Ceramic material for mouth rehabilitation and preparation method thereof

Abstract

The invention discloses a ceramic material for mouth rehabilitation and a preparation method thereof, and relates to the technical field of mouth rehabilitation. The ceramic material comprises the following components in parts by weight: 45-65 parts of zirconium oxide, 30-40 parts of aluminum oxide, 10-20 parts of zinc oxide, 5-10 parts of aluminum borate, 10-20 parts of borax, 10-15 parts of rare earth oxide, 5-10 parts of silicon dioxide, 10-20 parts of sodium fluoride, 5-10 parts of resorcinol monobenzoate, 4-8 parts of a thickening agent and 4-8 parts of a coagulant. The zirconium oxide is used as a main material, the aluminum oxide is used as an auxiliary material, and the zinc oxide and the silicon dioxide are added, so that the strength and the toughness of the prepared ceramic material are ensured, the defect that the traditional ceramic material is brittle and easy to break is overcome, and the clinical success rate is improved. Meanwhile, a certain sterilization effect is achieved through sodium fluoride. Through resorcinol monobenzoate, the light stability of the ceramic material is improved, and the attractiveness of the ceramic material is improved. Gaps generated in the ceramic sintering process are filled with the thickening agent and the coagulant, the defects of the dental restoration are reduced, and the product strength is improved.

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a ceramic material for oral restoration and a preparation method thereof. Background technique [0002] Oral restoration refers to the treatment of soft and hard tissue defects in the oral cavity and maxillofacial region using artificial restorations, and also includes the treatment of periodontal disease and temporomandibular joint disease through restoration methods. With the improvement of living standards and the diversification of diet, there are more and more patients with tooth loss caused by dental caries, periodontitis and tooth damage in my country. Ceramic material is considered to be the best material to match the appearance of human teeth, and its excellent aesthetics, wear resistance, and color stability make it the most common oral restoration material. At present, ceramics are mainly used in oral restoration in the form of porcelain-fused-to-...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of ceramic material for dental restoration and its preparation method, by using zirconium oxide as the main, aluminum oxide as supplementary, zinc oxide and silicon dioxide are also added at the same time, to ensure the strength and strength of the ceramic material. Toughness improves the lack of brittleness of traditional ceramic materials and improves the clinical success rate. At the same time, sodium fluoride has a certain bactericidal effect, and resorcinol monobenzoate improves the potency of ceramic materials. Light stability, increase its aesthetics, fill the gaps generated during the sintering process of filled ceramics with thickeners and coagulants, reduce the defects of oral restorations, increase product strength, and solve the existing problems of insufficient strength and insufficient aesthetics
