Crowns & Bridges
They are used to replace Damaged or Missing teeth.
Why is a crown needed?
- To protect a tooth weekend by decay from breaking
- To protect a root canal treated tooth
- To restore a severely worn or a grossly broken tooth
- To cover and support a tooth with a large filling, when there isn’t a lot of tooth left
- To cover a discolored or misshaped tooth
- To make smile makeovers.
When is bridge needed?
It is a fixed prosthesis used to replace single or multiple missing teeth in mouth, it fills the gaps created by missing teeth & thereby restores mouth to healthy state.
A bridge is made by reducing natural tooth on either side of missing tooth using them as support.
How do Bridges Work?
Types of crowns
Different Types Of Crowns And Bridges:
- Vitallium Crowns and Bridges (Full metal) :
Base metal alloys contain non-noble metals which provide great strength to the crown and tooth and provide high resistance to corrosion. When preparing the tooth using base metal alloys, the dentist or prosthodontist would remove the least amount of healthy tooth structure. This material is resistant to wear and gentle to opposing teeth.
- Porcelain Fused to Metal :
Porcelain fused to metal is connected to the outside of a metal structure to provide strength to the teeth as well as provide a good seal to prevent leakage and decrease recurrent dental decay. When porcelain is fused to metal, it provides a stronger restoration than porcelain alone. The dentist or prosthodontist will remove a moderate amount of tooth structure, but it is very durable and strong.
- All Ceramic :
All ceramic crowns are a porcelain-based filling material and recommended for restoring front teeth due to color blending with the natural teeth. The dentist or prosthodontist may need to remove more tooth structure to attach the porcelain to the tooth; however, the material may be brittle under heavy biting and can be highly resistant to wear.
- Precious Metal (Gold) :
Gold alloys are comprised of gold, copper and other metals and provide a strong material to adhere to the tooth structure. Gold alloy is resistant to wear and fracture and does not wear away the teeth it comes in contact with. This material is highly biocompatible with the gum tissue.
