Description

Disposable Tooth Type Articulator for Implant Prosthetics {DISPOSABLE ARTICULATOR FOR THE DENTAL MODEL POSSIBLE IMPLANT PROSTHESIS}

The present invention relates to a dental model articulator, and more particularly, to a disposable dental model articulator capable of implant prosthesis.

The most common method of treating tooth decay or damaged teeth is to remove tooth decay, prosthetic work, or extract teeth and plant artificial teeth (implants).

To perform prosthetic work or replacement with artificial teeth, dental teeth are usually sent to the dental laboratory by making negative patterns for the upper and lower gums and teeth of the patient. In the dental laboratory, dental plaster is injected into the negative teeth. Make

Such a tooth model may be divided into a working value and a confrontation opposite to the working value according to the correlation of the 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, and the device designed to reproduce the upper and lower mandibular structures corresponding to the tooth structure of the patient is a dental model articulator.

The dental articulator is a kind of dental model support that holds the dental model (working teeth and clam teeth) to facilitate the follow-up work on the dental model.It is equipped with the dental model and reproduces the jaw joint movement. This is the device for processing the prosthesis to be compatible with existing teeth when the actual prosthesis is inserted.

Articulators have been developed in many ways, from simple structures to complex and sophisticated instruments, and are generally composed of a frame having a vertical opening and closing structure and a fixed base for fixing work and antagonists to the frame.

The antagonist can simply fix the lower surface of the antagonist flattened with adhesive to the stationary base of the articulator, but the work unit can be combined with the stationary base of the articulator to separate the lower surface flattened by the grinder. So that it can be separated if necessary to facilitate prosthetic work. In this case, pin work should be performed on the lower surface of the work piece so that the work piece is fixed at the correct position when the work piece is attached to or removed from the fixed base.

The pin work is usually done by drilling a groove into which the fixing pin will be inserted into the bottom of the finished tooth model (working tooth) and applying the adhesive on the top of the fixing pin to the machined groove to fix the upper part of the fixing pin and expose the lower part. do.

After the pin work is completed, the work piece is attached to the fixing base of the articulator with dental plaster. In other words, pour dental plaster on the top of the fixed base and apply a separating agent to the bottom of the tooth model after the pin work is completed before the plaster hardens for a certain period of time so that the fixing pin exposed on the bottom of the tooth model is located on the top of the base. When the dental model is pressed, the exposed fixing pin is inserted into the dental gypsum on the upper part of the fixing base, and the dental model is coupled to the upper end of the base, and may be separated from the fixing base as necessary.

And the working value fixed to the articulator for the convenience of the operator when manufacturing the prosthesis can be performed by separating the cut tooth model from the articulator by cutting (Sawing) for the teeth that need treatment.

However, the above-described dental model articulator has a hassle to drill a groove in a portion where the fixing pin is to be inserted into the lower portion of the working tooth using a drill when working on the working tooth.

In recent years, the use of disposable dental model articulators is also relatively low in price and excellent in performance. However, until now, disposable dental articulators can only be used in the production of general dental prostheses, but not in implant prostheses.

The compartment 26 in the main body 20 may be implemented by spaced apart from the front and rear by partitions 28 extending downward from the bottom of the upper plate 22.

In the present invention, the partition wall 28 extends directly below the pinhole 24 and forms a pinhole extension portion 30 having a space portion 30a to accommodate the metal pin 13, and the left and right sides of the pinhole extension portion 30 are formed. It consists of the compartment member 32 extended from an end to the inner wall of the main body 20. As shown in FIG.

The lower end of the space part 30a of the pinhole extension part 30 forms a locking end 30b so that the metal pin 13 is locked when the metal pin 13 is inserted. The metal pin 13 has a narrow lower end and a larger diameter toward the top, and the metal pin 13 fitted into the pin hole 24 of the upper plate 22 of the main body 20 has a locking end 30b of the pin hole extension 30. Are easily inserted. And when pressing the upper portion of the metal pin 13, which is caught on the locking end 30b, the locking end 30b is separated and the lower portion of the metal pin 13 protrudes out of the space portion 30b of the pinhole extension 30. It is pressed and fixed to the space portion 30a of the pinhole extension portion 30 by the diameter that increases toward the upper portion.

The lower portion of the metal pin 13 protruding outside the space portion 30b of the pinhole extension portion 30 is subsequently fused by the dental plaster 64 to the upper plate 22 of the main body 20 of the fixed base 10. The dental plaster (60) is fixed to the dental plaster (64) and the dental plaster (64) forming the body with the dental model (60) and the dental model (60) is the first plate 22 of the main body (20) for the first time. To stably separate from, this is achieved by pressing the bottom of the protruding metal pin 13.

In the process of fixing and fixing the dental model 60 by pouring dental plaster 64 on the upper plate 22 of the main body 20, the metal pins 13 are formed on the upper plate 22 of the main body 20. It can be inserted into everything, but sometimes only the part you need is selected. In this case, the locking end 30b of the pinhole extension part 30 does not insert the metal pin 13, so when the dental gypsum 64 is poured onto the upper plate 22 of the main body 20, the dental gypsum 64 ) Serves to prevent the pinhole extending portion 30 from leaking out through the space portion 30a of the pinhole extending portion 30.

The compartment member 32 constituting the partition wall 28 together with the pinhole extension portion 30 extends from the left and right ends of the pinhole extension portion 30 to the inner wall of the lower portion and the main body 20. The lower inner side of the compartment member 30 is formed to be rounded, so as to separate the tooth model 60 coupled to the upper plate 22 of the main body 20 when pressing the lower portion of the metal pin 13 with a finger or the like. 13) It is easy to press the lower part and also reduce the pressure applied to the finger.

