Vacuum forming improved Activator appliance and production method thereof

Abstract

The invention discloses a vacuum forming improved Activator appliance, which comprises an upper jaw dental arch diaphragm plate and a lower jaw dental arch diaphragm plate which are adhered into a whole through transparent adhesive, wherein the upper and the lower jaw dental arch diaphragm plates are closely adhered with each other and are parallel and level to dental necks, and lower jaw back oeclusals at the two sides are planar guide plates; the dental arch diaphragm plate of a lower jaw dental lingual side is provided with a flange which extends to a part 5mm-10mm below a dental neck edge, and the flange is arranged aside and undercut; lower jaw lingual back dental arch parts at the two sides of the dental arch diaphragm plate of the lower jaw dental lingual side are windowed, and a front dental lingual arch diaphragm plate is reserved; and the upper jaw dental arch diaphragm plate and the oeclusal part of the dental arch diaphragm plate of the lower jaw dental lingual side are adhered into a whole through the transparent adhesive. The vacuum forming improved Activator appliance has a reasonable structure, is easy for patients to cooperate, and is not toxic, is tasteless, is comfortable to wear and has the invisible effect because the appliance is made by transparent materials, and the benzene and dust pollution during the manufacturing process is solved. Clinical tests prove that the clinic therapeutic effect can be improved and the therapeutic time is shortened.

Description

technical field [0001] The invention relates to a vacuum-formed modified Activator appliance and its manufacture. The prepared vacuum-formed modified Activator appliance is mainly used for treating Angle II dentition, functional and mild osteoarthritis in mixed dentition and early permanent dentition. Sexually wrong Correction of deformities. Background technique [0002] Angle class II error common clinical error One, my country's Type II fault It occupies the second place in malocclusion. Fu Minkui reported in 2000 that the prevalence of Class II malocclusion in China was 25.77%, and the initial stage of permanent teeth accounted for about 19.41%. About 49% of the patients had mandibular retraction, 62% had normal maxillary position, and 38% had abnormal position. It has a great impact on the physical and mental health of patients, and the rate of clinical visits is high. At the end of the 18th century, Kingsley, the "father of orthodontics" in the United States,...

AI Technical Summary

Problems solved by technology

However, the traditional Activator appliance is made of hand-bent steel wires and coated with self-curing plastic. The benzene pollution is heavy, the polishing is time-consuming, there is a lot of dust, and the thickness of the substrate is difficult to control. It is difficult for ordinary technicians to do it. Skilled technicians need 4 hours to complete it.

When first wearing the appliance, it is difficult for the patient to cooperate because of the thick and smelly appliance. It takes a long time to adapt to the swallowing function and cannot speak. It is difficult to promote and apply it in clinical practice. Simpler humanized and high-quality Activator appliance with good biological performance, and many improvements and attempts have been made, but none of them can be separated from self-gel and steel wire, so that patients with allergies cannot wear the appliance. In order to expand the indications and Promotion and application, the orthodontic community has made unremitting efforts

[0003] Vacuum embossing technology has a history of more than 20 years. It has been introduced in my country for nearly ten years, but it is limited to the production of simple aligners such as lamination retainers. There are no detailed literature reports on the development of Activator aligners using vacuum embossing technology.
