The difficulties of successfully repairing the fractured porcelain of porcelain fused to metal fixed prostheses is described. When fractured porcelain involves the gingival margin of a crown, then the repair may involve bonding to porcelain, and metal, and root dentin. The merits of Den-Mat products for bonding to these surfaces are explained.
A clinical case report is presented in which a Cerinate porcelain “shield” (a partial veneer) is bonded over the facial surface of a tooth root and a crown with fractured porcelain at the gingival. The procedure is simple to perform and the results are excellent.
