ANSWERS

What is the best anterior crown material?

For anterior crowns, lithium disilicate (e.max) leads on esthetics and bond strength at 400 MPa flexural strength, making it the default choice for centrals, laterals, and canines where shade match matters most. Layered zirconia works for patients with heavy occlusion or limited reduction.

THE SHORT ANSWER

THE FULL PICTURE

Why it works this way

The default: lithium disilicate for most anterior cases

For restorative dentists sending anterior crown cases, lithium disilicate (marketed as IPS e.max by Ivoclar) is the working default. The material runs around 400 MPa flexural strength, etches and bonds predictably with resin cement, and takes stain and glaze layering that reproduces incisal translucency on centrals and laterals. Ivoclar's clinical data on e.max, tracked since the material's 2005 launch, shows survival rates above 95% at 10 years for single-unit anterior crowns when bonded adhesively.

Is zirconia strong enough to replace e.max for anterior crowns?

Strength was never the question for anteriors. Lithium disilicate at 400 MPa is more than adequate for incisal load on centrals and laterals; the limit is esthetics, not fracture. Multilayer zirconia disks have improved translucency since 2020 and now compete on single-unit anteriors for patients with heavy occlusion or thin prep clearance. For a high-smile-line central next to a virgin tooth, layered e.max or feldspathic still produces a better incisal halo than monolithic zirconia.

What information should a dentist send with an anterior crown case?

Full-arch digital scan or polyvinyl impression, opposing arch, bite registration, stump shade (the prepped tooth color, not the target shade), target shade with VITA or 3D-Master reference, and a high-resolution photo of the adjacent dentition in natural light. For multi-unit anterior cases, a smile photo and incisal-edge position notes help the ceramist plan the layering. Dani Dental's case form captures these fields by default, and the assigned technician calls the office if anything is missing before milling starts.

How long does an anterior crown take to fabricate?

Standard turnaround for a single anterior lithium disilicate crown runs 5-7 business days from case receipt to ship, assuming the case arrives complete (scan, bite, shade, photo). Layered feldspathic on a refractory die runs 8-10 business days because the build-up and firing cycles are manual. Rush cases ship in 3-4 days when the practice flags the slip. Multi-unit anterior cases requiring try-in stages run 2-3 weeks depending on stage count.
