This application discloses a dental prosthesis and its fabrication method. The method includes: fabricating a gold alloy inner crown using a lost-wax casting process; fabricating a glass-ceramic outer crown using 3D printing or CAD / CAM cutting equipment; sequentially performing surface sandblasting, applying a metal surface treatment agent, and applying a light-curing adhesive on the bonding surface of the gold alloy inner crown; treating the bonding surface of the glass-ceramic outer crown with acid etching and a silane coupling agent; and finally bonding and fixing the glass-ceramic outer crown to the gold alloy inner crown using adhesive resin. This application uses a cold bonding system to achieve the molding of the gold alloy inner crown and the glass-ceramic outer crown, replacing the traditional high-temperature sintering process. This eliminates the potential for thermal stress at the source, avoiding problems such as porcelain chipping, inner crown oxidation, and edge deformation caused by high temperatures, while preserving the mechanical properties of the gold alloy and the aesthetic properties of the glass-ceramic.

The present application discloses a mineralization material for treating dentin hypersensitivity and promoting epitaxial growth of enamel, and its use, which comprises, by weight, 5-72 parts of a membrane-forming protein or PEGylated membrane-forming protein, 4-67 parts of a water-soluble disulfide exchanger, and 1-21 parts of a pH adjuster. The present application first proposes using a non-toxic disulfide exchanger (e.g., cysteine ​​(Cys)) to react with a membrane-forming protein or PEGylated membrane-forming protein, so that when a protein nano-coating layer with a mineralization-regulating function is formed, a large amount of high molecular weight protein aggregates that block dentin pores are not generated, the permeability is better, and the protein nano-coating layer can penetrate deeper into the already exposed dentin pores, reaching a depth of 200-500 μm (the blocking depth of the protein coating layer reacting with TCEP is only about 40 μm), and can reach the recesses of pits and fissures.
