Abstract

The invention relates to a polycrystal alumina artificial dental root and a preparation method thereof. The artificial dental root is prepared from the following components in parts by mass: 25-45 parts of polycrystal alumina, 15-28 parts of poly(methyl methacrylate) resin, 10-20 parts of polyacrylonitrile fibers, 5-13 parts of teflon fibers, 5-15 parts of barium titanate, 3-10 parts of silicon dioxide, 3-10 parts of kaolin, 0.1-0.5 part of cadmium yellow, 0.5-3.5 parts of bisphenol A- glycidyl dimethacrylate, 0.2-1 part of cyclohexanone resin, 0.3-1.2 parts of apricot oil and 0.1-0.4 part of zinc oxide. The artificial dental root has excellent adhesion with gum and similar color with teeth, has an antibacterial effect, cannot easily cause infection after being implanted into an alveolar bone, can firmly form a related tissue in the alveolar bone after a period of time, and has good biocompatibility.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a polycrystalline alumina artificial tooth root and a preparation method thereof. Background technique [0002] Dental root refers to the root of the tooth, the part where the tooth is connected to the gum. Artificial tooth roots are tooth roots made of artificial materials. If the patient is only damaged by a single tooth or cannot be extracted due to disease, but the gum bed is still intact, artificial tooth roots can be implanted on the human alveolar bone to make it suitable for the composition. [0003] Polycrystalline alumina, that is, corundum, is strong and easy to process, and is used to make artificial hip joints, artificial bones, artificial tooth roots and joints. [0004] At present, the adhesion between the existing artificial tooth roots and the gums on the market needs to be improved, and there is still a certain risk of infection, and they cannot be f...
