Prosthesis For Obtaining Tooth Balance Information {Prosthesis For Obtaining Tooth Balance Information}

The present invention relates to an implant for obtaining tooth balance information, and in more detail, by acquiring tooth balance information in the patient's oral cavity when manufacturing a dental pore, and balancing the dental pore based on the obtained tooth balance information It relates to an implant for acquiring tooth balance information that enables the production of patient-customized dental pores.

In general, a number of processes are performed to produce dental pores (or'tooth implants') such as gold teeth and porcelain teeth. Among the various processes, the process of taking an impression in which the teeth of the patient's mouth are duplicated in a negative shape in the dentistry, a model making process in which plaster is injected into the impression body obtained through the impression-taking process to convert it into a positive shape, and a pin is placed in the produced tooth model. The process of performing, basing process of forming the base gypsum part on the bottom of the tooth model, and the damaged tooth part of the tooth model using a tool such as a saw cut the boundary between the tooth and the tooth to form a partial tooth model. It includes a sawing process in which the tooth model 28 is detachable from the base gypsum part, and a mounting process in which the tooth model is mounted on the articulator to check the occlusal relationship between the maxillary and the mandibular tooth model.

When manufacturing a dental prosthesis through this process, in particular, the vertical and horizontal lines become very important reference lines when manufacturing the front teeth of the dental prosthesis, that is, the anterior prosthesis. Here, the horizontal line is the chewing surface of the tooth, that is, the occlusal plane, and the vertical line is the line between the two teeth at the center of the human nose and the center of the front teeth, that is, the canonical line.

That is, the dental pores must be symmetrically balanced based on the occlusal plane and the canonical line.

However, as shown in FIG. 1, when viewed in the conventional mounting process, several vertically shaped optical lines appear between partial tooth models formed in the sawing process, and in addition, since the teeth cannot be modeled accurately horizontally during the impression-taking process. Optical illusion lines in a horizontal shape appearing in the basing stage forming the base plaster part on the model. Since these optical illusion lines are not horizontal or vertical lines, the front teeth are arranged crooked in the future, and the resulting dental pores are defective and need to be corrected or remanufactured, so opportunity costs such as time and material costs There was a problem of this unnecessary waste.

First, in the waxing (S70) step, wax is put on the tooth model to wax up the entire tooth shape.

In the methylcoping step (S80), the wax is separated from the waxed-up tooth model, and then buried with an investment material to create a negative mold, and then melted and injected the metal into the negative mold to make a positive dental prosthetic model. Then, a metal coping body is manufactured by cutting so as to allow the ceramic material to be layered.

In the porcelain layering step (S90), the porcelain material is placed on the metal coping body and baked at a high temperature to generate dental pores.

In the contouring step (S100), the dental pores made in the porcelain layering step are processed to reproduce the surface like a natural tooth.

In the glazing step (S110), the dental pores reproduced like natural teeth are baked at a high temperature to polish them.

In this way, in the mounting process to check the occlusal relationship of the tooth model, the incisors are crooked in the completed dental procedure by using the patient's tooth balance information obtained through the implant for obtaining tooth balance information to balance the dental procedure. Problems such as misalignment, poor occlusion and lifting do not occur.

As described above, according to the present invention, by using the patient's tooth balance information obtained through the implant for obtaining tooth balance information to balance the dental pores, it is possible to produce an accurate balance of the dental pores and the customized dental pores.

In addition, by using the patient's tooth balance information obtained through the implant for obtaining tooth balance information to balance the dental pores, it improves the convenience and efficiency of manufacturing the dental pores, and reduces the defect rate of the dental pores, resulting in material cost and Opportunity costs can be reduced.
