Embodiment 1

[0059] This embodiment provides a treatment system for concave jaw deformity. The concave jaw deformity is mainly caused by inertial drafting of the mandible. The upper jaw is mildly to moderately underdeveloped, and the lower jaw preferably has a flat rectangular shape. The clinical orthodontic feature of concave jaw deformity is that the mandible can be forced back to the incisor of the upper and lower anterior teeth, and the posterior teeth are open because of the deep spee curve of the mandible. see figure 1 , which is an example image of the initial jaw. The core of this embodiment is to force the protruding mandible back to the upper and lower anterior incisors, on this basis, apply the maxillary reverse traction, and finally achieve the goal of mandibular remodeling and occlusal reconstruction, and realize the synchronous orthopedic treatment. Further realize the efficient invisible treatment of concave deformity.

[0060] see Figure 2-Figure 4 , The correction syst...

Embodiment 2

[0073] This embodiment provides a correction system for concave jaw deformity, similar to Embodiment 1, the difference is that the correction system for concave jaw deformity provided by this embodiment also includes a mandibular shell-shaped dental instrument 2, a mandibular shell-shaped The dental instrument 2 includes a cavity shell-shaped body for accommodating a number of mandibular teeth. At the same time of jaw orthopedic reshaping, the shape of the anterior tooth area of ​​the mandibular shell-shaped dental instrument gradually changes so that the corresponding teeth are gradually depressed from the initial position to the orthodontic target position . In this embodiment, the upper and lower jaws wear the shell-shaped dental instrument at the same time to realize the simultaneous correction of the upper and lower jaws. Specifically, when the upper jaw undergoes simultaneous jaw correction and tooth correction, the lower jaw shell-shaped dental instrument also performs t...

Embodiment 3

[0079] see Figure 6 , this embodiment provides a principle diagram of Embodiment 3 of a correction system for concave jaw deformity. Similar to Embodiment 2, the difference is that the orthodontic system for concave jaw deformity also includes the first intermaxillary traction member 31 set on the maxillary shell-shaped dental instrument and the second intermaxillary traction set on the mandibular shell-shaped dental instrument Part 32, after jaw orthopedic remodeling, the first intermaxillary traction part 31 and the second intermaxillary traction part are connected by elastic part 33, so that the upper and lower jaw teeth can adjust the occlusal relationship. Specifically, after the bone orthopedic remodeling in Example 1, with the fine adjustment of the occlusion as the main goal, the intermaxillary traction device can be used to perform Class III intermaxillary traction, and the attachments of the upper and lower dentition can be replaced according to the orthodontic need...

Abstract

The invention relates to a dental-facial deformity orthopedics system and a design method thereof. The dental-facial deformity orthopedics system comprises an upper jaw shell dentistry apparatus having a shell-shaped body, wherein a protrusion part is arranged at a position of a molar tooth region corresponding to the shell-shaped body in the direction opposite to the jaw in a protruding manner; atraction part is arranged on the labial side surface of the shell-shaped body; a position fixing part which is in snap fitting with a position fixing accessory is arranged at the molar tooth region corresponding to the shell-shaped body; the protrusion part cooperates with the molar tooth region in the lower jaw for performing meshing reconstruction, so that the incisor teeth on the lower jaw andthe incisor teeth on the upper jaw tend to be aligned; the traction part cooperates with the upper jaw to perform extra-jaw reverse traction, so that the jaw bones are subjected to shape straightening and re-molding; and the position fixing part is clamped with the position fixing accessory to prevent the upper jaw shell dentistry apparatus from falling from the teeth which cooperates with the upper jaw shell dentistry apparatus. The design method is a design method of the dental-facial deformity orthopedics system. The dental-facial deformity orthopedics system having treatment pertinence can be designed, so that the treatment of dental-facial deformity is realized.

Description

technical field [0001] The present invention relates to the technical field of medical devices, more precisely, relates to tooth correction design technology, in particular to a correction system for concave jaw deformity and a design method for the correction system for concave jaw deformity. Background technique [0002] Malocclusion refers to the congenital genetic factors or acquired environmental factors during the growth and development of children, such as diseases, bad oral habits, tooth replacement disorders, etc., and can also be caused by trauma, periodontal disease and other reasons after growth and development. Such as irregular arrangement of teeth, abnormal occlusal relationship between the upper and lower dental arches, abnormal size, shape and position of the jaw, facial deformities, etc. The formation factors and mechanisms of malocclusion are complex, and the occurrence process may be caused by a single factor and a single mechanism, or it may be the resul...
