Description

Plate for dental model articulators {A PLATE FOR ARTICULATOR OF THE DENTAL MODEL}

The present invention relates to a plate for a dental model articulator, and more particularly, the molding can be formed quickly and conveniently with the supply of a plaster to connect and fix the dental model so that the use of the dental model and the occlusion can be easily performed. A dental model articulator plate.

If the teeth are not properly cared for, pathogens can penetrate the teeth and cause decay or gum disease, and if the tooth is pulled out or severely damaged, the area is treated and the affected area is not affected or replaced. There is a method of restoring damaged or rotten teeth to a normal state, which is planted with artificial teeth or prosthetic work on existing teeth.

In order to replace or prosthetic teeth with artificial teeth, the dental clinic makes negative patterns of the patient's teeth and sends them to the laboratory. The laboratory makes dental models by injecting dental cement into the negative ones. Depending on the number of teeth to be treated or prosthetic, a partial tooth model, one tooth model, a total tooth model, etc. are created to create only the corresponding tooth to be treated. To prepare a tooth model of the clam teeth.

In the case of working teeth and clam teeth, the correlation between the teeth and the artificial teeth for the final occlusal and chewing structure of the patient is finally determined to make the optimal prosthesis and artificial teeth. The mandibular structure should be reproduced. The articulator is a device designed to reproduce the upper and lower mandibular structures that match the tooth structure of the patient.

On the other hand, the following will be described in more detail with respect to the manufacturing method of the tooth model and the manufacturing method of the tooth model and articulator produced in the conventional laboratory.

Impressions or bites are floated in the dental clinic, and the impressions or bites are sent to the dental laboratory, and the casting stones are carried with the patient's impressions or bites. Use) to float the teeth. When the casting stone hardens after a certain time, the finished teeth are polished. After finishing, the treatment is performed, ie, the pinning is performed on the bottom of the teeth or the surrounding tooth model where the prosthesis is to be performed. Will be performed.

Pining is to drill the groove into which the fixing pin (also called the dowel pin) will be inserted into the bottom of the finished tooth model, and apply the adhesive to the top of the fixing pin by inserting it into the processed groove. The pin work of the fixing pin, which is fixed and coupled to the bottom of the tooth model, is usually performed only in the case of working teeth. In order for fixed work of pin work to be installed, a separate base member must be manufactured.

The base member is also made of partial bone, one side bone, and total tooth bone according to the shape of the working tooth. The base member corresponding to the tooth model is made by pouring casting stone into the rubber mold, and before the casting stone of the base member is hardened, Applying the separating agent to the bottom of the tooth model after the work is completed, the fixing pin exposed on the bottom of the tooth model is placed on the upper surface of the base member. When the tooth model is pressed, the exposed fixing pin is inserted into the base member and the teeth on the top of the base member Model 22 joins.

After a certain period of time, the base member is hardened and the base member separated from the mold is fixed to the articulator 10, and in order to be coupled to the articulator, the base member to which the dental model 10 is coupled and the antagonist are again installed. Gypsum (21, 21a) should be supplied to perform gypsum to check the occlusal state.

In this way, the working teeth and the opposing teeth coupled to the articulator reproduce the upper and lower mandibular occlusal structure of the patient's teeth by the up and down motions of the articulator. Workpiece fixed to articulator for the convenience of worker in the production of prosthesis is to perform the post-work by separating the cut tooth model from the articulator by cutting (Sawing) for the teeth that need treatment.

As post work, the prosthesis is made by waxing, investment, burning, and casting, and the finished prosthesis is completed by finishing work. This completed prosthesis is then placed on the dental model that needs to be fixed in the occlusal device so that the occlusal and chewing relationship of the patient's teeth can be confirmed by the up and down movement of the occlusal device.

As such, the articulator is necessary as an apparatus for confirming whether or not a prosthesis suitable for the tooth structure of the patient is manufactured after the production and manufacture of the prosthesis of the tooth that needs treatment in the patient's teeth.

As described above, the articulator is to reproduce the occlusal and mastication structures of the patient's teeth, and to make and confirm the optimal prosthesis or artificial teeth suitable for the occlusal structure and mastication of the patient's teeth, which are used in conventional laboratory In the case of articulators, the prior work before using them was very cumbersome and time consuming. In other words, in the case of the tooth model coupled with the base member, two pin fixing operations must be performed on the bottom of the tooth model being separated to prevent the flow of the tooth model being separated and combined. This has the disadvantage of eventually increasing the patient's cost burden.

And when the work to fix the teeth (22, 22a) by supplying the plaster (21, 21a) to check the occlusal state between the teeth (22, 22a) and the plate (19, 19a) The drawback was that it was very difficult to work with, and that it had to wait for the gypsum to harden, resulting in an inefficient time spent using articulators.

In particular, conventional articulators were made of metal and had semi-permanent durability. However, in order to reuse the articulators after use, the articulators had to be uncomfortable to stick to the articulators and to remove the tooth model of the cast stone cured from the plaster. It was large and heavy, so its handling was inconvenient.

In addition, in the case of the conventional articulator, the upper and lower arm units of the articulator to which the upper and lower dental models are coupled are fixed at the center position so as to maintain the horizontal state. It was inconvenient to imitate the teeth that fit the slope or occlusion and chew structure of the fit teeth.

The present invention was devised to solve the above-mentioned shortcomings, and it is convenient to use the existing articulator as it is, and to make plaster work to fix the dental model to be convenient, thereby saving work time and reducing the labor of workers by simplifying work in the laboratory. The purpose is to make it possible.

The present invention improves the structure of the plate connected to the model support installed integrally on the pedestal to fill the gypsum fixing the tooth model as it is. It is characterized by providing a model articulator.

The dental model articulator eliminates the effort of separating the dental model and the gypsum bonded to the articulator through a disposable plate, and reduces the time required for time-consuming plaster work, improving work efficiency and reducing labor Provides the effect of mitigating.
