Description

Technical Field

[0001] The utility model relates to the technical field of dental orthodontic instruments, in particular to a ceramic orthodontic bracket with a metal mesh bottom. Background Art

[0002] Brackets are important components of fixed orthodontic technology. They are directly bonded to the surface of the crown with adhesives. The archwire is pulled through the bracket to apply various types of corrective forces to the teeth. Brackets are generally made of stainless steel, bioceramics or composite resins.

[0003] The existing technology often uses ceramic brackets or metal brackets for tooth correction. The operator first polishes the surface of the tooth, then applies adhesive to the tooth surface, and then adheres the brackets to the tooth surface in turn, and then uses a light curing lamp to quickly cure the adhesive to fix the brackets on the tooth surface. Compared with metal brackets, ceramic brackets have the advantages of being transparent, invisible, high in strength and not easy to deform.

[0004] However, since ceramic brackets are not easy to deform, they are likely to cause damage to tooth enamel when they are removed clinically. In addition, the surface of ceramic brackets is relatively smooth, resulting in low bonding strength of ceramic brackets, which can easily cause them to fall off, making it inconvenient to connect and remove ceramic brackets.