The lower cover 40 is coupled to the lower portion of the main body 20. The lower cover 40 is coupled to the lower part of the main body 20 to close the lower part of the open main body 20 and to close the compartments 29 provided by the partition walls 28 in the main body 20. Has the function.

Therefore, the lower cover 40 is preferably formed in accordance with the shape of the lower end of the partition wall 26 in the main body 20 so that the adjacent compartments 29 are blocked from each other. In the present invention, the partition wall 26 is formed. The vertical wall 42 and the protruding piece 44 are extended upwardly to correspond to the lower end shapes of the compartment member 32 and the pinhole extension portion 30 to constitute.

A metal pin receiving hole 44a is formed in the protruding piece 44 of the lower cover 40 so that the metal pin 13 partially protrudes out of the space 30b of the pin hole extension 30. To accommodate the lower part.

In the present invention, the lower cover 40 must be coupled to the lower portion of the main body 20 so as to be clogged between adjacent compartments 26 when the implant prosthetic work, there is no problem in the work even if not combined in the general prosthetic work. .

Meanwhile, in order to fill the dental gypsum 64 inside the compartment 26 of the configuration, as shown in FIG. 4, the upper plate 22 part of the upper portion of the upper part of the compartment 26 is first drilled with a drill for dental pores ( 26) Let the top open. Therefore, in constituting the upper plate 22 of the main body 8, it is preferable to form the crushed surface portion 34 so that the upper portion of the compartment 29 can be easily drilled with a dental pore drill or the like. The crushed surface portion 34 is formed so that the partition can be easily seen by forming a square protrusion line 36, the thickness (t) of the crushed surface portion 34 is preferably formed to be thinner than the thickness of the outer side of the crushed surface portion 34 Do.

A step 38 is formed along the circumference of the main body 20 of the fixed base 10, and the top cover 50 which is opened up and down is coupled to the step 38.

The upper cover 50 is provided with a mold of dental plaster 64 which is filled to fix the dental model 60 on the upper part of the main body 20 as it is coupled to the upper step 38 of the upper part of the main body 20. It is formed higher than the height of (38).

The frame provided by coupling the upper cover 50 to the upper part of the main body 20 makes the outer peripheral surface of the dental gypsum 64 to be filled in the mold afterwards uniformly and firmly coupled to the upper part of the main body 20. It facilitates the joining work. The upper cover 50 may be removed when the fixing of the dental model 60 is completed on the main body 20 by the dental gypsum 60.

The fixed base 10 of the above configuration is coupled to the coupler 6 rotatably coupled to both ends of the arm member 4. Coupling sphere 6 may be formed to form a coupling protrusion (6a) and the assembly groove 39 is formed on one side of the main body 20 of the fixed base (10).

In this case, one of the couplers 6 coupled to both ends of the arm member 4 couples the work tooth fixing base 10 to the other coupler 6 and the opposite coupler fixing base ( 12) can be combined, and both of the couplers 6 can be used by combining the working tooth fixed base 10 or the antagonist fixed base 12.

Now with reference to Figures 5 and 6 will be described the process of coupling the dental model 60 to the fixed base 10 during the implant prosthetic operation.

First, the upper cover 50 is coupled to the step 38 formed on the upper plate 22 of the main body 20 of the fixed base 10 to prepare a mold to be filled with dental plaster, and the metal pin 13 in the pinhole 24. Insert).

The metal pin 13 may be selectively inserted in consideration of the position of the tooth requiring prosthetic work, and may be inserted into all pinholes 24 in some cases.

The metal pin 13 inserted into the pinhole 24 presses an upper portion thereof to partially protrude the lower portion of the metal pin 13 below the pinhole extension portion 30, and the metal pin 13 extends the pinhole extension portion 30. Make sure the paper is fixed.

The lower part of the main body 20 is fastened to the compartments 26 to be blocked by each other by fastening the bottom cover 40, and at the position where the implant wrap analog 67 is to be placed, the fracture surface part 34 is drilled with a drill for dental laboratories. (26a) Let the top open.

After that, the dental gypsum 64 is filled in the mold on the upper portion of the main body 20, but the dental gypsum 64 is filled in the open compartment 26a through the crushed surface part 34.

After the dental gypsum 64 is filled in the frame and the compartment 26a of the upper part of the main body 20, the dental model 60 is placed on the filled dental gypsum 64 to be fused and fixed with the dental gypsum 64. In addition, an implant wrap analog 67 is implanted in a compartment 26a having an open top, that is, a compartment 26a filled with dental plaster so as to correspond to a situation of a fixture implanted in an alveolar bone of an actual person.

 In this case, the gypsum does not flow unnecessarily into the other compartment 26 which does not inject the dental gypsum 64, thereby preventing waste of material, and also the dental gypsum 64 injected into the compartment 26a and Implant wrap analog 67 is protected by partition 28 to ensure robustness.

When the dental gypsum 64 is hardened in the above state, a subsequent operation for making an optimal artificial tooth (implant) 70 is performed by cutting the drill with respect to the dental model 60 as shown in the photograph of FIG. 6. You will proceed.

The process of coupling the tooth model (working tooth) 60 to the fixed base 10 during the general prosthetic work is similar to that of the implant prosthetic work, but there is no reason for implanting the implant wrap analog (67), so that the fracture surface (34) is drilled through the compartment. (26) It is not necessary to work to open the upper part. In addition, the lower cover 40 does not have to be fastened.

As described above, the disposable dental model articulator 2 capable of manufacturing the implant prosthesis of the present invention is inserted into the metal pin 13 in the preformed pinhole 24, which is cumbersome to drill the lower part of the dental model 60 as before. The labor of the pin work, and can be applied at the time of implant prosthesis production by allowing the implant wrap analog 67, as well as the production of general dental prostheses.
