Description

Technical Field [0001] The present invention relates to an articulator having a reference member for mounting an upper-

The present invention relates to an articulator capable of realizing a mechanism similar to a movement of the jawbone of a human body in forward movement, and more particularly, to a method of attaching a model of an articulator using an anatomical standard of an oral system, And to an articulator capable of measuring the positional relationship in the arrangement of the upper teeth used and measuring the long axis of the upper anterior teeth.

In general, the articulator is a device used to measure the occlusal state of the gums and to manufacture and diagnose dentures, crown restorations, and prostheses, and to reproduce the relative positional relationship between the jaw and teeth and the mandibular movement mechanically .

In fact, in the human body, the upper and lower mandibular movements are structures in which the maxillary bone does not move and the mandible moves. Most of the articulators' structures mimic the shape of the upper and lower mandibular movements. As a reference.

The folding structure of such an articulator is divided into an arcon condylar type articulator in which the over-induction portion is located at the upper side and a nonarcon condylar-type articulator in which the over-induction portion is located at the lower- In the case of the acorn type, the frequency of use is high because it is the structure of the non-adjustable articulator that emphasizes the representation of the mandibular motion.

However, the problem of such an articulator is to reconstruct the mandibular movement of the human body in order to position the upper and lower tooth models in the condition that the tooth model is closest to the structure of the maxilla and mandible of the human body. The anatomical view of the human anatomy is that the condylar shape is very different from the working principle of the shaft and the up and down movements of the teeth are made by the combination of the position of the condyle and the muscle (masticatory) In the case of using only the position of the condylar as the reference axis as described above, since the movement of the muscles is excluded, an error will occur when measuring the maxillary and mandibular movements.

In order to adjust the error range, a variety of adjusting means is formed on the articulator to control the error. However, in the case of the non-adjustable articulator, only a simple open / close occlusion can be measured. There is no way to correct this error.

Therefore, there is an error in measuring the occlusion, and in the end, there is a problem that post-processing is necessarily required in a state where the prosthesis is inserted in the patient.

In addition, such a conventional articulator fixes the upper and lower models while confirming the position of the occlusal plane by using an auxiliary means such as a rubber band or a laser to position the upper and lower models on the correct occlusal plane. There is a problem in that it is difficult to mount it at the correct position by using it, and that a minute error is caused due to the thickness of the auxiliary means itself.

In this regard, Registration No. 10-0976044 (Articulator) has been proposed in order to simplify the movement structure of the upper and lower mandibular maxilla and mandible while minimizing the error of occlusion and accurately mounting the maxilla and mandible on the occlusal surface.

As shown in FIG. 1, the articulator disclosed in Japanese Patent Application No. 10-0976044 includes a lower fixture 210 on which a mandibular model is mounted and an upper fixture 110 on which an upper model is mounted is formed at a lower end of the upper fixture 110 The pivot 130 is pivotally coupled to the pawl 220 formed on the mandrel retention base 210 and is coupled to the upper and lower ends of the mandrel retention base 210 and the upper retention base 110. [ The column formed on the rear side has the same vertical height so that the pivot axis 130 is positioned on the extension line of the occlusal plane alpha so that the upper and lower pivotal supports 210 and 110 rotate about the pivot axis 130, And the tangent line of the rotational motion of the maxillary and mandibular models is perpendicular to the occlusal plane alpha (tangent line (?) And the maxillary and mandibular models 5).

However, the articulator configured in this manner has a structure in which the upper retractor 110 can move backward but can not be moved forward by the retractor 220. On the other hand, since the jawbone motion of the human body is a forward motion, an articulator capable of implementing a similar mechanism is required.

On the other hand, the method of attaching the model to the articulator includes a method using arbitrary attachment method, face bow transfer, and the like.

The arbitrary attachment method (average gingival attachment method) is attached to the maxillary model of the articulator in the eyes of the surgeon or by using an apparatus such as an elastic band, so that there may be an error in the horizontal positional relationship between the human body and the symmetrical relationship.

In addition, the present invention utilizes a reference member made up of the mounting jig (60) and the reference plane member (50) when the upper model (300) of the articulator is installed to reduce the horizontal positional relationship and the error of the symmetrical relationship.

