All-ceramic self-locking bracket and opening method and locking method thereof

Abstract

The invention relates to an all-ceramic self-locking bracket and an opening method and locking method thereof and belongs to an orthodontic component. The traditional orthodontic brackets are mostly metal brackets. The metal brackets do not have the invisible effect in use, are not beautiful enough and have insufficient biocompatibility. The color of the ceramic bracket is close to that of the teeth so that it is not easy to notice when used, and the ceramic bracket has good biocompatibility. The ceramic material has low strength, large brittleness and fracture easiness relative to the metal bracket. The all-ceramic self-locking bracket comprises a bracket body, a sliding block and a positioning pin. The positioning pin is disposed on the bracket body. The positioning pin is located in thesliding groove of the sliding block. The sliding block slides so that the bracket is opened and locked. The all-ceramic self-locking bracket is prepared from a tough ceramic material, has a color ofmilky white similar to the human teeth color, and has an invisible function. The locking and opening switching of the bracket body is convenient and smooth. The slip sheet is not easy to break.

Description

technical field [0001] The invention relates to an all-ceramic self-locking bracket, an opening method and a locking method thereof, belonging to orthodontic components. Background technique [0002] Traditional orthodontic brackets are mostly metal brackets, which have no invisible effect when used, are not beautiful enough, and have insufficient biocompatibility. The color of ceramic brackets is close to that of teeth, it is more beautiful when used, and has good biocompatibility; however, compared with metal brackets, ceramic materials have disadvantages such as lower strength, greater brittleness, and easy fracture. The Chinese patent application number is 201710410495.9, which discloses an orthodontic self-ligating bracket, including a bracket bottom plate, and a bracket body arranged on the bracket bottom plate. The locking piece, the lower surface of the locking piece is provided with a first locking position and a second locking position, the first locking position ...

AI Technical Summary

Problems solved by technology

The above-mentioned self-locking bracket slides the locking piece to make the protrusion on the elastic part enter different locking positions to realize the opening or locking of the bracket body. When sliding the locking piece, the protrusion on the elastic part needs to pass through the transition position to reach another In the locking position, when the elastic part is received by the transition position, the elastic part contracts and stores energy. At this time, the locking piece is subjected to a large longitudinal force. If the self-locking bracket is made of ceramic material, due to the brittleness of the ceramic material, it will be damaged during use. It will cause cracking of the cleats; at the same time, the adhesive mesh includes multiple staggered protrusions, and the structural design of the adhesive mesh makes it thicker, making the overall height of the bracket higher and poorer in wearing comfort
