A crown falls into the category of dental restoration and involves capping a tooth or dental implant. They are often needed when a significant cavity threatens the structural integrity of a tooth. Meanwhile, a bridge replaces a missing tooth by joining an artificial tooth permanently to adjacent teeth or a dental implant.
Types of Crowns
Crowns are usually bonded to the tooth with a type of dental cement. There are three basic types of crowns: 1. Porcelain outer surface with a metal base crown. 2. Pure porcelain or composite crown. 3. All metal crown, which is usually gold. They all differ in durability, strength, appearance and cost.
Crown lengthening is a surgical procedure that recontours the gum tissue and often the underlying bone of a tooth. Crown lengthening is often needed for a tooth to be fitted with a crown. It provides necessary space between the supporting bone and crown, which prevents the new crown from damaging bone and gum tissue.
Types of Bridges
The materials used for the bridges include porcelain fused to metal, or sometimes only porcelain. Usually, the neighbouring teeth are reduced in size to accommodate the material used to restore the missing tooth. The amount and type of reduction done depends on the material used.
