Background
The accuracy of the bracket bonding position directly influences the correction effect, and the accuracy of the bracket bonding position is the basis of good correction treatment in clinic. However, in the clinical working process, two methods are commonly used for bracket positioning:
direct bonding: the doctor with rich experience confirms the position of bracket on the tooth face under the experience of self years accumulation, because position or visual fatigue often take place the inaccurate condition of bracket location, influence the range of tooth, and direct bonding under the vision wastes time and energy, has greatly prolonged the other operating time of chair, and young doctor can cause the placing position of bracket to have great deviation owing to bracket locating ruler such as cross bracket locating ruler or bracket locating lever place slight skew when fixing a position with the help of bracket locator. The bracket locating rod needs to be perpendicular to the labial surface of the teeth to accurately locate, an operator needs to determine the position where the bracket locating rod is placed in the right rear direction and the side direction, and the position of the bracket is repositioned after the bracket locating rod is placed accurately, so that the operator is easy to feel tired in vision and cervical vertebra tired. The design of the existing bracket positioner is either complex in structure or too simple in structure and too single in function, and is limited in clinical application.
Indirect bonding: this technique performs accurate analysis of the model in a laboratory, repositioning and bonding the brackets, transferring the brackets to individual trays by a film-pressing technique, and finally bonding the brackets to the teeth by a doctor. The technology can achieve accurate positioning and bonding of the bracket, saves the operation time beside a chair of a clinician, and has the defects of higher cost, high manufacturing period, overlong manufacturing period, more complex technology and the like.

As a further improvement of the invention, the shape and the size of the bracket positioning opening are consistent with the bottom of the orthodontic bracket.
As a further improvement of the invention, the position of the bracket positioning opening corresponds to the position of the orthodontic bracket to be placed on the tooth surface.
As a further improvement of the invention, the locator body covers at least more than 50% of the buccal side area of the tooth.
As a further improvement of the invention, the bracket positioning opening is a through hole which is hollowed out or a notch with an open bottom edge.
In order to achieve the above purpose, the invention provides a manufacturing method of a personalized bracket positioner, comprising the following steps:
step one: taking out the plaster tooth model in the mouth of the patient and generating a 3D digital model in a computer by using a 3D scanner;
step two: manufacturing a dental film pressing holder on the tooth model by using a vacuum film pressing machine;
step three: analyzing the tooth 3D digital model in a computer through orthodontic software to automatically generate the accurate position of an orthodontic bracket on the tooth surface;
step four: after the position of the orthodontic bracket is determined in a computer, connecting cutting equipment, and cutting the dental film pressing retainer on the model in the second step to manufacture a personalized bracket positioner;
step five: and placing the personalized bracket positioner into the mouth of a patient, and placing and bonding orthodontic brackets according to the corresponding positions of the positioner on the tooth surfaces.
As a further improvement of the present invention, in the step four, in order to cover the dental film pressing holder on the model of the step two, after the position is determined in the computer, the computer sends the position data to the automatic cutting device, and the cutting is automatically completed by the cutting device.
The invention has the beneficial effects that: 1. compared with the direct bonding method, the method can accurately position the position of the bracket on the tooth surface, and greatly reduces the time beside the chair; 2. compared with indirect bonding, the method greatly reduces the processing cost and the processing period.

Detailed Description
The invention will be further described with reference to the drawings and the specific examples.
As shown in fig. 2, the present invention provides a personalized bracket locator comprising: a positioner body 1 and a bracket positioning port 2. The positioner body 1 is a dental impression holder manufactured from a plaster dental model, which is generally made of resin and is press-molded using a thermoforming machine or a film press. The shape of the positioner body 1 is matched with the shape of all exposed teeth of the upper row or the lower row, and the positioner body 1 covers all exposed teeth of the upper row or the lower row. The retainer body 1 is provided with a bracket locating opening 2 at the side face of the cheek side of each tooth where the orthodontic bracket needs to be installed, the position of the bracket locating opening 2 is consistent with the position where the orthodontic bracket is to be placed on the tooth face, and the shape and the size of the bracket locating opening 2 are consistent with the bottom of the orthodontic bracket. Since the orthodontic bracket is generally fixed to the middle of the buccal side of the tooth, the retainer body 1 covers at least 50% or more of the buccal side area of the tooth to provide sufficient space for the placement of the placement port 2.
