摘要：
A method for electrophoretic deposition of ceramic particles as a green body shaped as a dental appliance, the method comprising the steps of (a) forming a suspension of the ceramic particles in a first polar solvent, the ceramic particles constituting at least about 5 % of the first suspension by weight; (b) passing a direct electrical current through the first suspension, using a deposition electrode (20) shaped as the dental appliance to form a green body; (c) coating the green body with glass particles; and (d) sintering the resultant coated body for obtaining a glass coated all-ceramic dental appliance.
