Drawings

Fig. 1 is a schematic view of the overall structure of a dental tray.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the individual cemented denture base for orthodontics comprises a base body 1 and a bottom plate 2; the bottom plate 2 is clamped between the denture base body 1 and teeth; a reinforcing groove 3 is formed in one side, facing the teeth, of the bottom plate 2; and the reinforcing groove 3 is filled with a bonding agent.

The structure that the base plate 2 is additionally arranged between the traditional denture base body 1 and the teeth 9 can overcome the problem of difficult surface processing caused by material factors of the denture base body 1, and the surface of the base plate 2 is customized and adjusted according to the surface contour of a target tooth, so that the base plate 2 can be more attached to the teeth than the traditional denture base body 1, better bonding strength is obtained under the condition of trying the same bonding agent, and the risk of falling of the denture base is reduced; meanwhile, the reinforcing groove 3 enables the adhesive in the reinforcing groove to form a resin bulge similar to enamel adhesion after curing, so that the rooting effect is achieved, compared with the scheme that the adhesive is only arranged at the joint interface at present, the firmness of the reinforcing groove is greatly improved, the orthodontic device formed by the denture base body 1 and the bottom plate 2 can be firmly adhered to teeth integrally, and a specific correcting effect is exerted.

The surface contour shape of the side of the base plate 2 facing the teeth is made by 3D printing.

Prepare bottom plate 2 through 3D printing, can ensure the accurate laminating of surface profile after obtaining the space scanning model data on target tooth surface, furthest improves the laminating degree.

The reinforcing groove 3 comprises a straight groove 31 and an inner expanding groove 32; the cross-sectional shape of the straight groove 31 is the same everywhere along the depth direction; the cross-sectional area of the inside of the inner expanding groove 32 is larger than that of the opening; the inner expanding grooves 32 are distributed in the central area of the surface of the bottom plate 2; the straight grooves 31 are distributed in the edge area of the surface of the base plate 2.

The difference between the two groove structures is that the straight groove 31 can improve certain bonding strength and can also limit the overall bonding improvement amplitude because the solidified bonding agent is easy to fall off integrally along the groove depth direction; the inner expanding groove 32 is equivalent to a shape with a larger section than that of the opening provided in the groove, and the whole adhesive is prevented from being pulled out because the notch is smaller after the adhesive is solidified, so that the improvement effect on the adhesive strength is obviously improved; the effect of using these two kinds of groove structures together lies in, and bottom plate 2 surface central area's internal expanding groove 32 can effectively guarantee that the whole adhesive strength between bottom plate 2 and the tooth reaches higher level, and the straight groove 31 of bottom plate 2 surface edge is convenient for follow the edge and 2 perk bottom plate when providing relatively less adhesive force to reduce the separation degree of difficulty between bottom plate 2 and the tooth, show the speed of taking off that promotes the facing.
