title: [Effect of different thermal properties and different pontic frame designs to breaking strength of metal-porcelain bridges].
abstract: Bonding of two different materials, like porcelain and metal, is affected by many factors during the firing process. Thermal compatibility is one of the prerequisites in metal-porcelain bonding. Plus, the geometric differences are also accepted as an effect in thermal compatibility. In this study it is observed that the metal framework designs that we used had no effect on the strength of porcelain; however the thermal compatibility of metal and porcelain had an important effect. Besides, it is also witnessed that in metal-porcelain restorations, structures in similar strengths are achieved with hollow type pontic designs as with solid type, if they are prepared in proper conditions.