Specifically, the articulator of the present invention includes an upper fixture 20, an upper fixture 10, and a reference member.

The upper fixture 20 includes an upper fixing part 21, a lower curving supporting part 27, a locking step 22 and a guide part 23.

The mandibular fixture 10 includes a mandibular fixation part 11, an upper bending support part 14, a pivot 13 and a gap adjuster support part 12.

A gap adjuster 40 is mounted on the gap adjuster support portion 12 of the mandibular support 10 and a return means is provided on the guide portion 23 of the maxillary fixture 20.

The ivory model 300 and the mandible model 2000 are fixed to the upper and lower portions 21 and 11, respectively, by gypsum.

The lower curved supporter 27 of the upper fixture 20 is configured to extend from the rear of the horizontal upper fixture 21 and to bend downward to support the upper fixture 21. As shown in Fig. 3, Two pairs are bent in a pair and the rotary shaft 13 is hooked to the end of the rotary shaft 13 for supporting the rotary shaft 13 so as to be opened in the direction in which the distal end of the mandible fixing part 11 is oriented, (Not shown).

The guide portion 23 is provided with a return means which is mounted on the downward curved support portion 27 and returns to a position before the rotation shaft 13 is released. Both sides are connected to the formed portion, and the intermediate portion is connected so as to protrude forward. A protruding wall 24 protruding downward is formed at an intermediate portion of the protruding portion. The protruding wall 24 is provided with a returning means for returning the protruding wall 24 to its original position before disengaging the rotating shaft 13.

3 shows that the guide portion 23 is mounted on the upper side of the latching jaw 22 but can also be mounted on the lower side. In this case, when the rotation shaft 13 is detached from the latching jaw 22, (13).

In the mandibular fixture 10, the upper curved support portion 14 is extended from the mandibular fixing portion 11 and bent, and a rotary shaft 13 is formed at the end thereof.

The gap adjuster support portion 12 is extended from the rotation shaft 13 and is bent so that its tip end is directed in the same direction as the direction of the distal end of the mandible fixing portion 11. [

The restoring means is composed of a plunger 31 and a spring 32. The plunger 31 penetrates through the shaft wall 24 and is allowed to move forward and backward while passing through the shaft wall 24. One side of the plunger 31 contacts the pivot shaft 13. The spring 32 is fixed or abutted to the push rod 31 at one side and the other side to the projecting wall 24 in order to keep the push rod 31 in contact with the pivotal side 13. The rotation shaft 13 of the mandibular fixture 10 is retained by the returning means to the stopping jaw 22. When the mandibular holder 10 is moved forward by a force, the pivot 13 is not completely removed from the engaging jaw 22 when the guiding portion 23 is positioned below the engaging jaw 22 It is possible to escape by twisting left and right. On the other hand, when the attraction force is released, the return shaft 13 is engaged with the inner side surface of the engaging jaw 22 by the returning means.

The distance between the mandibular fixation unit 11 and the maxilla fixation unit 21 is changed according to the rotation of the rotary shaft 13 and thus the distance between the one side of the interval adjuster support unit 12 and the one side of the guide unit 23 A gap adjuster 40 for adjusting the gap between the mandibular fixation unit 11 and the maxilla fixation unit 21 is installed on the gap adjuster support unit 12 .

The reference member is composed of a mounting jig 60 and a reference plane member 50. The mounting jig 60 is mounted on the lower fixture 10 and is made of a transparent material, And is inserted and fixed to the mandibular fixing part 11 through the flange part 64 which is provided on the upper part of the insertion part 64a and which is wider than the outer peripheral face of the insertion part 64a. Further, when the use of the mounting jig 60 is completed, it can be separated. A support column 63 is provided at an upper portion of the flange portion 64 and a flat plate 61 is provided at an upper portion of the support column 63. An upper surface of the flat plate 61 is connected to the rotation shaft 13 And a plurality of reference holes 61a for mounting the reference pin 62 for mounting the upper model 300 are formed on the front portion of the scale. And an insertion hole 61b for mounting the reference plane member 50 and a cutout 61c for preventing the interference of the plunger 31 are formed on the rear side. Here, since the set upper surface area in which the insertion hole 61b is formed (for example, in the vicinity of the upper surface on which the insertion hole 61b is formed) is flat and the remaining upper surface area is formed in a depressed curved surface shape, It is easy to see. The reference pin 62 is provided to serve as a reference of the tangent line β and the corresponding insertion hole 61b of the insertion hole 61b having a distance from the rotation center is inserted.

