Abstract
A bonding dental ceramic material and method of use thereof is provided. The bonding dental ceramic material includes at least one network former and between about 8 and 17 percent by weight B.sub.2 O.sub.3. The bonding dental ceramic material does not contain more than 5% by weight of opacifier and/or pigment, and is adapted to bond to titanium or titanium alloy with a bond strength of at least 20 MPa. Preferably the bonding dental ceramic material has a melting point less than 800.degree. C. and includes a fluxing agent. This bonding dental ceramic material is used to make dental crowns and bridges. The bonding dental ceramic material is applied to titanium or titanium alloy and fired at less than 800.degree. C. Then an opaque dental ceramic material including at least one network former and more than 5% by weight of opacifier and/or pigment but less than 5% by weight B.sub.2 O.sub.3 is applied to the bonding dental ceramic material and fired at less than 800.degree. C. Preferably the bonding dental ceramic material has a melting temperature of less than 830.degree. C., and does not have more than 5% by weight pigments and/or opacifiers, or more than 0.5% by weight fluoride.
