Description
Technical Field
The utility model relates to the field of orthodontic treatment, in particular to a double-jaw plate device and a concealed correction system comprising the double-jaw plate device.
Background
Class II orthognatics are one of the clinically common types of orthognatics, which are mainly clinically manifested by anterior maxillary molar movement and abnormal mandibular misorientation, and currently there are a variety of functional appliances that can guide mandibular forward growth, such as Herbst appliance, forsus appliance, frankel function regulator, twinblock appliance, etc. The functional correction method is a very effective means for early intervention and early treatment of teenagers, the double-jaw correction technology is one of the common functional correction methods, and the proper biting force is transmitted to the dentition and the jawbone through covering the biting inclined plane of the posterior teeth, so that the functional correction force is applied to the developing dentition to the greatest extent, and the correction effect is widely accepted.
Because the orthognathic plate correction cannot give consideration to the aesthetic property, and the transparent appliance has the invisible and attractive effect, the transparent appliance based on the orthognathic plate correction appears in the orthodontic field. In order to achieve repositioning of the mandible, the existing transparent appliance with a double jaw plate adopts two structures: one is to design a jaw pad-shaped bulge on the maxillary surface of the transparent appliance, and design a bulge on the mandibular premolars area to form upper and lower corresponding occlusal surfaces, wherein the mandible of a patient is in a forced forward extending position when the patient is occluded; the other structure is that the cheek side of the molar is designed to be convex to form a resistance surface corresponding to the upper and lower parts, so that the lower jaw is extended forwards.
Although the transparent appliance is more invisible, beautiful, comfortable and safe compared with the metal appliance, the transparent appliance still has the defects in the prior art when the transparent appliance is applied to the double jaw plate: under normal occlusion conditions, the upper and lower jaws are not easily laterally displaced, however, after the addition of the jaw pad, due to the separation of the upper and lower jaw teeth, lateral constraint is released, and although the prior art can accurately position the lower jaw in the disfigurement direction, an effective positioning mechanism is lacking in the lateral direction, so that a good upper and lower jaw position relationship cannot be established. In addition, the ideal contact between the upper and lower jaw surfaces of the transparent appliance is planar, but the upper and lower jaw contact surfaces of the appliance actually processed are mostly point contact due to design and manufacturing errors and the like, so that lateral restraint of the upper and lower jaws actually appears worse, and even in an ideal occlusion state, lateral movement of the lower jaw occurs for a patient, which is unfavorable for establishing a good upper and lower jaw positional relationship.
In addition, the existing transparent appliance with the double jaws is of an integrated structure, the jaws and the transparent shell are integrally molded by injection molding and film pressing, and the jaws cannot be separated from the transparent appliance; however, the correction process has a plurality of different stages, and the jaw plate can be applied in one stage or a plurality of stages, which means that the patient needs to be provided with a plurality of transparent correction devices in the whole correction period, and the correction cost is high.