The reference plane member 50 is installed in the insertion hole 61b to obtain a HIP plane and is spaced apart from the upper surface of the mounting jig 60 by a predetermined distance and a hamular a first frame 51 having a hole 51a formed therein and a hole 51a inserted into a hole 51a of the first frame 51. The hole 51a is formed in the first frame 51, The present invention relates to an articulated musical instrument and a musical instrument which are provided on both sides of the first frame 51 and which are orthogonal to the first seat 54, And a stopper 55 which is engaged with the first frame 51 and is movable in a sliding manner and fixes the first frame 51. The stopper 55 is inserted into the insertion hole 61b The second seating portion 54 and the second seating portion 52 are spaced apart from the upper surface of the mounting jig 60, It comprises a frame (56). The upper ends of the first and second seating portions 54 and 52 are parallel to the upper surface of the mounting jig 60. The stopper 55 slidably moves the first frame 51 with respect to the second frame 56 when adjusting the distance between the teeth of the pivot shaft 13 and then moves the first frame 51 Fixed.

Hereinafter, the operation of the main part of the articulator according to the present invention and the process of mounting the upper model 300 on the articulator will be described.

The rotating shaft 13 is in tight contact with the inner surface of the engaging jaw 22 by the spring 31 of the return means provided on the stone axial wall 24 and the spring 32 and is held in a fixed state. Then, when the mandrel 10 is moved forward by the force, the pivot 13 is slightly released from the pawl 22. In addition, it can be disengaged while being twisted to the left or right according to the human force, and the rotating shaft (13) comes in contact with the inner side surface of the engaging jaw (22)

As described above, the articulator according to the present invention can move forward, unlike the conventional art, so that a mechanism similar to the motion of the jawbone of the human body in the forward movement can be realized.

The upper surface of the gap adjuster support portion 12 and the lower surface of the projecting wall 24 of the guide portion 23 are normally in contact with each other. However, when the gap adjuster 40 (which may be a normal bolt) The spacing distance between the gap adjuster support portion 12 and the protruding wall 24 of the guide portion 23 is adjusted according to the fastening state of the fastener 40 so that the limit angle of the mandibular fastener 10 can be finely set.

5 shows a procedure of mounting an upper model on the articulator of the present invention. 5, the mounting jig 60 is mounted on the inner circumferential surface of the mandibular fixing part 11 while the upper fixing part 21 is tilted, and the reference plane member (not shown) is inserted into the insertion hole 61b of the mounting jig 60 50 are inserted. At this time, the upper end of the first seating portion 54 and the second seating portion 52 are spaced apart from the upper surface of the flat plate 61 of the mounting jig 60 by about 7 mm, which is usually a distance between the hip plane and the occlusal plane Is about 7 mm.

The incisive papilla of the next upper model 300 and the hamuiar notch located behind the last molar of both the maxilla and the maxilla are seated on the first and second seats 54 and 52, respectively . At this time, since the position of the incisor papilla is different according to the person, the first seating portion 54 is adjusted and seated. The upper jaw model 300 is fixed to the upper fixing part 21 and the tooth arrangement is completed and the mounting jig 60 to which the reference plane member 50 is connected after the upper fixing part 21 is tilted is inserted into the lower jaw fixing part 11), and then the mandibular model is fixed to the mandibular fixation part 11 based on the maxillofacial model 300.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications, and variations will readily occur to those skilled in the art without departing from the spirit and scope of the invention. Therefore, it should be understood that the disclosed embodiments are to be considered in an illustrative rather than a restrictive sense, and that the true scope of the invention is indicated by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof, .
