Problems solved by technology

[0003] Polymethyl methacrylate is a commonly used restorative material in stomatology. It is mainly used in removable denture bases, artificial teeth, temporary crowns, bridges, individual trays, orthodontic removable appliances, traditional jaw pads, and traditional retainers. It has the advantages of wide indications, low price, no harm to adjacent teeth, and easy repair. It is a commonly used repair material at present, but its wear resistance is poor and its strength is insufficient, which often causes excessive wear, aging and fracture of dentures and shortens its lifespan. Generally within 5-8 years; at the same time, it has no antibacterial properties and is prone to caries, causing gingivitis, periodontitis and oral soft tissue inflammation, etc., which brings inconvenience to patients during use.

Abstract

The invention discloses a dental denture material, which comprises the following components in parts by weight: 4-8 parts of yttrium oxide, 0.1-0.4 parts of alumina, 4-8 parts of zirconia, 30-50 of polymethyl methacrylate, 0.5-1.2 parts of a polyvinyl alcohol aqueous solution, 0.8-1.0 parts of an allicin extract, and 5-8 parts of a lauryl betaine. The novel dental denture material by the preparation method can effectively solve the problems of easy cracking and poor antibacterial performance of a traditional denture base, greatly improves the mechanical performance of the denture, and meets the requirements of doctors and patients for dentures. The addition of the allicin extract and lauryl betaine in the raw materials has antibacterial effect, so that the prepared denture has an antibacterial effect on the basis of satisfying the mechanical properties, and effectively avoids occurrence of caries, gingivitis, periodontitis and the oral soft tissue inflammation to ensure the health of the oral cavity; and the use of polymethyl methacrylate as the raw material reduces the cost of the material and further increases the mechanical strength. The preparation process of the invention is simple and has wide application prospects.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an oral denture material and a preparation method thereof. Background technique [0002] Dentures are used for the restoration and replacement of missing, missing or dentition teeth, as well as for oral health and orthodontics. With the improvement of people's living standards and the development of stomatology, the clinical demand for high-tech oral material products has increased significantly. 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. [0003] Polymethyl methacrylate is a commonly used restorative material in stomatology. It is mainly used in removable denture bases, artificial teeth, temporary crowns, bridges, individual trays, orthodontic removable appliances, traditional jaw pads, and traditional retainers. It has...
