Description

[Detailed Description of the Invention] This utility model is applied to the root part of a tooth mold in order to easily and accurately attach and detach the tooth mold of the removable tooth type method.

 Although there are metal and plastic pins that determine the attachment / detachment direction of the tooth mold in the conventional removable tooth type method, it is difficult to set the pin direction to the tooth mold with certainty and set it up with the structure only with the pin. It was For this reason, there are machines that determine the direction in which pins are planted, but due to their high price, they are rarely used, and many of them rely on visual inspection and other factors, and were uncertain.

 The present invention solves these problems, and is a pin having a function of determining the direction in which the pin is planted.

 This will be described with reference to the drawings. A functional part that determines the direction of planting the pin (1) when the retaining part (2) of the pin (1) is fixed to the root of the tooth model (5) of the removable tooth type method. By closely contacting (3) with the bottom surface of the tooth mold (5) in parallel, the tooth mold (5) can be fixed to the root of the tooth mold (5) with a certain direction. In addition, a rotation prevention function part (4) is attached to prevent rotation around the pin.

 Since the present invention has such a structure, the pin is set up in the tooth form with a certain direction, and the attaching / detaching direction of the tooth form of the removable tooth type method is determined, so that the detachment can be easily and accurately performed. In particular, in the case where a large number of removable dental molds are to be planted, it is important to make the attachment / detachment direction accurate.

 In addition, there is no need for a machine to determine the planting direction, and the work is low cost and easy.

 The pin may be made of resin, resin, carbon, etc., as well as metal or plastic, as long as it has high hardness. Further, the shape is not limited to a cone, and any shape such as a pyramid, a cylinder, or a prism that can be easily and accurately attached / detached may be used.
