| titleOfInvention | Zirconia false tooth with gradient mechanical property and photocuring dynamic forming method thereof |
| abstract | The invention discloses a zirconia false tooth with gradient mechanical property and a photocuring dynamic forming method thereof. The method is based on three-dimensional photocuring molding or digital light processing molding, and realizes gradient change of the porosity of the occlusal surface and the matrix part of the denture by dynamically controlling process parameters in the molding process. And sintering the formed biscuit at high temperature to form a ceramic net structure with gradient porosity, and filling water-based zirconia slurry into pores through pressurization and permeation. The nanometer zirconia particles contained in the penetrating fluid after the intermediate-temperature secondary sintering are combined with the ceramic net structure to form a structure with alternate density, so that the mechanical property of the occlusal surface of the false tooth is reduced, and the excessive abrasion of the opposite side natural teeth in the oral cavity is avoided. The invention changes the limitation that the traditional gradient functional ceramic false tooth preparation process needs to adopt different components of ceramic slurry, and can effectively solve the problem that the false tooth prepared from zirconia material causes excessive wear to the natural teeth on the opposite side in the oral cavity due to over-high hardness. |
