Detailed Description

The present application is described in further detail below with reference to the attached drawings.

Referring to fig. 1 and 2, the present application provides a dental veneer comprising a veneer body 1; two first flow limiting grooves 2 are formed in the surface, close to the teeth, of the veneering body 1, the two first flow limiting grooves 2 are respectively formed in the two sides, close to the veneering body 1, of the veneering body, and the extending direction of the tooth veneering is parallel to the side edges of the veneering body 1; in the process of pasting the tooth facing, after the glue is smeared on the surface of the tooth facing close to the tooth, the tooth facing needs to be pressed towards the direction close to the tooth, so that the glue can be spread between the facing body 1 and the tooth surface. Glue is to the trend of diffusion all around this moment, and first limit chute 2 can store glue to the in-process of diffusion all around at glue, and then hinders glue and extrude from wainscot body 1's edge, and then reduces the tooth wainscot on the in-process glue of pasting overflows to adjacent tooth.

Referring to fig. 2, a second flow limiting groove 3 is horizontally arranged on the surface of the veneering body 1 close to the teeth, the bottom edge of the second flow limiting groove 3 close to the veneering body 1 is arranged, and the extending direction of the second flow limiting groove 3 is parallel to the bottom edge of the veneering body 1; when glue between wainscot body 1 and the tooth surface was too much, glue was because of the extrusion to the direction diffusion that is close to the gum, and this part glue can be stored to second flow limiting groove 3 to hinder this part glue to the direction escape that is close to the gum, and then reduce glue and overflow to the gum.

Referring to fig. 2, one end of the first flow limiting groove 2 close to the second flow limiting groove 3 extends to the second flow limiting groove 3, and the first flow limiting groove 2 is communicated with the second flow limiting groove 3; like this, when the inside glue of first limit chute 2 was more, glue can be followed first limit chute 2 inside and escaped to the direction that is close to the gum because of the dead weight, and second limit chute 3 and then intercepts this part glue to further reduce glue and escape to the gum on.

Referring to fig. 2, a plurality of glue storage grooves 4 which are uniformly distributed on the surface of the veneering body 1 are formed on the surface of the veneering body 1 close to the teeth, and the glue storage grooves 4 are formed in an area enclosed by the first flow limiting grooves 2 and the second flow limiting grooves 3; thus, when the glue is smeared on the veneering body 1, a part of the glue can be stored in the glue storage tank 4, when the tooth veneers are required to be pasted on teeth, the tooth veneers are pressed towards the direction close to the surfaces of the teeth, and the glue in the glue storage tank 4 is extruded and diffused between the veneering body 1 and the surfaces of the teeth, so that the glue dosage for pasting the tooth veneers can be increased, and the veneering body 1 can be more firmly pasted on the surfaces of the teeth; in addition, when the glue between the veneering body 1 and the tooth surface is too much, the glue can also escape into the glue storage groove 4, and further the glue is reduced to escape from the veneering body 1.
