ALL CERAMICS
ZIRCONIA
Zirconia
Advancements in dental research have introduced newer formulations that offer distinct advantages over traditional techniques. One material that has emerged as a top contender is zirconia, combining exceptional strength with lifelike aesthetics.
Zirconia crowns provide patients with an extremely durable and long-lasting restoration, boasting improved aesthetics compared to porcelain-fused-to-metal (PFM) crowns. With different chemical formulations available, zirconia can be used in various applications that demand both strength and superior aesthetics.
Zirconia is a biocompatible material widely used in non-metallic medical joint replacements and all-ceramic dental implants, ensuring compatibility with the body.
No Metals Required
Unlike PFM crowns, zirconia does not require a metal substructure for strength and stability. This eliminates any metal visibility or unsightly margins, benefiting patients who are sensitive or allergic to metal.
With exceptional resistance to wear, zirconia is highly resistant to fracture or cracking. Its superior fracture resistance surpasses other dental materials. It is capable of withstanding bruxism and para-functional habits.
Reduced Chair-time and Adjustments
Zirconia crowns can be milled with exact specifications using CAD/CAM technology, resulting in a precise fit that minimises chair time and adjustments. Resin ionomer cements are ideal for retaining these restorations to the natural tooth structure.
When it comes to aesthetics, Zirconia’s translucent nature allows it to blend seamlessly with surrounding teeth, and it is available in a wide range of shades for accurate colour matching.
Zirconia crowns have revolutionised dental restorations, offering a winning combination of strength and aesthetics. Understanding the advantages and potential drawbacks empowers clinicians to make informed decisions and provide patients with long-lasting, visually appealing solutions.
Porcelain Fused to Zirconia (PFZ)
At Yen Dental Laboratory, we proudly offer PFZ crowns that represent a remarkable fusion of strength and aesthetics. Porcelain Fused to Zirconia (PFZ) restorations provide the ideal alternative to traditional PFM crowns.
PFZ crowns are created by layering porcelain over a zirconia base. This white zirconia substructure is precisely milled using CAD/CAM technology, resulting in a restoration that harmoniously matches the final desired look. With their ability to allow more light transmission, PFZ crowns are particularly suitable for anterior teeth, delivering exceptional aesthetic outcomes.
Strength of Zirconia + Beauty of Porcelain
Combining the strength of zirconia with the beauty of aesthetic porcelain, PFZ crowns offer a superior solution that overcomes the aesthetic challenges often associated with PFM restorations, such as discolouration or unsightly dark lines near the gum-line.
The natural translucency of zirconia brings warmth and lifelike coloration to these crowns. The combination of a zirconia substructure and layered porcelain results in an incredibly strong prosthetic (1000 Mpa and higher) with unparalleled translucency, suitable for both anterior and posterior restorations.
At Yen Dental Laboratory, we prioritize your success by equipping you with the necessary information to navigate the world of all-ceramic restorations. By establishing a strong partnership built on trust and effective communication with our laboratory, and by staying informed about the latest materials, you can provide your patients with the best possible outcomes.

Minimise Allergic Reactions
Zirconia used in PFZ restorations is biocompatible, ensuring compatibility with the human body and minimising the risk of allergic reactions. Meanwhile, the PFZ restorations can be easily re-polished to a high gloss after grinding, maintaining their aesthetic appeal for an extended period.
The bond between porcelain and zirconia is also stronger compared to other materials like gold, minimising the risk of fracture and enhancing the longevity of the restoration.
Furthermore, PFZ crowns offer an advantage over metal-based crowns by reducing the potential for oral galvanism or electrogalvanism. With multiple metal restorations in the mouth, the interaction between different electric potentials can create a minor electric current through saliva. PFZ crowns, being metal-free, mitigate this concern, ensuring optimal oral health and comfort for patients.
Multilayered Monolithic Zirconia
The Multilayered Monolithic Zirconia represents an innovative dental solution that combines cutting-edge technology with remarkable aesthetics. With its 100% metal-free composition, Multilayered Zirconia offers a host of benefits that not only enhance the natural beauty of your patient’s smile but also prioritise their oral health.
One of the standout features of Zirconia Layered is its ability to prevent gingival darkening and eliminate the risk of exposing metallic margins in case of gum recession.
Multilayered Monolithic Zirconia further boasts exceptional strength, making it an ideal choice for multi-unit bridges where other materials like IPS e.max may not be suitable. Through the precise layering of porcelain on the facials and buccal surfaces, even long-span bridges can achieve astonishing aesthetic results.
Game-Changing Attributes
What makes Multilayered Monolithic Zirconia a game-changer in the field of restorative dentistry? Here are some of its outstanding attributes:
High Flexural Strength
Multilayered Monolithic Zirconia exhibits impressive resistance to fractures and cracks, ensuring long-term reliability and durability.
High Biocompatibility
It is highly compatible with the human body, promoting a healthy tissue response and minimising the risk of adverse reactions.
Excellent Aesthetics
Multilayered Monolithic Zirconia possesses a semi-transparent quality with high opacity, allowing it to effectively mask underlying tooth discolouration, metal cores, and implant abutments. The result is a naturally beautiful smile that exudes confidence.
Outstanding Marginal Fit
Yen Dental Laboratory’s Multilayered Monolithic Zirconia ensures a precise and snug fit, reducing chair time and enhancing overall patient comfort.
Cementable
This versatile material can be easily cemented using standard cementation materials and techniques, simplifying the treatment process for dental professionals.

This metal-free solution is hypoallergenic, reducing the risk of allergic reactions and ensuring patient comfort.
Some Contraindications to Take Note
For all its benefits, it’s important to note that Multilayered Monolithic Zirconia is contraindicated for feather-edge feather-edge applications. Additionally, when preparing for the placement of Zirconia Layered restorations, Yen Dental Laboratory recommends an axial reduction of 1.0-1.5mm for anterior and posterior crowns, along with an occlusal reduction of 1.5-2.0mm.
To cement Zirconia Layered restorations, standard cementation materials and techniques can be employed, ensuring a secure and long-lasting bond.
Multilayered Monolithic Zirconia (Extra Translucency)
The growing popularity of full-ceramic zirconia in the dental industry has brought forth significant advancements. However, challenges persist in achieving the desired shading effects during the milling process. Dental laboratories face hurdles such as uneven dyeing, lack of apparent transition, and occasional mistakes during the intricate shading steps.
Extra Translucency Multilayered Monolithic Zirconia represents a significant improvement over previous zirconia crowns. This ground breaking solution empowers dental labs to consistently achieve outstanding shading results on their crowns and bridges, with an enamel-like translucency that perfectly replicates natural teeth.
