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.
