The invention discloses an aluminosilicate auxiliary deposition silver coating planting abutment ceramic material and a preparation method thereof to solve the problem in the prior art that a ceramicabutment is not subjected to antibacterial treatment. The preparation method comprises the steps of coating a layer of aluminosilicate on the surface of a zirconia ceramic sheet and baking to obtain asintered aluminosilicate coated ceramic sheet; immersing the sheet in a silver nitrate solution for ultrasonic water bath impregnation away from light; after the impregnation, taking out the aluminosilicate coated ceramic sheet and baking to reduce the silver nitrate impregnated on a coating of the aluminosilicate coated ceramic sheet in situ to obtain the aluminosilicate auxiliary deposition silver coating planting abutment ceramic material. The material has the advantages of being scientific in design and convenient to operate, has both aesthetics and antibacterial property, and can stablyexert the antibacterial action for a long period. The preparation method is simple, low in cost and high in safety.
