Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent. It is only stated that the terms of orientation such as up, down, left, right, front, back, inner, outer, etc. used in this document or the imminent present utility model, are used only with reference to the drawings of the present utility model, and are not meant to be limiting in any way.
As shown in fig. 1, the embodiment of the utility model provides an orthodontic bracket easy to bond, which comprises a bracket body, wherein one side of the bracket body is provided with a groove 2 and a bracket wing 3, the groove 2 is arranged in the middle of the bracket body and transversely penetrates through the bracket body, the bracket wing 3 is arranged at two sides of the groove 2, one side of the bracket body is provided with a bracket substrate 1 fixed with a tooth surface, the surface of the bracket substrate 1 is inwards recessed to form an adhesive embedded part 4, the surface of the bracket substrate 1 can be tightly attached to the flat incisor tongue side, the adhesive strength reduction caused by incomplete contact between teeth and the bracket substrate 1 can not occur, by arranging the adhesive embedded part 4, on one hand, the adhesive can effectively penetrate in to enhance the adhesive performance, on the other hand, after the adhesive is cured, the adhesive is formed into a tight bicontinuous phase with the adhesive embedded part 4, the adhesive strength is further improved, and meanwhile, the strength of a bonding layer is also ensured.
The bracket body is formed integrally, and preferably, the bracket body can be formed by integral 3D printing. The 3D printing can achieve direct additive forming of orthodontic bracket bodies, thereby shortening development time of new products.
The adhesive embedding part 4 is one or more of a hemisphere, a cylinder, a prism and a prismatic table. Because the orthodontic bracket provided by the utility model is integrally formed by 3D printing, the shape of the adhesive embedded part 4 can be designed and processed in complex shapes besides a simple structure without the limitation of laser cutting processing technology, and the shape of different adhesive embedded parts 4 can be designed according to the conditions of different patients. FIGS. 2-4 illustrate various embodiments of the present utility model, as shown in FIG. 2, wherein hemispherical adhesive inserts 41 facilitate the flow of adhesive, and cylindrical adhesive inserts may also provide for uniform flow of adhesive; as shown in fig. 3, the contact area between the prismatic adhesive embedding portion 42 and the bracket base 1 is larger, which is advantageous for improving the bonding stability; the combination of the various shapes is advantageous in further improving the adhesive stability, and as shown in fig. 4, the shape of the adhesive embedding portion 43 is a combination of a land and a prism, and since the bottom area of the land is larger than that of the prism, the adhesive is not easily removed from the adhesive embedding portion 4 after curing.
The adhesive embedded parts 4 are uniformly arranged on the surface of the bracket base 1, and each area of the bracket base 1 can be well adhered to teeth through the uniformly arranged adhesive embedded parts 4.
The bottom 21 of the slot 2 is disposed obliquely with respect to the bracket base 1, and the side walls 22 of the slot are disposed perpendicular to the bottom 21 of the slot. Because the teeth of a person have a certain included angle with the vertical direction, the included angle between the bottom 21 of the groove 2 and the bracket base 1 can adapt to the tooth structure of most people. Preferably, the included angle is 7-9 °. When the arch wire is placed in the groove 2 which is obliquely arranged, the torsion angle of the arch wire is smaller relative to the groove which is arranged in parallel in the correcting process, and the arch wire cannot deform too quickly, so that the frequency of replacing the arch wire can be reduced.
Further, the thickness of the bracket base 1 is 0.4-0.8mm, if the thickness of the bracket base 1 is too large, the placement and fixation of the orthodontic bracket in the oral cavity are not facilitated, and if the thickness of the bracket base 1 is too small, the strength of the bracket base 1 is affected, and the improvement of the bonding strength with teeth is not facilitated. The thickness of the adhesive embedding part 4 is 0.2-0.5mm, and the area of the adhesive embedding part 4 occupies 1/3-3/5 of the area of the bracket base 1. By defining the thickness ratio and the area ratio of the adhesive embedding portion 4 to the bracket base 1, the fixing strength of the enamel surface to the bracket base 1 can be ensured.
One of them holds in palm is equipped with traction portion 5 on the groove wing 3, and traction portion 5 stretches out towards the root of tooth direction, and traction portion 5's top is equipped with spacing ball 6, and traction portion 5 is used for fixed traction wire, realizes tooth movement correction through the tensile effect of traction wire, and spacing ball 6 can prevent that the traction wire from deviate from.
The end parts of the bracket wings 3 are bent towards the bracket base 1 to form guide hooks 7, and the guide hooks 7 facilitate the penetration and fixation of ligature wires. The bracket wing 3 can be a single-wing structure, a double-wing structure or a three-wing structure, and the bracket wing is specifically selected according to practical situations.
While the foregoing is directed to the preferred embodiments of the present utility model, it will be appreciated by those skilled in the art that changes and modifications may be made without departing from the principles of the utility model, such changes and modifications are also intended to be within the scope of the utility model.
