Alumina is an ideal material with good cost performance. In-Ceram powder slurry is usually used to coat plastic crowns (in-ceram technology). It is made into paste by distilled water, coated on the outer surface of prefabricated aluminum ceramic bottom layer, infiltrated and fired at 1 100 degrees Celsius, and infiltrated into the micropores of alumina bottom layer by capillary action to form a uniform network cross-linked structure, which can improve the bending strength of alumina bottom layer. So as to obtain a glass-alumina two-phase composite material with high strength and toughness, which is locked and evenly distributed. Its strength is as high as 400 ~ 600 MPa, and its fracture toughness is 4.49 MPa m1/2. It is a high-tech ceramic material suitable for dental restoration technology. Compared with traditional dental restoration ceramics, its strength has been improved by more than 5 times. Therefore, alumina material can be said to have the aesthetic feeling of all-ceramic crown, and its hardness is close to that of metal porcelain crown. Comparison of these two materials: light transmittance: alumina >; Zirconia hardness: zirconia >; Alumina price: zirconia > alumina The above statement can clearly explain the cost performance between the two. You can choose carefully according to your own needs and economic situation.
