PCT No. PCT/GB91/01141 Sec. 371 Date Jan. 12, 1993 Sec. 102(e) Date Jan. 12, 1993 PCT Filed Jul. 10, 1991 PCT Pub. No. WO92/00935 PCT Pub. Date Jan. 23, 1992.A method of preparing the fitting surface of a dental ceramic body for subsequent bonding to a tooth with, for example, glass polyalkenoate and resin based cements, including the step of depositing, by a vapour phase deposition technique, directly onto the fitting surface of the ceramic body a strongly adherent coating of an inorganic substance such as tin oxide at a thickness ideally less than 2 microns, the coating being reactive with the cement to provide a durable chemical bond therewith which is not subject to chemical degradation in the oral environment and which will not compromise the aesthetics of the associated dental restoration. |
