Unveiling the Composition of CEREC Crowns

When contemplating dental restoration, many patients question the materials behind the much-acclaimed CEREC crowns. Here, we break down what CEREC crowns are crafted from, especially considering their efficacy for molars.

The Pinnacle of CEREC: Its Choice of Materials

CEREC’s versatility in milling is pivotal to its widespread adoption. Among the multitude of options, two materials shine brightly – Emax and Zirconia. Zirconia takes the crown, literally, for being the most durable dental crown material. Conversely, Emax, sometimes referred to as ’empress to the max’ due to its all-porcelain lithium disilicate composition, is known for its remarkable bonding capability. This not only offers enhanced strength over traditional cement but also minimizes tooth reduction, given its superior bond with enamel.

Why Molars Prefer CEREC

Molars bear the brunt of our chewing forces, necessitating resilient restorations. So, are CEREC crowns up to the task?

• Durability: Crafted from ceramic, CEREC crowns demonstrate robustness, holding up to the vigorous demands of molars.
• Hygiene-friendly: Their design champions easy cleaning, crucial for molars susceptible to plaque.
• Efficiency: A highlight of CEREC crowns is their single-visit placement, sidelining the usual two appointments needed for traditional crowns.
• Value: Although CEREC crowns might have a steeper initial cost, the convenience and efficiency of a one-time appointment often offset this.
• Reduced Anxiety: For dental visit skeptics, CEREC’s single-session approach might be a relief.

Diving Deeper: CEREC’s Material Palette

CEREC crowns predominantly feature zirconia and Emax. Zirconia’s resilience against wear and tear is commendable, while Emax boasts aesthetic excellence, mirroring natural teeth’s appearance. Besides these, CEREC also employs materials that utilize composite and don’t need to be placed in an oven, reducing the amount of manufacturing time. These composite hybrids are good for temporary crowns and smaller restorations such as inlays and onlays.

Notable Mentions and Benefits of CEREC Crowns

Renowned institutions like the American Dental Association recognize the success of CEREC crowns. A significant study revealed a staggering 97% of these crowns remain intact five years post-placement. Though they command a premium over traditional crowns, their myriad advantages like natural aesthetics, longevity, and precision, thanks to CAD/CAM technology, make them a favorite.
