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.
为了找出能够轻松评估非贵金属/瓷结合强度的方法，采用5种压塑法将Ceramco瓷熔附于铸造的Wiron“S”（直径3mm）上；通过拔出法测量结合强度并比较这些压塑方法。结果如下：（1）传统压塑法与压塑法（压缩压力；472 - 1415kg/cm²）之间未观察到显著差异，Ceramco Paint - O - Pake瓷与Wiron“S”的结合强度约为245 - 369kg/cm²。（2）结合强度随瓷熔合长度的减少而降低。（3）当用牙科石膏固定试件时，结合强度增加了约三倍。
