Wx series bracket and buccal tube

Abstract

The invention discloses dentistry appliance used for orthodontic treatment of first molar and second molar, specifically a wx series bracket and buccal tube. The wx series bracket comprises bracket bottom plate; a slot, bracket wings and a position slot are arranged on the bracket bottom plate in sequence; according to different tooth position and molar morphology, the bracket has three offset angles with different angles, namely theta1, theta2 and theta3, wherein, theta1 is 4 to 10 degree, theta2 is -5 to -3 degree and theta3 is 0 degree; wx series buccal tubes comprises a buccal tube bottom plate, a tube body of the buccal tube and a slot of the buccal tube are arranged on the buccal tube bottom plate, a towing hook is arranged on the tube body of the buccal tube. According to different tooth position and molar morphology, the buccal tube has three offset angles with different angles, namely theta'1, theta'2 and theta'3, wherein, theta'1 is 4 to 10 degree, theta'2 is -5 to -3 degree and theta'3 is 0 degree. The wx series bracket and buccal tube is suitable for more different types of orthodontic patient, molar rotation is effectively reduced or avoided and a better occluding relation is built.

Description

technical field [0001] The invention relates to orthodontic materials in medical materials science, which is a dental appliance used for orthodontic treatment of first molars and second molars, specifically wx series brackets and buccal tubes. Background technique [0002] In modern orthodontics, most of the MBT and ROTH data brackets and buccal tubes are used, which can be applied to most clinical patients. They have the advantages of easy operation and short treatment time, but MBT data and ROTH data are based on Western The normal occlusal data of human beings are designed and improved, and there are differences for oriental races. In clinical work, it is found that some patients with malocclusion who use fixed appliances have molar rotation during orthodontic treatment, which is not conducive to the establishment of a good occlusal relationship between the upper and lower teeth. In 2006, Zeng Xianglong, a scholar of Peking University, researched and developed the straig...
