Description

Tooth duplication molding apparatus {A plastic apparatus of tooth duplication}

The present invention is a dental replication molding apparatus, in particular a plate capable of vertical rotation on the upper surface of the base plate seated on the workbench, a plurality of rotary vise is mounted side by side on the plate is possible to rotate horizontally, coupled to each of the rotary vise rotates It consists of a fixed vise that is integrally rotated with the vise, which is guided from the form of a sample tooth attached to one fixed vise and mills the denture molding member attached to another fixed vise, wherein the plate and the rotary vise are positioned appropriately. And it relates to a tooth replication molding apparatus capable of precise milling operation by moving at an angle.

Tooth duplication usually refers to the creation of artificial teeth or dentures based on specimen teeth, or the same type of dentures as sample teeth to produce implant teeth, and then the dentures based on dentures. Also, denture or artificial tooth refers to an artificial tooth or a prosthesis that artificially replaces a natural tooth when it is missing. Such dentures include both local teeth used when one or more teeth are missing and total dentures used when the entire tooth is missing or multiple teeth are missing.

As a material of the existing dentures, metals such as gold were mainly used. However, they were problematic because not only were unnatural and aesthetically inferior, but also inevitably oxidized in nature. Ceramics, in particular zirconia, are widely used as biomaterials to replace these existing metal materials. Zirconia is a form in which zirconium is already oxidized and does not cause the above-mentioned oxidation problem. In addition, in the tetragonal state of high temperature quasi-stable stability, the strength and hardness are very high, light transmittance, and the color can be adjusted according to the added ingredients, which can be almost similar to actual teeth.

In general, the production of dentures including zirconia is performed by fabricating a sample tooth, and then milling the block-like zirconia for cutting and surface grinding before sintering with reference to the sample tooth, followed by sintering at about 1500 ° C. The process of obtaining is progressed sequentially. Since zirconia has a size reduction of approximately 20-30% after sintering, the milling operation of the dental work must be processed by 20-30% larger than the actual size. This is a very difficult process even for a skilled worker, not only requires a lot of work time, but also has a problem that it is very difficult to obtain a precise form.

The present invention has been made to solve the above problems, an object of the present invention is to be able to expand the denture molding member to a certain ratio size for the sample teeth and to perform the same precision milling in terms of shape Of course, there is provided a dental cloning molding apparatus capable of milling denture molding members quickly and precisely even if they are not highly skilled workers.

In order to achieve the above object, the present invention is a dental cloning molding apparatus during the milling operation in a state in which a pair of dental teeth and a denture molding member for milling in the same form as the teeth of the teeth in the form of teeth. In the dental replication molding apparatus for moving the sample tooth and the denture molding member to a desired position, the both ends are connected to a plurality of supports attached to the upper surface of the base plate seated on the worktable to rotate vertically, but penetrates vertically A plate having a plurality of openings formed therein and a stepped portion formed at an edge of the opening; A rotating vise seated horizontally on the stepped portion, wherein an opening penetrating up and down is formed in the central portion, and a stepped portion is formed on the inner wall of the opening; It is rotated integrally with this rotary vise in a state of being fixed to the stepped portion, and comprises a fixed vise is fixed to the sample teeth and denture molding member, the first to the plate to fix the rotary vise at a desired angle; 2 fixing means are provided.

Guide grooves for guiding the second fixing means in contact with the rotary vise are formed in the central portion of the side of the rotary vise, and the guide grooves are equally spaced along the direction of rotation of the rotary vise so that the second fixing means can be fitted therein. A plurality of fixing grooves are formed. In addition, a scale indicating a rotation angle is displayed on the upper surface of the rotary vise at equal intervals with the plurality of fixing grooves, and a reference line is formed on the upper surface of the plate to check the rotation angle of the scale.

The dental cloning molding apparatus according to the present invention can work while moving the sample tooth and the denture molding member to a desired position finely, so that the denture molding member can be expanded at a constant rate with respect to the sample tooth even without a highly skilled worker. Of course, there is an advantage that can be precise milling in terms of shape, and there is an effect that can significantly reduce the work time. In addition, since the present invention can quickly perform precise work with a simple configuration, there is an economically advantageous effect away from the dependency of the existing expensive equipment.
