Ceramic bracket

Technical Field

The application relates to the technical field of orthodontic appliances in the department of dentistry, in particular to a ceramic bracket.

Background

The bracket is a common tooth orthodontic appliance and is widely applied to various tooth orthodontics. Brackets typically include self-ligating brackets and non-self-ligating brackets, typically made of metal or ceramic, and self-ligating brackets are currently the most commonly used brackets due to their greater ease of use and stability. The non-self-ligating bracket generally consists of a seat body and a bottom plate on the seat body; the self-ligating bracket generally comprises a cover, a base, a bottom plate on the base, and a self-ligating structure for locking the cover and the base. In the using process, a dentist usually coats an adhesive (usually glue which is harmless to human bodies) on a bottom plate of a bracket, then pastes the bottom plate to a proper position on the surface of teeth, and finally, corrects the teeth to be corrected by matching with an arch wire. Therefore, the correcting effect is greatly related to the structure of the self-ligating bracket.

The application publication number is CN104414760A, and the application date is 2015, 03, 18 and Chinese patent application discloses a slide type tooth orthodontic self-locking bracket, which comprises a bottom plate and a bracket body provided with a groove for placing an arch wire, wherein ligation wings are arranged on two sides of the groove, a slide cover is arranged above the groove, and slide bars are arranged on two sides of the slide cover; the inner side of the ligating wing at one side of the bracket body is provided with a T-shaped chute which is matched with the slide bar of the sliding cover; the lower surface of the sliding cover is provided with a guide block and a limiting groove, the T-shaped sliding groove corresponding to the bracket body is also provided with a guide groove and a protruding limiting pin, and the sliding cover and the bracket body can form self-locking through cooperation and can slide back and forth within a distance limited by the limiting groove.

When the doctor uses the above-mentioned correlation technique to rectify, through the cooperation between sliding closure and the bracket body, realize the good closure of groove to thereby the effect of rectifying is played in the arch wire that makes to be located the groove and can bring comparatively stable effort. However, in the process of adhering the related art, when the self-ligating bracket is adhered to the tooth surface after the adhesive is coated on the smooth bottom plate of the bracket body, a large amount of the adhesive is easily overflowed to the peripheral part of the bottom plate of the bracket body, the adhering effect of the self-ligating bracket is reduced to a certain extent, and the correcting effect of the related art is also reduced to a certain extent.
