Description of the invention: * [Technical field to which the invention belongs] _ι] The tree structure is related to the internal tooth structure of the oral cavity, and particularly relates to a tooth structure having a high chain-strength force. [Prior Art] [0002] Conventionally, denture teeth structures that are used for dental restoration are mostly controlled by casting operations or by computer numerical control (c〇mputer 〇Numerical Control, CNC). The processing method is to form a dental material base that constitutes a structure such as a crown and/or a bridge (crown and bridge prosthodontics). [0003] Referring to the first figure, a conventional denture structure la is shown, which is coupled to a gum 2a. The denture structure ia includes a metal pedestal and is sintered on the metal base. A dentai porcelain part 20a on the seat i〇a. Since the surface of the metal base 10a formed by the casting method is extremely smooth, the bonding force between the metal base i〇a and the dental porcelain portion 20a is poor. Therefore, before the dental ceramic portion 20a is sintered, the surface of the metal base 10a is usually subjected to a sandblasting step, thereby increasing the bonding force between the metal base 10a and the dental ceramic portion 2a. [0004] However, the denture structure produced by the above process has poor precision and often requires multiple corrections and processing modifications, which is time consuming, labor intensive, and costly. Furthermore, after the use of the conventional denture structure 1 for a period of time, the metal base 10a and the dental porcelain portion 2a have poor link strength, causing the metal base 10a to release a part of ions into the human body, which may result in a fear. Carcinogenic risk; in addition, the 'fake denture structure la after a long period of wear and tear, its gold 100113894 Form No. A0101 Page 3 / 17 pages 10020: 201242575 The base 10a will be exposed and oxidized, not only affecting the strength, but also causing The appearance is not beautiful. In view of the above, the present inventors have made great efforts to improve and solve the above-mentioned shortcomings, and have finally made a proposal to rationally and effectively improve the above-mentioned defects. SUMMARY OF THE INVENTION [0006] It is an object of the present invention to provide an oral denture structure having a high chain strength to increase the chain force between the metal base and the dental layer. Another object of the present invention is to provide an oral denture structure with high chain strength to prevent the metal base from being exposed and to increase the aesthetics of the oral denture. [0008] Another object of the present invention is to provide The invention provides a structure of an oral tooth material with high chain strength to prevent ions of the metal base from being released to the human body, thereby reducing the harm of the oral tooth material to human health. [0009] In order to achieve the above object, the present invention is an oral dental structure having a high-strength force for bonding to a dental bed, the high-strength oral dental structure comprising a metal base, a ceramic film layer and a dental porcelain layer, the metal base is sleeved on the gum bed, the metal base comprises an inner surface of the gum bed and an outer surface opposite to the inner surface, and the ceramic film layer is sprayed by atmospheric plasma Sprayed on the surface of the metal base, the dental layer is sintered on the ceramic film layer. [0010] A further object of the present invention is to provide an oral tooth structure with high chain strength, which makes the overall structure of the oral tooth structure more light and thin, but still has sufficient strength to contribute to the denture Accurate alignment to reduce in 100113894 Form No. A0101 Page 4 / Total 17 Page 1002023260-0 201242575 [0011] The amount of dressing of the gum in the process of dental restoration is compared with the prior art 'The present invention utilizes atmospheric plasma The riding method is carried out on the surface of the metal base, which is selected from the group consisting of zirconia (Zr02), alumina and hydroxyapatite (HA). Among them, the ceramic film layer is used to improve the chaining force between the metal base and the dental ceramic layer, so that the overall structure of the dental tooth material is lighter and thinner, but still has sufficient strength to help the denture The precise alignment to reduce the amount of grinding of the gums' reduces the patient's discomfort; in addition, because the ceramic membrane layer can completely cover the metal base, it can effectively isolate the metal base from the outside air and reduce the metal base. Oxidation problem, prevent Exposed base metal aesthetic impact resistance, but also sometimes prevent the oxidation of the metal pedestal release metal ions, to avoid harm to human health, increases the practicality and safety of use. 'Reducing patient discomfort. [0012] [0012] [0012] The detailed description and technical content of the present invention are set forth below with reference to the accompanying drawings. Please refer to the second to fourth figures, which are respectively a schematic view, a cross-sectional view and a schematic view of the structure of an oral tooth material having a high-strength force in the present invention; the oral tooth structure structure with high-strength force of the present invention is used for Combined with a gum 2, the high-strength oral dental structure comprises a metal base 1 and a ceramic film layer 20.

The dental porcelain layer 30 is one of ceramic materials, which is mainly made of silica (Si〇2) and mixed with an appropriate amount of other desired oxides such as quartz and feldspar. The powder is formed by a plurality of processing procedures, and after being mixed in an appropriate amount, it is applied to a metal base (stacking), and finally sintered to form the dental ceramic layer 30. The ceramic film layer 20 generates strength after the sintering process, thereby effectively reducing the thickness requirement of the dental ceramic layer 30 and the metal base 10, making the overall structure of the dental tooth structure 1 lighter and thinner, but still having sufficient strength. . Furthermore, when the thickness of the dental denture structure 1 is thin, it helps the precise alignment of the dentures, so as to reduce the dose of the adhesive 15 used and the amount of grinding of the gum 2, and reduce the patient's dental restoration process. Discomfort in the middle. As can be seen from the partial enlarged view in the third figure, the surface of the ceramic film layer 20 is rough and uneven, thereby providing a good mechanical holding force between the ceramic film layer 20 and the dental ceramic layer 30, and improving both.
