Description

Technical Field

[0002] Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts. Brackets are important components of fixed orthodontic technology. They are directly bonded to the surface of the crown with adhesives, and the archwires apply various types of corrective forces to the teeth through the brackets. Brackets are made of stainless steel, bioceramics or composite resins. Their main function is to fix the archwire so that the archwire can play a better role and transmit the corrective force, thereby controlling the three-dimensional movement of the teeth and achieving the purpose of orthodontic correction. The bracket is composed of a bracket body and a bracket base plate. According to whether the bracket body and the bracket base plate are integrally formed, they are divided into one-piece brackets and split brackets.
