A crown is a type of dental restoration that fully cups over that portion of a tooth or dental implant that lies at and above the gum line. Dental crowns – often referred to as “dental cap” “tooth cap” or “porcelain jackets” – are necessary when the tooth is decayed to an extent that it cannot be filled or partly restored by an inlay or onlay, so it has to be filed under local anaesthesia and then covered with a crown.

The perfect outcome is reached in a very short lapse of time due to in almost all steps computerized workflow.
