More Information
Summary:Disclosed are a dental gradient color-resin ceramic restoration material and a preparation method thereof. The method includes: preparing at least two paste materials with different colors, respectively dispersing the paste materials with different colors at a certain speed and under a vacuum of -0.01-0.1 MPa to obtain at least two granular materials with different colors having an average size of 0.1 mm to 5 mm; spreading the at least two granular materials with different colors to be flat in a mould in sequence to obtain at least two layers, and then tightly combining the at least two layers at a pressure of 0.5-5 MPa to obtain a semi-finished product of a gradient color-resin ceramic restoration material; polymerizing and curing the semi-finished product at 60-200° C. and 2-50 MPa to obtain a multilayer gradient color-resin ceramic restoration material.
