DENTAL CROWN

The anatomy of a tooth can be divided into two basic parts – the root and the crown. In a person with healthy gums and bone, the root of the tooth is covered by the gums and bone. The part of the tooth that is visible in the mouth, above the gum line on lower teeth and below the gum line on upper teeth, is called the clinical crown is referred to as a dental crown or cap.

Crown Preparation

This is the design of the tooth after it has been shaved down to allow room for a crown. The preparation design depends on the material that the crown will be made from, previous fillings, fractures, and root canals therapy performed on the tooth while trying to maintain enough tooth structure for the crown to adhere onto.

Different Types of Crowns

Crowns can be made out of a gold alloy, some other metal alloy, stainless steel, all-porcelain/all-ceramic, composite resin, zirconia on the inside. There are advantages and disadvantages to all of the types of dental crowns. Stainless steel crowns are preformed crowns used to cover baby teeth for children. Gold dental crowns have traditionally been the most durable and require less of the tooth to be removed or shaved down. The primary advantage of porcelain crowns is their esthetics, while newer types of ceramic crowns have become increasingly more durable.
