Frequently Asked Questions
Can porcelain crowns crack?
In prosthodontic dentistry, one of the most seen complications is crown failure due to different reasons. With the advancements in technology, we can prevent this complication happen.
Nowadays, we have been using state-of-art milling systems and with these systems, we started to build nearly indestructible restorations. Since there is no layering of materials like before. The prosthodontic materials are build from one single block of material. Technically, we are milling/carving materials from one single block. This no-layering approach makes our porcelain crowns tough.
How do you produce PFM (traditional crowns)?
Initially, the dental lab technician makes a thin thimble of metal that fits perfectly over the tooth.
A layer of porcelain material is then fused over it in a high-heat oven, giving the crown both its tooth-like shape and colour.
Can porcelain crowns break?
Technically, everything breaks!
The real question is, which type of porcelain crown breaks easily?
There are different types of ceramic materials in the field of dentistry. We are currently using monolithic materials in the mouth, and they are not only durable materials but also look exactly like a natural tooth.
Let me show you how tough they are!
PFM vs Monolithic Zirconia
To be more clear, Porcelain Fused Metal (traditional porcelain crowns) has around 200MPA flexural strength while monolithic materials have 1000+MPA.
