Ceramill is a branded line of dental materials developed by Amann Girrbach, mainly used in digital dentistry. It is commonly used for making crowns, bridges, frameworks, and prosthetics using CAD/CAM (Computer-Aided Design and Manufacturing) systems.
Ceramill materials are typically made of:
Zirconia (Zirconium dioxide) – the most common, known for strength.
Lithium Disilicate – for better aesthetics.
Hybrid ceramics or PMMA – used for temporary crowns or implants.
When you say "1 – 3 units could be made," it means that from one disc or block of Ceramill material, you can create 1 to 3 dental prosthetics (like crowns or bridges) depending on the size.
High Strength and Durability
Especially in zirconia form, Ceramill materials are extremely tough and can withstand chewing pressure.
Biocompatibility
Safe for use in the human mouth; does not cause allergic reactions.
Excellent Aesthetics
Mimics the natural color and translucency of real teeth, especially in multilayered zirconia and lithium disilicate.
CAD/CAM Compatible
Easily milled and customized using digital machines for precise fittings.
Minimal Shrinkage
Controlled production ensures very little shrinkage during sintering, resulting in better accuracy.
Low Thermal Conductivity
Doesn’t transfer hot or cold easily, which protects the tooth's nerve.
Long-Lasting Results
Can last 10-15 years or more if cared for properly.
Less Tooth Reduction
Requires removing less natural tooth than metal-based crowns.
High Cost
More expensive than traditional metal or PFM (Porcelain-Fused-to-Metal) options.
Technique Sensitive
Requires proper CAD design, milling, and sintering. Errors in the process can lead to misfits.
Brittleness in Thin Sections
If made too thin or poorly supported, it can crack.
Wear on Opposing Teeth
Very hard zirconia may wear down the natural teeth it bites against if not polished correctly.
Not Suitable for Very Large Bridges
In some cases, longer-span bridges may not be ideal with certain ceramic types.
For precision – With CAD/CAM support, it offers exact fittings.
For aesthetics – Looks more natural than metal-based restorations.
For long-term durability – Especially good for molars and bridges.
For comfort and safety – Being metal-free, it suits patients with allergies.
