The Adhesion Of Dental Porcelain To Various Metals

The adhesion of porcelain to metal in dentistry has been studied using different techniques. The highest stress at bond failure was reported in most studies which may not represent the real bonding characteristics correctly. This study aimed to evaluate bonding characteristics in porcelain fused to metal system by determining the strain energy release rate at the interface of porcelain and metals used in dentistry. Porcelain-veneered metal plates cast from gold, plalladium, and nickel-chromium alloys were made to dimensions of 25mm x 8mm x 3mm with equal and uniformed thickness of eacy layer.
