Abstract

Disclosed are an upper jaw adjuster unit and a dental articulator for an operation for correcting a jaw joint using the upper jaw adjuster unit. The upper jaw adjuster unit and the dental articulator including the upper jaw adjuster unit adjust the left, right, forward, and rearward angles of an upper jaw model, and the rotational angle and position thereof. Furthermore, the upper jaw adjuster unit and the dental articulator freely adjust the height of the upper and lower jaw models. Accordingly, an occlusion structure, which is naturally movable like a jaw joint of a human, is formed, to thereby ensure the occlusion accuracy of an operation for correcting a jaw joint.

Description

Maxillary control unit and dental articulator for jaw arthroplasty using the same

The present invention relates to a maxillary control unit and a dental articulator applying the same, and in particular, the maxillary and mandibular models can freely adjust the occlusal relationship as human joints, thereby ensuring the accuracy of occlusion through real simulation, thereby It relates to a maxillary control unit for easily performing arthroscopic surgery and a dental articulator for jaw arthroplasty using the same.

As the position of the maxilla and mandible is misaligned, jaw disorders such as the jaw joints occur, which is rarely noticed by oneself. Most of them are found by dentists and dental technicians when designing dentures and the like.

In particular, when the deviation between the maxillary and mandible exceeds the tolerance, it is accompanied by pain enough to interfere with the daily life, so if left untreated, the condition may become more severe and may have a great effect on the facial beauty. Therefore, when the occlusal problem of the jaw joint is found, it is preferable to perform the occlusal treatment early. Such occlusion treatment is made through the process of occlusal articulation by creating a model of the maxillary and hanak through the device called articulator.

Such a conventional articulator fixes the maxillary and mandibular models on the upper and lower portions of the support frame, and has a structure capable of recognizing the occlusal state of the maxillary by pinching and opening the support frame.

However, such a conventional articulator can not achieve the natural motion like the jaw joint of a real person, such as the front and rear left and right angle adjustment, front and rear left and right movement control and rotation control in the upper part of the mandible model as a reference.

Therefore, the occlusal process of the maxillary model and the mandibular model is difficult, as well as the natural motion is difficult, there was a problem that the accuracy in the occlusion process.

The present invention is to solve the conventional problems as described above, by adjusting the height of the maxillary model and the mandible model as well as the front and rear, left and right angle, rotation angle and position of the maxillary model, it moves naturally like the human joint The occlusal structure ensures the accuracy of occlusion through actual simulation, and provides the maxillary control unit and dental articulator applying the model adjuster to allow precise correction of jaw arthroplasty from the accuracy of the occlusion. There is a purpose.

The maxillary control unit for adjusting the position of the maxilla is applied to the dental articulator for achieving the above object, the fixing plate fixed to the maxillary support frame of the articulator; An angle adjusting plate positioned to have a gap with a lower portion of the fixing plate; A front and rear angle adjuster which is screwed vertically to the upper portion of the angle adjusting plate through the fixing plate, and adjusts the height of the front of the angle adjusting plate at the upper portion of the upper support frame; A left and right angle adjuster which is screwed vertically to both rear sides of the angle adjusting plate through both rear sides of the fixing plate to adjust the left and right heights of the angle adjusting plate at the top of the fixing plate; A left and right adjuster which slides to the left and right to slide corresponding to the lower part of the fixing plate; A front and rear controller which slides back and forth to slide correspondingly to the lower part of the left and right regulators; And a rotation controller coupled to a lower portion of the front and rear controller to adjust the rotation angle and to which the maxillary height controller is attached. Characterized in that comprises a.

In addition, the dental articulator for jaw arthroplasty for achieving the above object is a mandible support frame which is extended to the upper in the rear divided state is provided with a lower jaw support for fixing the fastening portion and the front upper mandible; A maxillary support frame which is fastened to the fastening part of the mandatory support frame and rotates forward and downward, and has a maxillary support for fixing the maxillary model; A support bar inserted through the front upper portion of the upper support frame so that the length is adjusted, and the inserted end is in contact with the front upper surface of the lower support frame; A mandatory height adjustment plate between the mandatory support frame and the mandible support part correspondingly attached to at least one or more by a magnet disposed therein to adjust the height of the mandible model; A fixed plate fixed to the lower portion of the upper support frame; Positioned to be spaced apart from the bottom of the fixing plate, the front and rear angle adjustment of the maxillary model according to the front height adjustment in the state fixed to the lower part, the left and right angle adjustment, left and right position adjustment, front and rear position adjustment and Maxillary control unit for adjusting the horizontal rotation angle; And a maxillary height control plate between the maxillary control unit and the maxillary support portion corresponding to at least one or more by a magnet disposed therein to adjust the height of the maxillary model; Characterized in that comprises a.

As described above, the present invention allows the maxillary model that corresponds to the reference mandibular model to move naturally as if it were a real human joint (especially, by accurately measuring the anteroposterior and rearward angles (inclined) of the maxillary model). There is an advantage to ensure the accuracy and reliability of the surgery.
