Description

Sintered nano composite crown

The present invention relates to a non-sintered nanocomposite crown, and more particularly to a non-crackable, non-sintered nanocomposite crown having excellent color appearance, high strength, high elasticity and high ductility.

When implanting teeth, the periodontal ligament must be removed. Therefore, when the user uses the crown to set on the abutment teeth of the implant, it is often difficult to feel the bite force, and often the excessive bite, resulting in poor strength and poor ductility. The crown of the crown is broken.

When the crown of the conventional crown is excellent in appearance color, the strength of the material is generally poor, the elasticity is poor, and the ductility is poor, so that it is easily broken and is not suitable for making a bridge.

At present, there is another kind of crown, which has high strength and high ductility, but is not popular with users due to poor color appearance.

Since the characteristics of the above two crowns are completely different, and the above crown system is made by stacking materials, the above two types of crowns are usually used separately and separately.

Therefore, how to create a crown with excellent color appearance, high strength, high elasticity and high ductility, when set on the abutment teeth of natural teeth or implants, it is not easy to break; and, when the crown is When it is in the shape of a bridge, it is not easy to break. It will be the place where the creative body wants to expose it.

The purpose of this creation is to provide a non-sintered nanocomposite crown with excellent color appearance, high strength, high elasticity and high ductility. It is not easy to be broken when it is placed on the abutment teeth of natural teeth or implants.

Another object of the present invention is to provide a non-sintered nanocomposite crown which is not easily broken when it is in the form of a bridge.

In order to achieve the above and other objects, the present invention proposes a sintering-free nanocomposite crown comprising: a reinforcing body having a groove at the bottom thereof, and the reinforcing body is composed of polyetheretherketone (Peek, polyaryletherketone) and ceramic. And a surface layer covering the surface of the reinforcing body, the surface layer is composed of a composite resin, and the surface layer has at least polymethyl methacrylate (PMMA).

In the non-sintered nanocomposite crown of the present invention, the surface layer further comprises barium glass, amorphous silica, crystalline silica, and trifluorocarbon. Any of ytterbium trifluoride, mixed oxide, barium fluoro borosilicate glass or zirconium dioxide.

In the self-sintering nanocomposite crown of the present invention, the proportion of the ceramic in the reinforcement is 10% to 40%.

In the self-sintering nanocomposite crown of the present invention, the composite resin of the surface layer has a gradation.

In the non-sintered nanocomposite crown of the present invention, a titanium base is further disposed in the groove.

In the non-sintered nanocomposite crown of the present invention, there is a tooth root which is inserted into the titanium base.

In summary, the creation of the sintered nano-composite crown is characterized by the above-mentioned configuration, excellent color appearance, high strength, high elasticity and high ductility, and is set on the abutment teeth of natural teeth or implants. It is not easy to be broken; and when the non-sintered nanocomposite crown is in the form of a bridge, it is not easily broken.

In order to fully understand the purpose, features and effects of this creation, the following specific examples, together with the attached drawings, provide a detailed description of the creation, as explained below:

Please refer to FIG. 1 , which is a schematic view of a first embodiment of the creation of the sintered nanocomposite crown 100 . The leave-free nanocomposite crown 100 comprises a reinforcement 10 and a surface layer 20.

The bottom of the reinforcing body 10 has a groove 11 for fitting to a tooth of a natural tooth or a dental implant, and the reinforcing body 10 is made of a mixture of Peek, polyaryletherketone and ceramic. Wherein, in the reinforcing body 10, the proportion of the ceramic is 10% to 40%, and when the proportion of the ceramic is changed, the strength, elasticity and ductility of the unsintered nanocomposite crown 100 can be changed. Thereby, when the reinforcing body 10 is sleeved on the natural tooth or the abutment tooth, it is not easily broken by the user's excessive bite.

The surface layer 20 covers the surface of the reinforcing body 10, and the surface layer 20 is composed of a composite resin to make the appearance color of the green-free nanocomposite crown 100 excellent, and the surface layer 20 has at least a poly Methyl methacrylate (PMMA, polymethyl methacrylate). Wherein, the surface layer 20 further comprises barium glass, amorphous silica, crystalline silica, ytterbium trifluoride, mixed oxide (mixed oxide) Oxide, any of barium fluoro borosilicate glass or zirconium dioxide.

Further, the composite resin of the surface layer 20 preferably has a gradation to make the appearance of the unsintered nanocomposite crown 100 closer to a real tooth.

In summary, the creation of the sintered nano-composite crown is characterized by the above-mentioned configuration, excellent color appearance, high strength, high elasticity and high ductility, and is set on the abutment teeth of natural teeth or implants. It is not easy to break.

Next, please refer to FIG. 2, which is a schematic view of a second embodiment of the creation of the sintered-free nanocomposite crown 200. The non-sintered nanocomposite crown 200 is substantially identical to the unsintered nanocomposite crown 100, wherein the unsintered nanocomposite crown 200 further has a titanium base 30 disposed in the recess. The titanium base 30 is preferably composed of a titanium-based composite material for accommodating a root 40 or directly on the natural tooth and the abutment tooth.

Next, please refer to FIG. 3, which is a schematic view of a third embodiment of the creation of the sintered-free nanocomposite crown 300. The unsintered nanocomposite crown 300 is substantially the same as the unsintered nanocomposite crown 100, wherein the unsintered nanocomposite crown 300 is formed into a bridge shape. When the user is installed in the oral cavity, even if the occlusion is excessively occluded, the reinforcing body 10 of the non-sintered nanocomposite crown 300 can provide high strength, high elasticity and high ductility, thereby effectively avoiding the sintering-free nanocomposite. The crown 300 is broken; at the same time, the surface layer 20 of the anti-sintered nanocomposite crown 300 has at least polymethyl methacrylate (PMMA), so that the appearance of the unsintered nanocomposite crown 300 has Excellent color and close to the real tooth appearance.

In addition, the reinforcing body 10 and the surface layer 20 are completed by a CAD process, and no need to be sintered, that is, a better combination can be achieved, and the prepared sintered nanocomposite crown 300 is excellent in color at the same time. Appearance, high strength, high elasticity and high ductility.

In summary, the creation of the sintered nano-composite crown is characterized by the above-mentioned configuration, excellent color appearance, high strength, high elasticity and high ductility, and is set on the abutment teeth of natural teeth or implants. It is not easy to break; and when the sintered nano-composite crown is in the form of a bridge, it is not easily broken.
