Description

Articulator

The present invention relates to an articulator that can implement a mechanism similar to the jawbone movement of the human body made of a forward movement.

In general, the articulator is a device used to measure the occlusal state of teeth and gums and to make and diagnose dentures, crown restorations, and prostheses. .

In fact, the maxillary mandibular movement in the human body is the structure in which the mandible is moved without the maxilla being moved. The structure of most articulators is made by mimicking this type of maxillary mandibular movement. It is made based on the standard.

And the folding structure of the articulator is divided into an arcon condylar articulator with the condyle inducing part at the maxillary side, and a nonarcon condylar articulator with the condylar part in the mandible according to the position of the condyle element. In the case of the nonacon type, the frequency of use is high because it is a structure of an unregulated articulator that emphasizes reproduction of mandibular motion.

However, the problem of articulator is to reproduce the mandibular movement of the human body in order to locate the dental model in the condition that the tooth model is closest to the structure of the human maxilla and mandible. In human anatomy, the condyle has a spherical shape, so there are many differences from the working principle of the axis. Also, the up and down movement of the teeth is based on the combination of the position of the condyle and the muscle (low muscle) movement. As described above, if only the position of the condyle is the reference axis, the movement of the muscles is excluded, so an error may occur when measuring the upper and lower jaw movements.

In addition, in order to adjust the error range to form a variety of control means in the articulator to finely control the error, but in the case of the non-regulatory articulator can measure only the simple open and close occlusion means for adjusting the error separately There is no way to correct this error.

Therefore, when the occlusion is measured, the error becomes large, and eventually, there is a problem that post-processing is absolutely necessary in the state where the prosthesis is inserted into the patient.

In addition, such a conventional articulator is to fix the upper and lower mandible model while confirming the position of the occlusal plane by using an auxiliary means such as a rubber band or a laser in order to position the upper and lower mandibular models on the correct occlusal plane. There is a lot of difficulties in mounting the correct position by using, and there is a problem that a slight error occurs due to the thickness of the auxiliary means.

The upper and lower jaw movement structure of the upper and lower jaw is simple, but also to minimize the error of occlusion and to accurately mount the upper and lower jaw on the occlusal registration No. 10-0976044 (articulator) has been proposed.

The articulator disclosed in Korean Patent Publication No. 10-0976044 has a mandibular fixture 210 on which a mandibular model is mounted, and a maxillary fixture 110 on which a maxillary model is mounted, formed at the lower end of the maxillary fixture 110, as shown in FIG. It is folded up and down by the rotation shaft 130, the rotation shaft 130 is axially coupled to the engaging rod 220 formed on the lower fixing member 210, the lower fixing member 210 and the upper fixing member 110 of The column formed at the rear has the same vertical height, so that the rotational shaft 130 is positioned on the extension line of the occlusal plane α and the lower jaw 210 and the upper jaw 110 have a top, center around the pivot 130. It is folded and operated symmetrically downward, characterized in that the tangent β of the rotational motion of the maxillary model and the mandibular model abuts perpendicular to the occlusal plane α (the tangent β, the maxillary model and the mandibular model See FIG. 5).

However, the articulator configured as described above has a structure in which the maxillary stationary 110 is movable rearward, but is not moved forward by the hanger 220. On the contrary, since the jawbone movement of the human body is a forward movement, an articulator capable of implementing a similar mechanism is required.

It is characterized by.

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention will be described in detail.

As shown in Figures 2 to 5 articulator according to the present invention

Consists of the maxillary fixture 20 and the mandibular fixture 10 to be folded up and down by the pivot shaft 13 of the mandibular fixture 10, and by adjusting the horizontal degree of the mandibular fixture 10, the occlusal plane (α) is After setting, mounting the mandibular model 200 and the maxillary model 300 on the occlusal plane (α) is a structure that can ensure the arrangement relationship of the teeth.

Specifically, the articulator of the present invention includes a maxillary fixture 20 and a mandibular fixture 10.

The maxillary fixation stand 20 includes a maxillary fixation part 21, a lower curved support part 27, a locking jaw 22, and a guide part 23.

The mandible fixing 10 includes a mandible fixing part 11, an upper curved support part 14, a pivot shaft 13, and a spacer adjuster part 12.

And the spacing adjuster support portion 12 of the lower jaw fixing 10 is equipped with a spacing adjuster 40, the guide portion 23 of the upper jaw fixing 20 is provided with a return means.

In the maxillary fixing part 21 and the mandibular fixing part 11, the ivory model 300 and the mandible model 2000 are fixed with plaster, respectively.

The lower curved support part 27 of the maxillary fixture 20 extends from the rear of the horizontal maxillary fixing part 21 and is bent downward to support the maxillary fixing part 21, as shown in FIG. 3. The two are bent in pairs and at the end, the pivot shaft 13 is locked to support the pivot of the pivot shaft 13 so that the tip of the mandible fixing part 11 is open in the direction facing and is caught in the opposite direction. Hanging jaw 22 is formed.

The guide part 23 is mounted on the downward curved support part 27 and has a return means for returning to the position before the pivot shaft 13 is separated, and the locking step 22 of the downward curved support part 27 is provided. Both sides are connected to the formed portion, the intermediate portion is connected to protrude toward the front. In the middle of the protruding portion, a protruding wall 24 protruding downward is formed, and the protruding wall 24 is provided with a return means for returning to the original position before the pivot shaft 13 is separated.

Meanwhile, in FIG. 3, the guide part 23 is illustrated as being mounted on the upper side of the locking jaw 22, but may be mounted on the lower side. In this case, the rotating shaft 13 may be detached from the locking jaw 22. Guide (13).

The lower jaw fixing unit 10 is bent upwardly extending support portion 14 from the lower jaw fixing portion 11, the end of the rotation shaft 13 is formed.

And the spacer adjuster 12 extends from the rotation shaft 13 and is bent so that the front end is bent toward the same direction as the front end of the lower jaw fixing portion (11).

The return means is composed of a push rod 31 and a spring 32, the push rod 31 is capable of moving forward and backward in a penetrating and penetrating state of the axial wall 24 and one side is in contact with the rotation shaft (13). The spring 32 is fixed or in contact with the push rod 31, the other side to the protruding wall 24 in order to maintain the state that the push rod 31 is in contact with the rotation side (13). By the return means, the rotation shaft 13 of the lower jaw fixed base 10 is held by the locking jaw 22. And when moving the lower jaw 10 by the manpower forward pivot 13 is slightly (not completely out of the locking jaw 22), if the guide portion 23 is located below the locking jaw 22 Complete Departure) Departure can be done by twisting left and right. On the other hand, when the attraction force is released by the return means the rotating shaft 13 is caught while being in close contact with the inner surface of the locking step (22).
