All ceramic crowns are a popular choice of restoration, particularly on teeth that are highly visible, because they look so natural and lifelike. Made from 100% ceramic they mimic the natural luminous glossy look of a natural tooth. Also typically, the thicker the ceramic and more translucent the porcelain, the closer it matches the light handling characteristics of a natural tooth.

Indications

  • Ceramic has a natural translucency which mimics that of a natural tooth
  • Ceramic can be easily and precisely shade matched to blend in with the patient’s existing teeth

Contraindications

  • Should not be used for patients with a deep overbite, a super-erupted opposing tooth, or short clinical crown
  • Because ceramic is easily broken and can be abrasive, it is not a suitable choice for patients with bruxism or other para-functional habits
  • Ceramic restorations must be kept dry when cemented in place if the outcome is to be successful

Advantages:

  • The natural appearance of all ceramic restorations makes them a popular choice
  • All ceramic restorations are more durable than most other direct restorative materials
  • They’re bio-compatible making them a good alternative for patients suffering from metal allergies
  • Since all ceramic restorations are fabricated indirectly, it allows for a more accurate shape and fit, when compared to directly placed restorations

Disadvantages:

  • It can take at least two appointments to complete since all ceramic restorations are fabricated indirectly. As a result additional lab fees can make this type of restoration more expensive than other direct restorations
  • Because ceramic is brittle, an adequate thickness of ceramic needs to be used to prevent fracturing
  • In most cases fractures are not normally able to be repaired
  • Ceramics can potentially cause wear to opposing teeth and/or restorations in certain circumstances
