Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that titanium has a very active chemical property and has a high affinity for oxygen. At the temperature of porcelain fusion, a loose, porous and poorly adhered oxide film is easily formed on the surface of titanium, which affects the bonding of titanium porcelain. A method of making the embedded material in the casting r

Example Embodiment

[0030] Example 1

[0031] Take SiO 2 5g, grind and place in a porcelain cup for use; pour 35% hydrochloric acid and distilled water into the same beaker at a volume ratio of 1:1, mix well, and pour ethyl orthosilicate into another beaker, and acidify by the mixed hydrochloric acid The volume ratio of water to ethyl orthosilicate is 1:10, and then the acidified water with hydrochloric acid is slowly dropped into the ethyl orthosilicate beaker and stirred fully. The stirred mixture of ethyl orthosilicate and acidified water is continuously added with SiO while stirring 2 Powder (SiO 2 The amount of powder is 3.9-4 times the mass of tetraethyl orthosilicate). After all the addition is complete, continue to stir for 10-15 minutes to make SiO 2 The powder and the mixed liquid are fully reconciled. Coat the compatible inner embedding material on the side of the wax model that has been treated with affinity mist, and solidify at room temperature. Use the titanium professional embedding ...

[0034] Example 2

[0035] Take SiO 2 Powder and 2μm particle size Al 2 O 3 Add 2.5g each of the powder to the ball mill tank, grind for 5 minutes until the two powders are fully mixed; pour 35% hydrochloric acid and distilled water into the same beaker at a volume ratio of 1:1, mix well, and pour aluminate into the other beaker. For calcium cement, the ratio of the mixed hydrochloric acid acidified water to calcium aluminate cement is 1:1, and then the hydrochloric acid acidified water is slowly dropped into the calcium aluminate cement, and fully stirred. The stirred calcium aluminate cement and acidified water mixture is continuously added with mixed SiO while stirring 2 Powder and Al 2 O 3 After adding all the powder and mixing powder, continue to stir for 10-15 minutes to make the powder and the mixed liquid fully mixed. Coat the compatible inner embedding material on the side of the wax model that has been treated with affinity mist, and solidify at room temperature. Use the...

[0038] Example 3

[0039] Take SiO 2 Powder and ZrO 2 2.5g each of the powder, add it to the ball mill tank and grind for 5-10 minutes until the grinding is uniform; pour 35% hydrochloric acid and distilled water into the same beaker at a volume ratio of 1:1, mix well, and pour orthosilicic acid into another beaker. For ethyl ester, the volume ratio of the mixed hydrochloric acid acidified water and the ethyl orthosilicate is 1:10, and the hydrochloric acid acidified water is slowly dropped into the ethyl orthosilicate beaker, and the mixture is fully stirred. The stirred ethyl orthosilicate and acidified water mixture is continuously added with mixed SiO under stirring 2 Powder and ZrO 2 After all the powder is added, continue to stir for 10-15 minutes to make the powder and the mixed liquid fully mixed. Coat the compatible internal embedding material on the side of the wax model that has undergone the affinity mist treatment, and let it dry naturally at room temperature. Use th...

Abstract

The invention discloses a titanium surface casting modification method for reinforcing titanium-porcelain combination strength and belongs to the technical field of titanium-porcelain metal-porcelain. The method comprises the steps of: selecting one or a plurality of silicon dioxide, aluminum oxide, chromium oxide, low-smelting bonding porcelain powder, high-smelting bonding porcelain powder, screen color porcelain powder and dentin porcelain as basic ingredients of an internal embedding material; regulating the internal embedding material to gel substance through ethyl orthosilicate acidified by hydrochloric acid, or calcium aluminate cement and distilled water and water; wetting a casting wax pattern through amiable fog, coating the internal embedding material on the side to be fused with porcelain, and curing the internal embedding material at room temperature; embedding the internal embedding material through a titanium casting; and commonly casting the internal embedding material. The method disclosed by the invention forms an oxidization shield when the titanium porcelain is formed and the reaction gradient mixed layer and the glass phase in the porcelain powder form chemical combination to improve the titanium-porcelain combination strength.

Description

technical field [0001] The invention belongs to the technical field of titanium-ceramic metal ceramics, and relates to a preparation method of a titanium surface casting modified internal embedding material and a preparation method of a titanium-ceramic reaction intermediate mixed layer, so as to enhance the bonding strength of titanium-ceramic and popularize titanium-ceramic Application of metal porcelain in dental clinic. Background technique [0002] Metal titanium and its alloys have attracted much attention because of their light weight, good biocompatibility and biosafety, and the price is far lower than that of precious metals. They have been widely used in oral implants, fixed, removable denture restorations, and complete dentures. Base, artificial joints and internal fixed splints, etc. However, the application of oral titanium restorations, especially fixed titanium porcelain restorations, is limited to a certain extent. This is because the chemical properties of ...
