General preparation guidelines for Zirlux zirconia include the following:  \nPreparation should follow the anatomy of the tooth, providing at least the minimum thickness required for the respective restoration (see Minimum Zirconia Thickness to the right) . Axial and occlusal reduction of 1. 0mm is considered ideal for full-contour zirconia restorations.  \nA definitive finish line (i. e. , shoulder with rounded internal line angles or chamfer margin) is recommended. Featheredge preparations are acceptable for Zirlux restorations.  \nAll sharp edges and line angles should be rounded.  \nAvoid undercuts, 90-degree shoulders, and gutter preparations.  \nMinimum Zirconia Thickness—Bridges  \nAnterior  \nAxial  \nIncisal/Occlusal Connector Dimensions  \nPosterior  \nAxial  \nIncisal/Occlusal  \nConnector Dimensions  \n3-Unit  \n0. 5mm  \n0. 5mm 7mm2  \n3-Unit  \n0. 5mm  \n0. 5mm 9mm2  \n4+ units  \n0. 7mm  \n0. 7mm 9mm2  \n4+ units  \n0. 7mm 1.0mm  \n12mm2  \nCantilever with 1 pontic  \n0. 7mm  \n1.0mm 12mm2  \nCantilever with 1 pontic  \n0. 7mm  \n1.0mm 12mm2  \nMinimum Zirconia Thickness—Crowns  \nAnterior/Posterior  \nAxial  \nIncisal/Occlusal  \nCrowns  \n0.5mm  \n0.5mm  \nIdeal Chamfer Margins—Posterior  \nOcclusal reduction of 1. 0mm ideal; 0. 5mm is the minimum.  \nRounded internal line angles.  \nTaper between 4 and 8 degrees.
