Abstract
Description
Technical Field
[0001] This utility model relates to the field of dental restoration technology, specifically a high-strength and durable dental all-ceramic fixed bridge. Background Technology
[0002] A fixed bridge is a type of fixed prosthesis. It mainly uses the natural teeth at one or both ends of the edentulous space as abutment teeth (similar to bridge abutments). The retainer of the prosthesis is made on the abutment teeth and connected to the artificial teeth as a whole. The prosthesis is cemented to the abutment teeth with cement. The patient cannot remove it by himself.
[0003] Traditional dental all-ceramic fixed bridges have a long span, and under the action of occlusal force, huge tensile stress is generated in the middle of the bridge body (especially at the joints). Since these tensile stresses cannot be dispersed, the fixed bridge is prone to cracking, which affects its service life. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows:
[0006] A high-strength and durable dental all-ceramic fixed bridge includes a restorative mechanism and a reinforcement mechanism. The restorative mechanism includes a natural tooth, a removable crown fitted onto the top of the natural tooth, and a reinforcement mechanism. The reinforcement mechanism includes multiple micropores on the outer surface of the natural tooth, multiple deep holes on the inner wall of the crown, a bionic mesh frame interfering between the natural tooth and the crown, and multiple rectangular openings on the bionic mesh frame. The multiple rectangular openings are respectively located between the multiple micropores and the multiple deep holes.
[0007] By adopting the above technical solution, the bionic mesh frame and the dental brace are sequentially placed on the outside of the natural teeth. The bionic mesh frame tightens the dental brace and the natural teeth, improving the stability of the dental brace installation. At the same time, when the dental brace is under pressure, the bionic mesh frame disperses the stress, thereby reducing the probability of dental brace damage and ensuring its service life.
[0008] In a preferred embodiment, the present invention can be further configured such that: a flat surface is provided on the natural tooth, and the bottom of the dental brace fits against the flat surface.
[0009] In a preferred embodiment, the present invention can be further configured such that all bends of the braces are curved surfaces.
[0010] In a preferred embodiment, the present invention can be further configured such that: multiple deep holes are located outside multiple micro holes, and both the deep holes and micro holes are frustum-shaped and facing each other.
[0011] In a preferred embodiment, the present invention can be further configured such that the volume of the deep hole is greater than the volume of the micro hole, and the interior of the deep hole is connected to the interior of the micro hole.
[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0013] 1. In this utility model, the bionic mesh frame and the dental brace are sequentially placed on the outside of the natural teeth. The bionic mesh frame tightens the dental brace and the natural teeth, improving the stability of the dental brace installation. At the same time, when the dental brace is under pressure, the bionic mesh frame disperses the stress, thereby reducing the probability of damage to the dental brace and ensuring its service life.
[0014] 2. In this utility model, after the bionic mesh frame and braces are installed, resin is injected into the micropores and deep holes. The two resins are connected and solidified at the rectangular opening, thus forming a mechanical locking of the "resin protrusion", which makes the bionic mesh frame installation more secure. This forms a complementary fixed combination, making the braces less likely to fall off. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-strength and durable all-ceramic dental fixed bridge.
[0025] Example 1:
[0026] Combination Figure 1-4 As shown, the present invention provides a high-strength and durable dental all-ceramic fixed bridge, including a restoration mechanism 100 and a reinforcement mechanism 200. The restoration mechanism 100 includes a natural tooth 110 and a dental crown 120 that is movably fitted onto the top of the natural tooth 110.
[0027] The reinforcement mechanism 200 includes a plurality of microholes 210 formed on the outer surface of the natural tooth 110, a plurality of deep holes 220 formed on the inner wall of the dental brace 120, a bionic mesh frame 230 interference-fitted between the natural tooth 110 and the dental brace 120, and a plurality of rectangular openings 240 formed on the bionic mesh frame 230, wherein the plurality of rectangular openings 240 are respectively located between the plurality of microholes 210 and the plurality of deep holes 220.
[0028] Furthermore, multiple deep holes 220 are located outside multiple micro holes 210. Both the deep holes 220 and the micro holes 210 are set in a frustum shape and are arranged opposite each other. With this layout design, the resin solidified inside the two is not easy to fall off from the micro holes 210 and the deep holes 220, which greatly improves the connection strength of the two resins solidified together.
[0029] Furthermore, the volume of the deep hole 220 is greater than the volume of the micro hole 210, and the interior of the deep hole 220 is connected to the interior of the micro hole 210. With this structural design, the resin in the micro hole 210 and the deep hole 220 can be connected in a structural manner.
[0030] Example 2:
[0031] Combination Figure 2 As shown, based on Embodiment 1, the natural tooth 110 is provided with a plane 300, and the bottom of the dental crown 120 is fitted with the plane 300. The plane 300 is provided to ensure that the dental crown 120 can be sealed and fitted with the natural tooth 110.
[0032] Example 3:
[0033] Combination Figure 1-3 As shown in the above embodiment, the multiple bends of the braces 120 are all set as curved surfaces, which can improve the comfort of using the braces 120 in the oral cavity.
[0034] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the bionic mesh frame 230 and the dental crown 120 are first placed on the outside of the natural tooth 110. The bionic mesh frame 230 can tension the dental crown 120 and the natural tooth 110, enhancing the installation firmness of the dental crown. Subsequently, resin is injected into the micropore 210 and the deep hole 220. The two resins connect and solidify at the rectangular opening 240, forming a "resin protrusion" mechanical lock, further stabilizing the bionic mesh frame 230. Thus, the two form a complementary and fixed combination. Then, when the dental crown 120 is subjected to biting pressure, the bionic mesh frame 230 can effectively prevent stress concentration, thereby reducing the risk of damage to the dental crown and ensuring its service life.
[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
