1. Characteristics of Airtron all-ceramic:

1. Airtron is a domestic brand and a professional manufacturer of precision ceramic materials. With a comprehensive product range and strong R&D capabilities, it is known as the leading domestic brand of zirconia. Compared to imported brands, it offers a lower price point and is more affordable.
2. It has excellent aesthetic properties. Due to its inherent yellow-white color, restorations created with it have no black lines along the gingival margins, resulting in a natural and beautiful appearance.
3. It has excellent biocompatibility and does not cause gingival inflammation or allergies.
4. It is highly corrosion-resistant, has poor thermal conductivity, and provides excellent protection for gum tissue.
5. Full zirconium crowns can be fabricated. Their strength reduces tooth wear and maximizes the preservation of natural tooth tissue. Since they are not made of metal, they are not affected by magnetic fields. Once the restoration is bonded into the mouth, it does not need to be removed for cranial X-rays, CT scans, or MRIs, saving significant effort.

Suitable for: Widely used in anterior and posterior restorations.
Product Strength: Airtron all-ceramic teeth also offer high strength, with a bending strength of approximately 1100 MPa and two strength options: 600-1100 MPa (in 50% increments).

2. Features of Weiland (German brand) porcelain:

A. Wiland ZENOSTAR utilizes patented ZENOSTAR all-ceramic material. This high transparency provides excellent flexural strength and aesthetics comparable to natural teeth.
B. Wiland ZENOSTAR is a more economical and biologically sound dental material. It replaces metal processing, especially non-precious metals, and offers the best value among similar dental materials.
C. Wiland ZENOSTAR restorations minimize wear on natural teeth and feature an open system.

Suitable for: Widely used in anterior and posterior tooth restorations, single or multiple teeth, including uneven, missing, yellowed, and fractured teeth. Denture restorations are also available. The product offers a natural, lifelike appearance and excellent biocompatibility.
Product Strength: With a flexural strength of approximately 1200-1300 MPa, Wiland’s chemical inertness and excellent biocompatibility make it particularly suitable for dental restorations. Wiland is the fourth largest dental brand in the world.

3. CERCON product features:

A. The German Zercon zirconia all-ceramic system was the first brand in the world to introduce CAD/CAM concepts into the design and processing of zirconia all-ceramic teeth, enabling the rapid production of beautiful and precise restorations.
B. The German Zercon is the only closed system on the market, meaning the zirconia block, CAD cutting machine, and ceramic powder are all integrated products, and production requires authorization from Dentsply. Other brands, aside from producing the blocks, do not have supporting products.
C. The German Zercon zirconium dioxide has a beautiful, natural color, comparable to natural teeth; it is highly transparent, thin, and lightweight; its color is lifelike and natural; it is durable in the dental environment; and it has excellent marginal adhesion, causing minimal damage to tooth tissue.

Suitable for: Most crowns and bridges, inlays, onlay bridges, and implant-mounted crowns/bridges.
Product Strength: German Zercon boasts a flexural strength of 1200 MPa, comparable to that of 3M Lava all-ceramic teeth in the United States. Experimental testing has shown that Zercon’s strength can reach 1400 MPa, second only to Lava, making it the world’s second-largest all-ceramic tooth brand.
