Cheek screen type invisible magnetic function appliance

Abstract

The invention belongs to the technical field of medical apparatuses and instruments, and particularly relates to a cheek screen type invisible magnetic function appliance. The appliance is characterized by comprising a base plate, a convex groove and a stress application magnetic block. The base plate covers the surface of the whole dentition in a total dentition wrapping mode and is tightly combined with the surface of the dentition; the convex groove is formed in the outer side face of the base plate and connected with the base plate into a whole; the stress application magnetic block is arranged inside the convex groove and fixed to the convex groove in a mechanical friction embedding; when upper teeth and lower teeth are closed, the upper jaw convex groove and the lower jaw convex groove are staggered, and during occlusion, the side face is tightly attached. The appliance is attractive, good in comfort, sufficient in orthopedic force, accurate in treatment effect, attractive, easily acceptable by a patient, easy and convenient to wear, easy to manufacture, small in occupied oral cavity body, capable of continuously performing strength landing and small in voice function influence.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a buccal screen invisible magnetic functional appliance. Background technique [0002] In addition to irregular teeth, there is also a type of jaw deformity that has a greater impact on facial development and the function of the stomatognathic system, such as the "underground" (skeletal class III deformity) caused by the overgrowth of the mandible. In the adolescent stage, timely functional orthopedic treatment can effectively correct such deformities. However, the correction of skeletal Class III deformity requires sufficient orthopedic force for sufficient time. [0003] Routinely used orthopedic devices include mask-type anterior traction, chin pocket, Frankle III, combined traction, magnetic double-resistance plate appliance, etc. These devices are large in size (such as Frankle III), have exposed steel wires (such as combined traction), and have Some...

AI Technical Summary

Problems solved by technology

Therefore, the existing orthopedic devices have the disadvantages of poor aesthetics, low comfort, great influence on speech function, poor controllability of force source, and complicated manufacturing process.

[0005] In addition, since the patients receiving orthopedic treatment are teenagers who are in the period of rapid physical and mental development, their self-awareness has gradually improved, and their attention to the appearance is increasing. Although the mechanical design of this type of orthopedic device conforms to the principle of orthodontic treatment, the clinical effect is relatively positive. , but a large part of patients with treatment failures are related to the inability to persist in using
