In modern dental restorations, zirconia has become one of the most popular materials thanks to its exceptional combination of mechanical strength, biocompatibility, and high aesthetic value. However, among the wide range of zirconia materials available today, determining which type is best suited for each clinical indication remains a key consideration for both laboratories and clinicians.
Ivoclar, a global leader in dental material technology, has introduced a comprehensive solution through its IPS e.max ZirCAD Prime and IPS e.max ZirCAD Prime Esthetic product lines. Both utilize Ivoclar’s exclusive Gradient Technology (GT), which allows a seamless transition between translucency and strength—creating restorations that are not only strong and stable but also exhibit natural optical depth and lifelike vitality.
But the question remains: When should we use ZirCAD Prime, and when is ZirCAD Prime Esthetic the better choice?
This article will help you understand the optimal clinical indications for each material and share essential practical tips to ensure consistent color and translucency throughout your zirconia restorations.
1. When to Use IPS e.max ZirCAD Prime
IPS e.max ZirCAD Prime is considered the most versatile and durable version within Ivoclar’s zirconia system.
Composed of 3Y zirconia in the cervical and body regions, this material provides excellent opacity for masking dark underlying tooth structures or Ti-base abutments—while still maintaining natural translucency in the incisal zone.
1.1. Superior Strength for Demanding Restorations
With a flexural strength of up to 1200 MPa, ZirCAD Prime can be safely used in high-stress applications such as:
- Long-span bridges (up to two pontics)
- Posterior bridges where high masticatory forces demand stability
- Cantilever or full-arch bridges on implants or temporary fixed restorations
This outstanding mechanical endurance makes ZirCAD Prime the go-to material for cases requiring maximum strength without compromising aesthetics, outperforming traditional opaque zirconia in both function and beauty.
1.2. The Ideal Choice for Single-Milling Systems
One of the reasons ZirCAD Prime is so practical for dental labs lies in its manufacturing flexibility.
For labs equipped with only one milling machine—meaning only one disc can be loaded at a time—ZirCAD Prime helps maximize productivity. With a single disc, technicians can mill both full-contour restorations and framework-based crowns for veneering, all in the same shade.
- This approach allows the lab to:
- Save time by avoiding frequent disc changes
- Reduce material waste
- Maintain color consistency across multiple restorations within the same clinical case
Imagine being able to let the milling machine run overnight with just one disc—and returning in the morning to find a set of perfectly milled restorations ready for sintering. That’s the operational advantage ZirCAD Prime brings.
2. When to Use IPS e.max ZirCAD Prime Esthetic
While ZirCAD Prime was developed to handle high-load, strength-demanding restorations, ZirCAD Prime Esthetic was designed to shine in the aesthetic zone—where light, translucency, and natural appearance are essential.
2.1. Refined Aesthetics for Anterior and Short-Span Restorations
ZirCAD Prime Esthetic utilizes 4Y zirconia in the body region combined with a highly translucent 5Y incisal layer, creating a seamless gradient from cervical to incisal—mimicking the optical behavior of natural enamel without the need for external porcelain layering.
This makes it especially suitable for:
- Single crowns in anterior and canine regions
- Short-span bridges (up to three units)
- Monolithic zirconia veneers
- High-aesthetic cases requiring good strength (approximately 850 MPa)
2.2. Time Efficiency – Reduced Veneering Steps
Thanks to its inherent translucency and smooth color gradient, ZirCAD Prime Esthetic significantly simplifies and accelerates fabrication:
- Reduces or eliminates the need for manual porcelain veneering
- Minimizes the risk of chipping or cracking of veneering layers
- Ensures color stability and uniformity across multiple restorations
This feature is particularly valuable for dental labs managing high production volumes while maintaining consistent, high-level aesthetics in every case.
