Dental Crown

A dental crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. Crowns are bonded to the tooth using a dental cement. A crown can make your tooth stronger & improve its appearance.

Reasons to restore with a crown:

- Endodontically treated teeth

- Esthetics

- Implants

Types of crowns :

1. All ceramic crowns: Porcelain based filling material recommended for restoring front teeth due to color blending with the natural teeth. Highly resistant to wear.

2. Porcelain fused metal: Underlying metal fusedwith porcelain provides stability & strength to the crown. They have very high rate of success in the long run.

3. Zirconia or milled crown: are the most esthetic crowns. Zirconium crowns are more robust than porcelain crowns. They last longer too.

Its many advantages include:

- Less tooth removal.

- Translucent enough to be similar to natural teeth.

- can withstand wear & tear.

- No metal fuse.

4. Monolithic crown: means it is fabricated in a full contour from a single block of material. Monolithic press is stronger than a layered one.

Monolithic material offers greater flexural strength & no chipping of the porcelain veneer.

5. All metal crown: Metals used in crowns include gold alloy , other alloys (for eg. Palladium), or a base metal alloy (nickel,chromium). Compared with other crowns less tooth structure needs to be removed. Metal crowns rarely chip or break. These crowns are a good choice for out of sight molars.
