This Concept Map, created with IHMC CmapTools, has information related to: Assignment 7, intentional roughening such as sandblasting, grinding producing rough and irregular surface on the metal surface, significant to the initiation of chemical bond which is the most important mechanism, the overall bonding but only as a minor force, only as a minor force that is not as significant, enhances the metal-ceramic bond when ????, the porcelain itself rather than at the procelain- metal interface, difference between the coefficients of thermal expansion causes porcelain to compress toward the metal, air abrasions that appears to enhance wettability, BONDING MECHANISMS BETWEEN THE CERAMIC LAYER AND THE METAL SUBSTRUCTURE IN PFM RESTORATION Van der Waals Forces, attachment by interlocking the ceramic to metal coping through microabrasions, ceramic in a beneficial state of residual compressive stress at room temperature, gold alloy because it creates significantly stronger bond, air abrasions that appears to increase the surface area for chemical bonding, Mechanical bond/entrapment makes use of surface finishing, difference between the coefficients of thermal expansion of metal, gold alloy containing minute amounts of tin, beneficial state of residual compressive stress at room temperature due to the higher thermal expansion coefficient for metal, surface finishing that enhances the metal-ceramic bond, true adhesion since fracture/failure will occur
