Description

Digital display bracket remover

technical field

The invention relates to the technical field of bracket removal, in particular to a digital display bracket removal instrument.

Background technique

With people's pursuit of beauty, more and more people wear brackets for orthodontics to make crooked teeth more straight. Brackets are an important part of fixed orthodontic technology. They are directly bonded to the surface of the crown with an adhesive, and the arch wires pass through the brackets to apply various types of orthodontic forces to the teeth. Common brackets are mainly made of stainless steel and bioceramics. Its main function is to fix the arch wire, so that the arch wire can play a better role and transmit the orthodontic force, so as to control the three-dimensional movement of the teeth and achieve the purpose of orthodontic treatment. When the orthodontic treatment is completed, the brackets that are attached to the teeth need to be removed. Usually, the doctor will use clamps to remove the brackets.

The existing Chinese patent with publication number CN105455908A discloses bracket removal pliers, including pliers handles hinged to each other, the front end of the pliers handle is extended with a clamping arm, and the upper surface of the clamping arm The lower surface of the arm is an upward slope, the front end of the clamping arm is provided with a clamp beak, the clamp beak and the clamp arm form a V-shaped connection structure, and the projection of the contour of the clamp beak on the vertical plane is built in the contour of the clamp handle. The pliers beak is a wedge-shaped structure of equal section with an arc-shaped cutting edge. The arc-shaped cutting edge of the pliers beak is arranged toward the inside and protrudes from the inner side of the clamping arm. When the pliers handles are completely closed, the arc-shaped cutting edge is maintain a preset gap distance between them.
