Background
In orthodontic treatment, the correct position of the bracket on the teeth of a patient is a key technology. During traditional just abnormal treatment, the doctor relies on clinical experience, directly pastes the support groove on the tooth surface through the naked eye, has not only taken a large amount of chair time, pastes the difficult assurance of the precision in support groove moreover, causes unexpected tooth to remove easily, has prolonged and has rescued the time, influences and finally corrects the effect, causes unnecessary doctor-patient contradiction.
With the development of digital orthodontic technology, a personalized bracket indirect bonding positioner appears in the orthodontic field. The general work flow is as follows: firstly, scanning the relation of 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 of 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.
Clinically, the existing bracket indirect bonding positioner can be divided into a single body type, an integral type and a free type in structure, and different structures have respective advantages and disadvantages. The single type structure is that a single positioner respectively corresponds to each tooth, the positioner is easy to remove from the tooth after being bonded, but the groove on the single positioner is not stably bonded with the dental socket of a patient, so that the positioning accuracy of the bracket on the tooth can be reduced; the integral structure positioner is stably and tightly attached to the dental socket, and although the bracket combination on each tooth can be assembled in place at one time, the positioner is difficult to remove and is long in operation time; the free type structure can freely combine the positioners according to clinical needs to realize segmented bonding and removal, but the structure still lacks necessary combination guide, and position shielding can be caused by disordered bonding sequence to cause that part of the positioners are not bonded.
