Dental crowns at One Harley Street Dental Practice

A crown is a ‘cap’ that fits over the entire surface of the tooth. The process of making a crown involves trimming the tooth down to the desired shape. Impressions of the tooth preparation are then taken. From the impressions, the laboratory can construct the crown.

Once fabricated, a crown is fitted over the tooth surface and bonded in place using special dental cements.The shape, size, colour and surface characteristics of a crown are closely matched to the surrounding teeth. They are fabricated by master ceramists to the highest possible standards and once fitted, provide a seamless and permanent restoration to a tooth.

Crowns can last a lifetime and are necessary for a number of reasons:

  • To restore heavily broken down teeth
  • To restore heavily filled teeth
  • To give form to broken or unusually shaped teeth
  • To treat discoloured teeth
  • To realign crowded or spaced teeth

There are many types of crown. Dr HAll limits his practice to All-Ceramic crowns and Gold-Ceramic crowns. Experience has shown that these constitute the optimum materials for such restorations.

Before and after treatment with crowns

All-Ceramic crowns are constructed in specially formulated ceramics and serve to replace the outer enamel layer of the tooth. In many cases, advanced computer technology is used to scan the dimensions of the tooth preparation from which the crowns are constructed.

This provides a perfectly fitting and sealed crown. These crowns are highly biocompatible and avoid the use of metals. They are bonded to the underlying tooth structure in such a fashion that they provide considerable added strength to the tooth preparation.

Ceramic-Gold crown utilises a high-gold alloy as substructure over which specially formulated ceramics are applied. The underlying gold matrix provides strength and a warm and bright core over which the layering of ceramics can be optimised to imitate the aesthetics of natural teeth. The high gold alloy is bio-compatible and non-allergenic.
