Problems solved by technology

[0002] When implanting, the periodontal ligament must be removed, so when the user uses the crown to fit the abutment tooth of the implant, it is usually difficult to feel the magnitude of the occlusal force, and often overbites, resulting in poor strength and poor ductility fractured crown
[0003] Known crowns with excellent appearance and luster usually have poor strength, poor elasticity and poor ductility, so they are easy to break and are not suitable for making bridges
[0004] At present, there is another kind of dental crown, its material has high strength and high ductility, but it is not popular with users due to the poor color of the appearance

Embodiment Construction

[0019] In order to fully understand the purpose, features and effects of the present invention, now through the following specific embodiments, and in conjunction with the accompanying drawings, the present invention is described in detail, as follows:

[0020] Please refer to figure 1 , which is a schematic diagram of the first embodiment of the sinter-free nanocomposite dental crown 100 of the present invention. The sinter-free nanocomposite dental crown 100 includes a reinforcing body 10 and a surface layer 20 .

[0021] The bottom of the reinforcing body 10 has a groove 11 for sheathing on the abutment teeth of natural teeth or dental implants, and the reinforcing body 10 is made of a mixture of polyaryletherketone (Peek, polyaryletherketone) and ceramics. Wherein, in terms of mass percentage, the proportion of ceramics in the reinforcing body 10 is 10%-40%. When the proportion of ceramics is changed, the strength, elasticity and ductility of the sinter-free nanocomposite...

Abstract

The invention relates to a non-sintering nano-composite dental crown. The non-sintering nano-composite dental crown includes a reinforcing body having a bottom having a groove, wherein the reinforcing body is mixed by polyaryletherketone and a ceramic; a surface layer covering the surface of the reinforcing body, wherein the surface layer is formed by composite resin and at least has polymethyl methacrylate. According to the invention, the non-sintering nano-composite dental crown has an appearance with excellent color, high strength, high elasticity and high ductility, and cannot break when being arranged on a support tooth of a natural tooth or a implanting tooth; and the non-sintering nano-composite dental crown is not prone to fracture while being bridge-shaped.

Description

technical field [0001] The invention relates to a sinter-free nanocomposite dental crown, more particularly to a sinter-free nanocomposite dental crown that is not easy to break, and has excellent color appearance, high strength, high elasticity and high ductility. Background technique [0002] When implanting, the periodontal ligament must be removed, so when the user uses the crown to fit the abutment tooth of the implant, it is usually difficult to feel the magnitude of the occlusal force, and often overbites, resulting in poor strength and poor ductility tooth crown cracked. [0003] If the known crown has a good appearance and luster, its material usually has poor strength, poor elasticity and poor ductility, so it is easy to break and is not suitable for making a bridge. [0004] At present, there is another kind of dental crown, which is made of high strength and high ductility, but it is not popular with users due to its poor color appearance. [0005] Since the ch...
