Can emax be used for posteriors?

For restorative dentists placing posterior crowns, e.max has been a trusted ceramic since Ivoclar introduced the system in 2005. The material handles premolar and first molar cases well, combining translucency close to natural dentin with a flexural strength that holds up under normal occlusal loading. The clinical rule most prosthodontists follow: if the patient grinds, shifts to full-contour zirconia on second molars. If the case is a premolar or aesthetic-zone posterior where patients care about natural appearance, e.max earns its place on the prescription form.

Preparation geometry matters more with lithium disilicate than with monolithic zirconia. Minimum 1.0 mm occlusal reduction is non-negotiable. Rounded internal line angles, no sharp margin transitions, and a butt or shoulder margin at 1.0-1.5 mm protect the restoration from fracture under load. When these parameters are met, the lab can press or mill a full-contour or cutback e.max crown that seats predictably and matches the adjacent shade without stacking porcelain on a weaker substructure.

At Dani Dental, posterior e.max cases ship in 5 business days from a confirmed digital scan. Every prescription includes the technician's direct contact, so if your prep geometry raises a question before milling begins, that call happens the same day the file lands, not after the case is already on the articulator.
