Technical Field

The invention relates to a jaw plate manufacturing device and method for malocclusion orthodontic, and belongs to the technical field of auxiliary equipment for orthodontic operation.

Background

Malocclusal deformities not only affect the normal development of oral and facial tissues, hampering the health of teeth and periodontal tissues, but also affect the function of the oral cavity and the beauty of the face. When malocclusion is serious, the chewing function is seriously reduced, which causes dyspepsia and gastrointestinal diseases and damages to health. Partial malocclusion deformity hinders pronunciation and surface shape, affects normal friend making and social contact, and even causes serious psychological burden.

Malocclusion conditions are different, which cause the appearance of the jaw and the function of teeth to be obstructed in different degrees, and the key is to correct teeth in time. At present, a method and a device capable of accurately simulating, analyzing and simulating the upper and lower occlusion correction relationship are urgently needed. The method and the device can help a doctor to determine the size to be corrected through the dental model and the jaw plate so as to determine a treatment scheme, and can repeatedly simulate the effect after treatment.

The conventional operation flow of the existing maxillofacial surgery aiming at malocclusion orthodontics is as follows:

1. enabling the malocclusion patient to bite the standard jaw plate to manufacture an original occlusion jaw plate;

2. taking basic orthodontic size according to the difference of upper and lower dental marks of the original jaw plate, and leaving for guidance for operation

3. Scanning the upper and lower tooth bodies of a patient, and 3D printing the upper and lower tooth molds of the patient;

4. manually operating the upper dental model and the lower dental model to move to a designed occlusion posture to generate a new jaw plate;

5. the dental bones of the patient are adjusted by utilizing the basic orthodontic size, so that the upper dental bones and the lower dental bones of the patient are completely occluded with the new jaw plate, the upper dental bones and the lower dental bones are fixed, and the malposition orthodontic operation is completed.

The existing dental model articulator generally adopts an upper dental model plate and a lower dental model plate, wherein the upper dental model plate can rotate around a fixed mechanical rotating shaft, and the action of simulating the occlusion of the dental models is achieved by rotating the upper dental model plate. Wherein the manufactured tooth mould is fixed and jacked to the upper tooth mould plate and the lower tooth mould plate through glue.

Because the distance from the teeth of each patient to the mandible is different, and the teeth occlusion process is not a simple axial rotation action, the manual operation has the problems of insufficient precision, poor repeatability and the like, and the treatment effect is seriously influenced, so that an operation jaw plate manufacturing device and method which can be quantized and conveniently operated are urgently needed.
