Abstract

The invention discloses a bracket matching method based on orthodontics. The bracket matching method based on orthodontics comprises the steps that initial structure information of upper teeth and lower teeth of a patient is obtained; orthodontics structure information of the upper teeth and the lower teeth is obtained according to the initial structure information; orthodontics device distribution information of the upper teeth and the lower teeth is obtained according to the orthodontics structure information; tooth models and orthodontics devices are made according to the orthodontics structure information and the orthodontics device distribution information; when a corresponding tooth bracket of the teeth of the patient drops in the orthodontics process, a bracket identical with the dropping bracket is obtained by carrying out matching according to the made orthodontics devices, and re-fixing is carried out. According to the bracket matching method based on orthodontics, the ideal positions of the teeth are foreknown before treatment is started, the positioning brackets and the ideal arch wire form are designed with assistance of a computer, tooth face positioning bodies are obtained through 3D printing to be combined and assembled with the practical bracket and a bracket linkage frame, the chair side operation time of a doctor is greatly shortened, the treatment time is shortened, and the orthodontics efficiency is improved.

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like figure 1 Shown is a bracket matching method based on orthodontics provided by an embodiment of the present invention, including:

[0028] S11. Acquire initial structure information of the upper teeth and lower teeth of the patient's teeth, where the initial structure information is the tooth arrangement information of the patient's teeth in an uncorrected state.

[0029] In this step, it should be noted that three-dimensional scanning technology is used to scan the patient's oral teeth or plaster models in an uncorrected state, and three-dimensional data information of the upper teeth and lower teeth is obtained; A three-dimensional image of a tooth structure, and the three-dimensional image of the initial tooth structure is the initial structure information.

[0030] S12. Obtain the orthodontic structure information of the upper teeth and the lower teeth of the patient's teeth according to the initial structure information, where the orthodontic structure information is the tooth arrangement information of the patient's teeth in a orthodontic state.

[0031] In this step, it should be noted that each tooth image in the initial three-dimensional image of the tooth structure is subjected to movement processing to obtain a three-dimensional image of the tooth structure in a rectified state.

[0032] S13. Obtain the orthodontic device arrangement information of the upper teeth and the lower teeth of the patient's teeth according to the orthodontic structure information, where the orthodontic device arrangement information includes the brackets arranged on each tooth in the patient's orthodontic state, Arrangement information of tooth surface positioning body, adapter frame and arch wire.

[0033] In this step, it should be noted that the positioning of the orthodontic device is performed on each tooth on the three-dimensional image of the tooth structure in the rectified state, and the three-dimensional image of the orthodontic device is obtained according to the pre-formed bracket.

[0034] S14 , making a tooth model and an orthodontic device according to the orthodontic structure information and the orthodontic device arrangement information.

[0035] In this step, it should be noted that the correction device is obtained according to the three-dimensional image of the tooth structure in the correction state and the three-dimensional image of the correction device. Then, according to the three-dimensional image of the orthodontic device, obtain the three-dimensional image of the bracket, tooth surface positioning body, and connecting frame corresponding to each tooth; according to the three-dimensional image of the bracket, tooth surface positioning body, and connecting frame corresponding to each tooth The tooth surface positioning body is obtained by printing technology.

[0036] S15. When the patient's teeth fall out of the corresponding brackets during the orthodontic process, match the produced orthodontic devices to obtain the same brackets as the dropped brackets, and re-fix them.

[0037] According to the tooth surface positioning body obtained by printing, combined with the actual bracket and adapter frame, the initial information is positioned and transferred, so that the determined archwire shape and bracket position in the computer are output.

[0038] The virtual brackets and the positioning transfer adapter are obtained by 3D scanning of the preformed brackets and the bracket positioning transfer adapter, and the brackets are positioned on the tooth row model by combining the ideal archwire shape and the virtual bracket positioning transfer rack. Then, the tooth surface positioning body is made according to the anatomical shape of each tooth. The 3D printed tooth surface positioning body is used to assemble the pre-formed brackets and bracket positioning and transfer adapters to the solid plaster model. Arrange the misaligned teeth to an ideal state according to the shape of the dental arch, and then compensate the data required for each tooth to the prefabricated position with resin brackets to the prefabricated bracket backing plate.

[0039] The bracket matching method based on orthodontic treatment provided by the present invention predicts the ideal position of the teeth before starting the treatment, adopts computer-aided design to locate the bracket and the ideal arch wire shape, and prints the tooth surface positioning body and the actual bracket through 3D printing. The combination of the slot and the bracket joint frame greatly shortens the doctor's chairside operation time, shortens the treatment time, and improves the treatment efficiency.

[0040] The above are only preferred embodiments of the present invention, but the protection scope of the present invention is not limited to this. Any person skilled in the art who is familiar with the technical scope disclosed by the present invention can easily think of changes or replacements. should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
