Description

Technical Field

[0001] The present invention belongs to the technical field of dental correction devices, and in particular relates to a miniature dental correction device with a memory function and a method thereof. Background Art

[0002] Malocclusion not only affects the teeth themselves, but also the facial bone structure, which ultimately affects the patient's facial appearance. Deformities of teeth make it impossible to chew food normally, resulting in indigestion. Deformities of teeth make it impossible to clean up food residues during brushing, resulting in oral diseases. The most commonly used braces now are wire braces, which are made of high-quality stainless steel wires. The cross-section is diamond-shaped and mechanically rolled into spring-shaped threads. The diameter of the wire braces is larger than the screw hole. When installing, the wire braces are compressed and tightened. After installation, they bounce back to their original shape, making the wire braces permanently fixed in the screw hole. This correction method is simple and effective, but it has disadvantages such as poor aesthetics and low comfort. Bracketless invisible braces appeared in the 1940s. They are a new type of braces for correcting malocclusion. They use a series of removable appliances made of transparent materials to move the teeth in a small range to correct malocclusion. They have the advantages of being beautiful, convenient and having predictable therapeutic effects. However, they have disadvantages such as a complicated treatment process (braces need to be replaced every two weeks) and a long cycle. Summary of the invention

[0003] The purpose of the present invention is to provide a miniature dental brace with a memory function and a method thereof, so as to solve the problems of poor aesthetics and low comfort of existing wire braces and complex and long treatment period of invisible braces without brackets.
