Ceramic restorations may be used in some situations to restore teeth where white fillings (composite resins) are not suitable. Ceramic restorations include inlays, onlays and crowns.
Such situations may be:
- If there is heavy loading on a tooth such as on a molar
- If there is a large area of the tooth to restore. This may be a result of the tooth being badly broken down – either a cusp has broken off, or there are large old fillings or a large portion of decay
- If you grind and/or clench your teeth
An Inlay or Onlay is a similar shape to a filling and fits into or over a tooth like a puzzle piece fits into a jigsaw puzzle. It may provide a stronger alternative than a composite filling to restore a tooth.
A Crown, also known as a “cap” is a restoration which completely caps or encircles a tooth. The original tooth is filed down to make room for the crown. Crowns are often needed when a tooth has been weakened by a large cavity or a crack.
BCD crowns and inlays are generally made from porcelain over a zirconia base and are custom fabricated in a Sydney laboratory.
