This Concept Map, created with IHMC CmapTools, has information related to: Metal Coping Design Final, axial wall in order to allow light trnansmission into the tooth rooth adjacent to the margin, Maxillary Posterior Teeth Advantage for recommended design more resistance to fracture, Lingual surface recommended size 3.0 mm, higher yield strength may be as thin as 0.2 mm, add correction procelain to the margin after full contour buildup of the crown was then condensed through compression, Maxillary Posterior Teeth design rounded ledge of metal under the facial cusp, Conventional Metal collar Heavy Chamfer, porcelain on facial surface extends halfway down palatal incline, All-porcelain facial margin Advantages improvement in periodontal health, An outer junction of porcelain to metal that is at a right angle (90 degrees) to avoid subsequent fracture of the porcelain, Extent of the area to be veneered for porcelain Metal Collar Width facial surface, Features to consider when designing the metal coping for a PFM restoration Thickness of the metal underlying and adjoining the porcelain, Thickness of the metal underlying and adjoining the porcelain may vary, all-porcelain shoulder through the use of direct-lift techniques, contoured so that the overlying veneer will be subject to compressive, Design of the Facial Margin Fabrication, rounded ledge of metal under the facial cusp to support porcelain, Fabrication involves either refractory die supports the porcelain margin during firing, low-fusing porcelains to cover metal coping, Porcelain-Metal Junction Line is Placed 1.0 mm from occlusal contacts at the position of maximal intercuspation
