Description

Technical Field

[0001] The utility model relates to the technical field of tooth care, in particular to a composite ultra-thin tooth veneer. Background Art

[0002] Dental veneer is a technology for whitening and repairing teeth. Dental veneer repair is to stick a layer of material similar to normal tooth color on the surface of discolored or damaged teeth to achieve the effect of whitening or repairing. This technology has been widely used in stomatology and is very popular among consumers. Popular dental veneers can be divided into two types: resin veneers and porcelain veneers. They are relatively popular ways of dental beauty. A Chinese patent discloses a dental veneer (authorization announcement number CN214259501U), including a veneer body; two first flow limiting grooves are opened on the surface of the veneer body close to the teeth, and the first flow limiting grooves are opened close to the two sides of the veneer body; the purpose of reducing the escape of glue during the pasting process of the dental veneer is achieved.

[0003] The technical solution of the above patent solves the problem of glue leakage when the veneer is bonded. However, there are other problems in the bonding between the teeth and the veneer. For example, since it is impossible for the veneer and the tooth to fit completely, the glue cannot be completely spread evenly. During the bonding process, there is a high probability that there will be less or no glue in some local areas, which will result in insufficient bonding strength between the two and easy falling off.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0024] Example

[0025] See also Figure 1 to Figure 7 In the present embodiment, a composite ultra-thin dental veneer is provided, including a veneer body 1, a side of the veneer body 1 close to the teeth is provided with a plurality of through holes 4, and a glue storage tank 3 is further provided in the veneer body 1, the through holes 4 are connected with the glue storage tank 3, and at the same time, a filling hole 5 is provided at the top position of one side of the glue storage tank 3, and a sealing structure 6 is provided in the filling hole 5. When in use, glue is applied to the side of the veneer body 1 having the through holes 4, and the sealing structure 6 is not installed in the filling hole 5 of the veneer body 1, and then the veneer body 1 is pressed against the outer surface of the tooth, and the glue is distributed to the surface of the veneer body 1 and the tooth through the force of pressing, so that they can be bonded. In this process, since it is impossible for the veneer body 1 to be completely bonded with the teeth, and further, it is impossible for the glue to be completely evenly distributed, therefore, in the process of bonding the two, there is a high probability that there is less glue or no glue in a local area, which makes the bonding strength between the two insufficient and easy to fall off;

[0026] In the present invention, this problem can be solved by providing the filling hole 5, the glue storage tank 3 and the through hole 4 connected thereto. After the initial bonding, the pressing force is maintained. At this time, glue is refilled from the filling hole 5 by an external device (the external device can be a syringe, etc.). Through the external pressure, the glue is injected into the glue storage tank 3, and then it penetrates outward through the through hole 4 connected thereto, that is, the tooth surface. The glue can be added to the area with less glue or no glue by the pressure, thereby increasing the bonding effect of the glue and avoiding the situation where the bonding effect is poor and it is easy to fall off.

[0027] The sealing structure 6 is threadedly connected to the filling hole 5. After the glue is filled, the sealing structure 6 is screwed to be installed in the filling hole 5 to seal the filling hole 5 and prevent glue leakage.

[0028] The filling hole 5 is set as a threaded hole, and a sealing groove is also provided on the outer side of the filling hole 5. The sealing structure 6 includes a micro screw 61 and a sealing ring 62. The sealing ring 62 is sleeved on the micro screw 61, and the micro screw 61 is threadedly adapted to the thread of the threaded hole. At the same time, the sealing ring 62 is placed in the sealing groove, and the thread head of the micro screw 61 is located in the sealing groove and squeezes the sealing ring 62, so that the sealing effect of the sealing ring 62 can be ensured. At the same time, the thread head is located in the sealing groove so that it will not protrude from the veneer body 1, thereby not affecting the use;

[0029] The back side of the veneer body 1 is also provided with a protective structure 2 that can semi-enclose the teeth. The protective structure 2 can isolate the teeth to be veneered from other teeth, and at the same time, it can also contain excess glue to prevent it from spilling into the mouth;

[0030] The protective structure 2 includes a side plate 21, one side of which is bonded to the veneer body 1, which is convenient for tearing it off, and the side plate 21 is set as a U-shaped structure, and its bottom is sealed, which is convenient for collecting glue. At the same time, a partition 22 is set on the side of the side plate 21 away from the veneer body 1, and the partition 22 interacts with the veneer body 1. When veneer is applied, the bottom of the tooth can be wrapped, thereby preventing the overflowing glue from falling;

[0031] In the utility model, the veneer body 1 is a composite layer, which is composed of multiple materials. A porcelain base layer 11 is set at the center, and a resin layer 13 is set on the outside of the porcelain base layer 11. The resin layer 13 is connected to the porcelain base layer 11 through an adhesive layer 12. Moreover, a porcelain glaze layer 14 is also set on the outside of the resin layer 13. Through the setting of the composite material, the veneer body 1 has multiple advantages and has both the effects of resin veneer and porcelain veneer.

[0032] In the utility model, the glue storage groove 3, the through hole 4, the filling hole 5 and the sealing structure 6 cooperate with each other, so that when the teeth and the veneer are bonded, the glue can be added to the area with less or no glue through the effect of pressure, thereby increasing the bonding effect of the glue, avoiding the situation where the bonding effect is poor and the veneer is easy to fall off.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
