A manufacturing process of digital orthodontic guide plate

Abstract

The invention relates to the technical field of dental orthodontic bracket positioning production, in particular to a manufacturing technology of a digitized orthodontic guide plate. The manufacturing technology comprises the following steps of 1 model taking; 2 finishing; 3 scanning; 4 tooth arranging; 5 bracket position setting, wherein a bracket is arranged according to the tooth radian obtained after tooth arranging and a tooth body cross positioning method; 6 guide plate frame designing, wherein a guide plate frame is designed according to the shape of an occlusal surface of a tooth model, the width of the guide plate frame is 10 mm, the height is 5 mm, and the length is consistent with the dental arch radian; 7 3D printing of the model, wherein the designed model is output and printed into a resin model; 8 guide plate manufacturing, wherein the printed model is installed into the bracket according to the tooth positions and fixed through light wax; 9 light curing, wherein the surface of the guide plate is pressed to be smooth through light wax, and then the guide plate is put into a light curing machine to be subjected to hardening treatment; 10 brightener applying. The manufacturing technology is simple, the bracket position is very accurate, operation and control are convenient, and the time that a doctor performs adhesion in an oral cavity is shortened by 70%.

Description

technical field [0001] The invention relates to the technical field of tooth orthodontic bracket positioning production, in particular to a manufacturing process of a digital orthodontic guide plate. Background technique [0002] Dental orthodontic treatment has undergone many changes so far, from the initial multi-bracket fixed appliance technology to the current lingual bracket wire treatment. Multi-bracket fixed appliance: it is the product of correcting irregular teeth for those with deformed teeth in the early stage. The initial brackets are used to bond the sides of the teeth, which are connected in series by steel wires to achieve the leveling of the teeth. Curative effect, but because the bracket and the steel wire are all metal products, not only makes the patient's face unattractive, but also easily scratches the patient's face and pinches the tissue, causing pain and other undesirable phenomena.

Problems solved by technology

Multi-bracket fixed appliance: It is the product of correcting irregular teeth for those with deformed teeth in the early stage. The initial brackets are used to bond the sides of the teeth, which are connected in series by steel wires to achieve the leveling of the teeth. However, because the brackets and steel wires are made of metal, it not only makes the patient's appearance unattractive, but also easily scratches the patient's face and pinches tissue, causing pain and other adverse phenomena.

The lingual bracket appliance: it puts the bracket on the lingual side of the teeth, which can not only play the role of orthodontics, but also not affect the aesthetics of the patient's face, but all its metal colors are hidden in the The inside of the teeth prevents the patient from seeing the metal color on the outside, but it is quite inconvenient for the doctor to stick the brackets in the mouth, and the space on the lingual side of the teeth is very small, which is even more difficult to operate, resulting in the existing brackets. The groove is easy to fall during the bonding operation, and the existing bracket bonding can only be used for bonding a single tooth, and because of the small space inside the oral cavity, it is inconvenient for the doctor to bond. Usually, it takes 90 minutes to bond a tooth, causing the patient open mouth for a long time
