Problems solved by technology

This method tries to restore the patient's muscular ligaments by wearing a splint, raising the vertical distance, and removing occlusal interference. They believe that the patient has the ability to find the neutral relationship and stabilize in this position, but there are three main problems with this method. think clearly
1) The unexplained elevation of the vertical distance is very unfavorable to the patient's originally disordered muscles, which will stretch the length of the masticatory muscles and cause more hyperactivity of the muscles. The discocondylar relationship is due to the opening of the vertical distance and the function of the masticatory muscles. become unpredictable
2) Although the patient's symptoms can be relieved in a short period of time, and the occlusal position seems to be "stable", but there is no further evidence-based medicine to prove that the position is correct, and when the patient removes the stable occlusal splint, especially for adults, the occlusal position is almost It will immediately return to the original state, that is, the role of stabilizing the bite plate is largely equivalent to muscle relaxation, but it tries to let the decompensated oral and jaw system "find" its own positioning, which is obviously Unrealistic; 3) Assuming that the position found using the stable occlusal plate is correct, but once the stable occlusal plate is removed, how can we be sure that the occlusal position has not changed and is consistent with the initial one during the tooth movement? How to accurately realize that the final cusp crossing position is located in the final median relationship position? 2. Make a repositioning occlusal plate, and try to perform orthodontic treatment in this occlusal position
This method requires a strong knowledge of alignment to confirm that the alignment is correct, luckily we can do it, but how to achieve this alignment is tricky
Many foreign scholars believe that even in adult patients, as long as the symptoms are relieved and the inflammation does not continue to develop, the mission of repositioning the occlusal splint is over, and the patient can directly undergo orthodontic treatment; Combined method to precisely control the position, but there is no report

Embodiment 1

[0030] Embodiment 1: see figure 1 , a temporomandibular joint orthodontic system, including an occlusal analysis system, a mandibular motion facebow 1, a fully adjustable jaw frame and a repositioning occlusal plate, and the mandibular motion facebow 1 performs dynamic data collection and transfers the dynamic data to Fully adjustable upper jaw. The fully adjustable jaw frame is composed of an upper support 2, a lower support 3, and a support 4. The upper end of the support 4 is rotationally connected with the upper support 2, and the lower end of the support 4 is fixedly connected with the lower support 3. The upper support The seat 2 and the lower support 3 are respectively provided with a retractable frame ring 5, and the upper and lower jaw models are arranged on the frame ring 5, and a cutout with a scale is also provided between the upper support 2 and the lower support 3. Guide pin and cutting guide disc7.

Abstract

The invention discloses a temporomandibular joint deformity correction system and a method for making a personalized deformity correction device. The method comprises 1, analyzing an occlusal function through an occlusion analysis system to determine an occlusion position, 2, preparing original upper and lower jaw models according to the occlusion analysis system and re-positioning an occlusion plate through patient wearing with the original upper and lower jaw models, 3, carrying out re-examination on the patient each month, 4, after re-examination, determining whether the occlusion position is correct and carrying out deformity correction, 5, stabilizing the occlusion position and carrying out a tooth arrangement test, and 6, producing the personalized deformity correction device according to the tooth arrangement model after the tooth arrangement test. Compared with the prior art, the system realizes personalized tooth arrangement through combination of an adjustable frame, function analysis and projective measurement analysis according to the patient's skull surface type, utilizes a covering material to precisely control the position of the occlusion position, prevents occlusion position change, evaluates the tooth movement amount in a visual state through 3D data scanning before and after tooth arrangement and provides good deformity correction treatment guidance for later treatment.

Description

technical field [0001] The invention relates to a medical device, in particular to a temporomandibular joint orthodontic system and a method for making a personalized appliance. Background technique [0002] There is no report about how to accurately realize the established occlusal position. The traditional method is: 1. Wear a stable occlusal splint, and start or continue orthodontic treatment after the patient's symptoms are relieved and the occlusal position is "stabilized". This method tries to restore the patient's muscular ligaments by wearing a splint, raising the vertical distance, and removing occlusal interference. They believe that the patient has the ability to find the neutral relationship and stabilize in this position, but there are three main problems with this method. Think clearly. 1) The unexplained elevation of the vertical distance is very unfavorable to the patient's originally disordered muscles, which will stretch the length of the masticatory muscl...
