Abstract

An orthodontic tray is characterized in that the orthodontic tray comprises an outer guiding plate arranged on a dentition, and a covering piece matched with the outer guiding plate and covering a bracket, the covering piece is a soft body formed by curing a fluid material on the bracket, the outer guiding plate includes a lip-cheek cavity, and the lip-cheek cavity covers the upper part of the covering piece. The orthodontic tray is a tool commonly used in indirect bonding. The orthodontic tray has a simple manufacturing process, can accurately position the bracket, can stably accommodate thebracket to prevent the bracket from falling, and also ahs the advantages of simplicity in operation, great shortening of the working time of orthodontists, and improvement of the working efficiency.

Description

technical field [0001] The invention relates to the field of orthodontic correction, in particular to the field of indirect bonding. Background technique [0002] In the process of orthodontic treatment, the bonding position of the bracket has a great influence on the treatment effect. Inaccurate positioning will lead to poor treatment effect of the patient and prolong the treatment period. At present, the positioning of brackets mainly depends on the clinical experience of doctors. Through visual observation, the error is relatively large; in addition, in clinical practice, doctors need to bond the brackets to the patient's tooth surface one by one, so the operation time is long and the patient's Comfort is low. In order to save the doctor's treatment time, improve the efficiency of clinical bonding, and obtain high-precision bracket positioning, the indirect bonding technology of brackets has emerged. The traditional bracket indirect bonding technology is to first bond t...
