Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clasp designing surveyor device for a clasp designing process in a dental instrument.

[0002]

2. Description of the Related Art As is well known, for dental treatment, for example, a denture may be attached and used in place of a damaged or damaged tooth. For such a denture, an impression is taken in the patient's oral cavity, and a tooth model made of gypsum is created based on the impression. This tooth-shaped gypsum model very faithfully reproduces the gingival gingiva part of a patient, a healthy residual tooth part extending from the gingival gingiva part, and a defective tooth part due to breakage or damage. Based on this tooth-shaped plaster model, for example, a denture corresponding to the missing tooth portion of the patient is created.

The denture as described above is formed, for example, as shown in FIG. 4, by implanting and molding a tooth FT to be prostheticly mounted on a resin floor RF. The thus-formed denture has adjacent healthy residual teeth (hereinafter referred to as hook teeth ST) as an abutment tooth, and with respect to this abutment tooth, for example, a clasp C made of a wire clasp or a casting clasp. The denture is attached in a tying pattern. In this case, the clasp design process for setting the denture without any discomfort is regarded as an important issue.

As the clasp applied to the above dental treatment, for example, a wire clasp made of a metal wire material having a diameter of about 1 mm and a casting clasp formed by casting based on a wax mold are known. These clasps are selected from metallic materials such as Co—Cr alloys, Pt—Au alloys, Au and Pd.

As shown in FIG. 5, the clasp C has a curved arm portion AP that fits into the undercut region of the adjacent healthy remaining tooth ST and a leg embedded in the resin floor RF for the tooth to be treated. And a portion LP.

On the other hand, when designing the clasp, it is necessary to draw in advance the contour lines of the resin floor and the clasp, which are the constituent parts of the denture, for the tooth-shaped plaster model. When designing the clasp, it is difficult to insert and insert the denture, depending on the amount of undercut to the ridge of the tooth, unless the outline is drawn with due consideration of the condition of the ridge of the tooth.
Alternatively, there is a drawback that the setting maintenance power after the insertion and insertion is weak and the setting comes off immediately.

Therefore, in this clasp design,
The notation of the surveying line for the tooth-shaped plaster model is extremely important, and the quality of the notation of the surveying line determines labor saving of various processes related to the clasp design.

[0008]

Conventionally, the notation of the surveying line for this tooth-shaped gypsum model has been performed by a surveyor device. A conventional surveyer device is composed of a surveyor stand for horizontally setting a tooth-shaped gypsum model and a surveying line marking means in which a marking core is attached so as to extend along a vertical line. In this conventional surveyor device, the mode of marking the surveying line is as follows.

First, after fixing the tooth-shaped plaster model on a surveyor stand and deciding the attachment / detachment direction of the denture, a surveying line (the maximum protuberance of the tooth or mucous membrane) is applied to the tooth-shaped plaster model by means of a surveying line marking means. Mark. In this case, an undercut gauge was used to measure the amount of undercut according to the elasticity of the applied clasp material, the position of the claw was determined, and the clasp outline was drawn by hand. The description of the floor outline was also made by the same procedure.

On the other hand, in general, in an Acus type clasp design, in the case of a wire clasp, 2/3 from the open end of the curved arm portion, and in the case of a cast clasp, the open end of the curved arm portion. It is made by putting 1/2 in the undercut. However, the denture molded by this method has some drawbacks such as resistance to lateral movement during mounting and lifting on the prosthesis side. The cause is a phenomenon that occurs when the curved arm portion AP of the clasp C is in the pre-grasping state with respect to the claw tooth ST. This phenomenon is not a problem that can be solved by simply increasing the undercut amount, but it is necessary to lengthen the undercut region and design the clasp so as to hold the undercut ST to enhance the antagonistic action.

In the case of a line clasp, a method has been introduced in which the insertion area is lengthened from the portion with less elasticity near the root of the claw tooth ST to the tip of the claw, and in the case of this method, attachment of the denture At this time, the maintenance power becomes too tight and there is a high risk that it cannot be mounted, and the clasp design itself has been extremely uneven, depending on the experience and intuition of the operator.

Therefore, according to the present invention, under the above clasp design situation, it is possible to draw the clasp contour line very easily and labor-saving, regardless of whether it is a wire clasp or a casting clasp. SUMMARY OF THE INVENTION It is an object of the present invention to provide a surveyor device for clasp design which eliminates the drawbacks recognized in the conventional method as much as possible and enables the clasp to be manufactured with high uniformity.

In order to achieve the above-mentioned object, the present invention specifically provides a surveyor stand for setting a tooth-shaped plaster model, and a marking line for marking the tooth-shaped plaster model. And a surveying line marking means, wherein the surveying line marking means is a surveyor device for a clasp design for marking a surveying line on a tooth-shaped plaster model set on the surveyer table, The yard base includes a base, a support column rotatable with respect to the base, a first pivot shaft intersecting the support column, and a second pivot shaft orthogonal to the first pivot shaft.
