OBJECTIVE: Correctly recognize the important role of brackets in the correct positioning and adhesion of straight braces, which directly affects the progress of treatment and the outcome of the treatment. It is one of the key steps in orthodontic treatment. Methods Materials: The accurate measurement of the clinical crown center point with the use of brackets locator, combined with clinical experience timely adjustment to facilitate orthodontic treatment. Clinical treatment, all patients with Hangzhou New Asia Dental Materials Co., Ltd. produced standard straight wire brackets orthodontic treatment. Brackets all non-mix-type composite resin enamel adhesive. Etching agents are etched using Gluma acid ethers produced by Heraeus Gusa Dental Products. CONCLUSIONS: The application of a preformed straight archwire to orthodontic archwire has become a highly effective appliance, with the brackets being attached to the patient’s teeth to become integral with the teeth, delivering strength and direction, with proper adherence to be reduced The reciprocation of the teeth, the more accurate adjustment of the teeth, simplifies the clinician’s chair next to the operation time to shorten the course of treatment.
