In case of such teeth, where the existing tooth tissue doesn’t enables the preparing of a permanent filling, the fixing of a crown is advisable. With the help of a crown the anatomical form of the tooth can be restored, hereby we can make corrections from the aesthetic and functional aspect, as well. By preparing the abutment the dentist removes the tooth tissue in a certain thickness from the surface of the tooth , that ‘s where the crown is placed, like a thimble. This consits of two parts, a cap and a ceramic cover. The ceramic part covers the metal completely , therefore it is really aesthetic.
