Orthodontic bracket system and tooth orthodontic method

Abstract

The invention discloses a traction / locking element, a traction / locking set, an orthodontic bracket, an orthodontic bracket system and a tooth orthodontic method. The traction / locking element comprises a strip-shaped nail body, wherein the area of the cross section of the nail body is 0.06-2.5 square millimeters, and the length of the nail body is 0.8-4.5 millimeters; the front end of the nail body is a first fixed end, and the rear end of the nail body is a first screwing end; the first fixed end is provided with a connecting external thread, and the external diameter of the connecting external thread is 0.2-1.6 millimeters; and at least the end position of the first screwing end is provided with a first force application surface. The invention aims at overcoming the defects of the prior art; the traction / locking element can be used for carrying out traction in time according to the traction opportunity of tooth orthodontics, thereby reducing the discomfort of the oral cavity; and the traction / locking element is very convenient to install and disassemble and is very reliable in traction of teeth.

Description

technical field [0001] The invention belongs to the field of orthodontics, and in particular relates to a traction / locking element, a traction / locking set, an orthodontic bracket, an orthodontic bracket system and a tooth orthodontic method. Background technique [0002] Brackets are an important part of fixed orthodontic technology. They are appliances used to correct tooth alignment deformities. They are directly fixed on the surface of the crown. [0003] In the process of orthodontics, in order to move the teeth, it is necessary to move the teeth to be corrected to the designed direction through the traction parts to achieve the effect of traction. , there are mainly two existing approaches: [0004] The traction hook is integrally welded on the bracket body. The traction hook cannot be disassembled. Because it protrudes from the surface of the bracket body, the traction hook is placed in the patient's mouth along with the bracket body during the whole correction. It b...

Problems solved by technology

[0004] The traction hook is integrally welded on the bracket body. The traction hook cannot be disassembled. Because it protrudes from the surface of the bracket body, the traction hook is placed in the patient's mouth along with the bracket body during the whole correction. Bring obvious discomfort, the movement of the lips will cause the oral mucosa and the buccal surface of the teeth to rub against the traction hook, which is easy to damage the oral mucosa and the buccal surface of the teeth

[0005] Another method is to temporarily insert the traction wire into the bracket body and bend it when traction is required, which will shorten the time the traction hook remains in the oral cavity and reduce the discomfort of the oral cavity; Temporary bending is required. Due to the need to operate the bracket body fixed on the tooth surface, the operating space is small, the field of vision is narrow, and installation and disassembly are very inconvenient, which also affects the effect of traction, so that the force of the traction hook is small and cannot Meeting the needs of orthodontics
