (1) of the present invention is made of metal (nickel plating on the zinc surface), the model tooth connecting portion (1a) protrudes on the top, the model tooth (1b) is attached, the inserting pin case (2) must be inserted The trapezoidal insertion hole (2a) is formed to be inserted properly and consists of a trapezoidal tubular body formed with a through-hole (2b) (2c) formed on both sides of the lower wall, the material is formed of a synthetic resin, such as polypropylene, and the insertion hole in the lower end ( 3a) is formed in the center portion and the pin cap (3) formed in the recessed groove (3c) is connected to the bottom portion (3b) is characterized in that the incision line (3d) formed on the outer periphery of the connecting portion is formed integrally.

The present invention has been made so that the insertion pin (1) and the insertion pin case (2) constituting the fixed pin is a trapezoidal cross-section that can be installed without interference between teeth, the insertion pin is made of metal and shovel Since the stripping case is made of synthetic resin such as polypropylene, the elasticity is better than that of metal, and the upper part is thinner and the lower part becomes thinner. Therefore, when the metal insertion stripping pin is inserted into the trapezoidal insertion hole (2a), it is inserted smoothly while maintaining a slight tension. It is easy to bond and stable coupling is prevented, and when it is buried in the baseformer, the gypsum liquid constituting the baseformer comes into close contact with the outer periphery of the inserting pin case (2) while a part of the through hole (2b) in the lower side wall of both sides ( 2c) has the advantage of being able to bury the fixed pin firmly to the baseformer through contact with the inserting pin, and the pin cap is also The bottom part 3b is embedded in the baseformer so that the bottom part 3b is exposed to the bottom of the baseformer. In this state, when the insertion pin is pulled out, the bottom part 3b of the pin cap 3 exposed to the bottom of the baseformer 4 is recessed in the groove ( 3c) is brought into contact with the pointed tool and pulled out, the incision line (3d) of the pin cap is separated and the insertion pin case and the pin cap are separated so as to escape out of the baseformer. It can be separated to the upper part by loosening in the insert pin case, so that the model tooth can be easily removed from the baseformer.

Therefore, the present invention is convenient to remove or insert the insertion pin in the insertion pin case.

In addition, the insertion and insertion pin case of the present invention is a trapezoidal cross-section of the cross-sectional shape is simple, but the cross-linking is perfect, so that the combination is not forward direction is not combined, the insertion without error is inserted into the baseformer Since it is firmly embedded to hold the insertion pin, it has the advantage of maintaining precision even if the insertion pin is repeatedly inserted and removed several times.The insertion pin case and the pin cap are integrally connected so that the pin is easy to use. The advantage is that you get the benefit of the comfortable talpin relax.

Moreover, the present invention can reduce the manufacturing cost, so that it is possible to supply an inexpensive fixing pin.
