Abstract

The invention discloses entrapping powder being excellent in thermal stability, for preparing false teeth. The entrapping powder being excellent in thermal stability, for preparing false teeth, comprises the components in parts by weight of 40-60 parts of polymethylmethacrylate, 25-30 parts of zirconium oxide, 1-4 parts of cerium oxide, 1-4 parts of yttrium oxide, 0.5-0.8 part of aluminum oxide, 2-3 parts of a dispersing agent, 1-1.5 parts of a peppermint leaf alkene extract, 4-8 parts of apatite, 3-5.7 parts of a green tea extract and 2.5-3 parts of diallyl sulfide. The zirconium oxide, the yttrium oxide and the cerium oxide are added, so that the entrapping powder has good thermoplasticity, and provides convenience for the hot moulding process of the false teeth. The diallyl sulfide is added, so that the entrapping powder has good sterilizing effects, can restrain growth of bacteria in the oral cavity, and is favorable for health of users. The peppermint leaf alkene extract is added,so that the breath of people in breathing can be fresh when the entrapping powder is in the oral cavity, and the entrapping powder is comprehensive. The apatite and the green tea extract are added, so that the false teeth have the effects of resisting acid and preventing decay, and the service life of the false teeth is prolonged.

Description

technical field [0001] The invention relates to the field of denture materials, in particular to an embedding powder with excellent thermal stability for preparing dentures. Background technique [0002] Dentures are often referred to as "dentures". In medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth. Dentures are divided into two types: removable and fixed. Fixed dentures cannot be taken and worn by patients themselves. , while removable dentures can be easily removed and worn by the patient. During removable dentures, patients can remove and wear their own dentures, which are suitable for the situation where most teeth are missing in the whole mouth and few remaining teeth are present. However, there are also many inconveniences such as low chewing efficiency, and patients need to take off and clean after meals. Fixed dentures use the healthy teeth on both sides of the missing teeth as support to fix the dentures ...
