Individually tailored lingual orthodontic bracket and method for manufacturing same bracket

Abstract

The present invention relates to an individually tailored lingual orthodontic bracket and a method for manufacturing the bracket and, more particularly, to an individually tailored lingual orthodontic bracket and a method for manufacturing the bracket, wherein a bracket base, which is used for lingual orthodontics, is cast to manufacture a bracket, which is tailored to individual teeth of a patient, such that the bracket can be attached in an accurate position during an orthodontic procedure, without falling off from the teeth, thereby improving the orthodontic efficiency. Provided are a manufacturing method and a bracket fabricated by the manufacturing method, the method comprising: cutting individual teeth from a malocclusion model, which has been modeled on the patient, and rearranging them in an ideal position; fabricating a set-up model and replicating the set-up model; performing pin work on the replicated set-up model and expanding the base of the bracket using a resin to prepare casting; injecting an investment into a casting ring, which has been prepared for casting, to be invested; and burning out the resin and casting the melted material.

Description

technical field [0001] The present invention relates to a custom-made bracket for lingual orthodontics and a manufacturing method for the bracket. More specifically, it relates to a casting (Casting) bracket base plate used for lingual dentition correction, thereby manufacturing a bracket suitable for The brackets for each tooth of the patient enable the brackets to be attached to the correct position during orthodontics and prevent them from detaching from the teeth, thereby improving the efficiency of orthodontics. Personalized brackets and brackets for lingual orthodontics The manufacturing method of the bracket. Background technique [0002] Many people have irregular dentition due to abnormal development of teeth or chin bone or bad habits in childhood. When the dentition is irregular, it will experience many difficulties in daily life. [0003] In order to solve this problem, dentistry is using brackets 10 for orthodontics, such as figure 2 As shown, the bracket 10 i...

Problems solved by technology

[0009] However, if the resin base is made by filling resin between the bracket base and the tooth surface, the distance between the impedance center of the tooth and the groove of the bracket to which the force is applied becomes correspondingly farther because the resin base is too thick. , resulting in the easy separation of the bracket base plate and the resin base plate, and the problem of difficult control of the teeth

[0010] In addition, if the treatment period is longer, the saliva in the mouth will be absorbed by the resin base plate formed on the bracket base plate and form an unpleasant smell.

[0011] Moreover, due to the small size of the bracket base plate, if the resin base plate is not enlarged, there may be errors, so that it cannot be accurately attached to the tooth surface of the patient. If the resin base plate is increased in order to solve the problem , then the absorption of saliva will increase, and further unpleasant odors will occur.

[0012] The brackets are made of a resin base that is suitable for each person's teeth, so if the resin base falls off during orthodontic treatment, it cannot be easily rebonded to the lingual side of the tooth in the dentistry, and it needs to be sent to a dental laboratory After remake etc., causing various problems

[0013] In addition, the process of cutting off the dental metal film and attaching it to the tooth surface in order to make the metal base plate in the said authorized patent is complicated, and it is difficult for the metal film to accurately adhere to the tooth surface. In addition, the metal base plate and the bracket base plate are welded with silver solder or the inconvenience of performing laser welding

In addition, there is a concern that the bracket base plate or the metal base plate will be detached from the brazed and welded parts
