Abstract

The invention discloses an antibacterial ceramic material for preparing a false tooth and a preparation method thereof. The ceramic material is prepared from yttrium oxide, aluminum oxide, zirconium oxide, lauryl betaine, a polyvinyl alcohol solution and allicin extraction liquid. The preparation method comprises the following steps: S1, taking yttrium oxide, aluminum oxide, zirconium oxide, lauryl betaine, the polyvinyl alcohol solution and the allicin extraction liquid in parts by weight and grinding yttrium oxide, aluminum oxide and zirconium oxide in a ball mill for 2-5 hours to obtain a first mixture; S2, putting the first mixture into a crucible, heating the crucible to 1800-2500 DEG C and insulating heat for 1-3 hours, and when the first mixture is cooled to 40-60 DEG C, adding the allicin extraction liquid, lauryl betaine and the polyvinyl alcohol solution and stirring to obtain a second mixture; and S3, pouring the second mixture into a die and drying in vacuum for 1-4 hours to obtain the antibacterial ceramic material. The ceramic material disclosed by the invention is wear-resistant, acid-alkali-resistant, high in hardness and low in preparation cost.

Description

technical field [0001] The invention relates to a material for dentures, in particular to an antibacterial ceramic material for denture preparation and a preparation method thereof. Background technique [0002] The development of oral restoration is inseparable from the development of oral materials and techniques. Denture restoration materials mainly include ceramics, resins and metal materials. Now clinically, nickel-chromium alloy materials are often used to make dentures, but many heavy metals are harmful to the human body in the oral cavity for a long time, and some people are allergic to nickel, which is even more harmful to health. Traditional glass-ceramic and alumina-based ceramic materials are not strong enough and brittle, easy to break, which limits their application in oral restorations. [0003] With the rapid development of current oral restorative technology, all-ceramic materials have become the most widely used dental materials due to their good biocomp...
