title: [Bond strength between nonprecious metal alloy and porcelain. Part (1). Bond strength with press condensing method (author's transl)].
abstract: For the purpose of finding out the method which is able to evaluate nonprecious metal/porcelain bond strength easily, Ceramco procelain was fused to casted Wiron "S" (3 mm diameter), by means of 5 types of press condensing methods; the bond strength was measured by pull out method and these condensing methods were compared. Results are follows: (1) No significant difference was observed between conventional condensing method and press condensing method (condensing pressure; 472-1 415 kg/cm2), and the bond strength of Ceramco Paint-O-Pake porcelain to Wiron "S" was about 245-369 kg/cm2. (2) Bond strength was decreased with the decrease of the fused length of procelain. (3) Bond strength was increased approximately three times, when specimens were mounted by dental stone.
