This Concept Map, created with IHMC CmapTools, has information related to: Assignment 7_Cherie's Version, ceramic in a beneficial state of residual compressive stress at room temperature, Compressive Forces caused by difference between the coefficients of thermal expansion, Van der Waals Forces Contribute to the overall bonding, observed increase in bond strength considered as true adhesion, BONDING MECHANISMS BETWEEN THE CERAMIC LAYER AND THE METAL SUBSTRUCTURE IN PFM RESTORATION Van der Waals Forces, true adhesion prefers to use gold alloy, air abrasions that appears to increase the surface area for chemical bonding, Mechanical bond/entrapment makes use of surface finishing, intentional roughening such as sandblasting, true adhesion since fracture/failure will occur, grinding producing rough and irregular surface on the metal surface, difference between the coefficients of thermal expansion of ceramic, bonding agent such as platinum spheres (3 to 6 micrometers in diameter), sandblasting producing rough and irregular surface on the metal surface, attachment by interlocking the ceramic to metal coping through microabrasions, microabrasions in the surface of metal coping, Chemical bonding indicated by observed increase in bond strength, Chemical bonding indicated by oxide layer formation on the metal, gold alloy because it creates significantly stronger bond, produced by finishing the metal with non contaminating stones
