In orthodontic treatment, the bonding strength of the bracket on the tooth surface of a patient is a more critical technology. During conventional orthodontic treatment, each bracket is bonded directly to the tooth surface of the corresponding tooth of the patient by the physician. Such an operation may result in inaccurate and unstable bonding of the bracket to the tooth surface. Therefore, with the development of digital orthodontic technology, the bracket indirect bonding positioner appears in the orthodontic field. The general work flow is as follows: firstly, scanning the relation of the malocclusion teeth of a patient by using a scanner to obtain a digital model, then marking the bonding position of a bracket on the digital model by using orthodontic software, designing an orthodontic positioner structure capable of bonding the bracket to a specified position, and finally processing a personalized orthodontic positioner by using a 3D printer for indirect bonding by a clinician. The personalized bracket indirect bonding positioner utilizes digital tooth arrangement and 3D printing technology, realizes accurate positioning of the bracket, greatly shortens the time beside a chair for directly bonding the bracket manually, and brings convenient operation for doctors.
In the traditional orthodontic treatment, a doctor needs to determine a good bonding position by clinical experience, the bonding position is the key of the orthodontic treatment, but the bonding strength is also a factor which must be considered. In order to provide a snug fit of the bracket web base to the patient's tooth surface, the physician typically habitually presses the bracket during bonding to provide a more snug fit to the patient's tooth surface. Due to the operation, most of the adhesive can overflow, so that the adhesive between the bracket net bottom and the tooth surface of the patient is reduced, the adhesive strength is further reduced, meanwhile, a large amount of adhesive remains on the tooth surface of the patient due to the existence of a large amount of overflow glue, and the excessive glue cleaning also occupies a large amount of time beside the chair of a doctor.
Similarly, when the cooperation just abnormal locator uses, some bracket position and patient flank of tooth distance can be too big, and the doctor presses just abnormal locator in addition, also can lead to the uncertainty in bracket net bottom and patient flank of tooth clearance like this, and the binder can be too much when the distance is too big to lead to the adhesion to descend, still can make the excessive glue remain on patient flank of tooth. Thus, the correction effect is finally influenced, and unnecessary doctor-patient contradiction is caused.

Because of the support pillar 300, the clamp end 100 can keep a preset distance from the tooth surface, when the bracket is placed in the concave structure of the clamp end 100, even if a doctor squeezes the orthodontic positioner, the bottom surface of the net of the bracket can keep a distance from the tooth surface, so that the problems that the adhesive overflows due to the fact that the bracket is squeezed towards the tooth surface, the adhesive force is reduced, and a large amount of adhesive overflows are avoided.
Further, the supporting column 300 and the fixture end 100 are matched with each other, and the supporting column 300 of the orthodontic positioner corresponding to each tooth can keep a preset distance between the corresponding bracket and the tooth surface when the tooth surface is abutted by the supporting column 300 of the orthodontic positioner corresponding to each tooth through scanning the tooth digital model and adjusting parameters before the orthodontic positioner is manufactured. Therefore, the distance between the bracket corresponding to each tooth and the tooth surface can be kept, the bonding force of the bonding agent of the bracket and the tooth surface is prevented from being reduced, the condition of glue overflowing at four positions is avoided, and the bonding stability of the bracket and the cleanness of the tooth surface are further ensured.
