ONLAY RESTORATION
 
  • Dental Code: D2644 – Onlay Restoration
  • This procedure is performed when dental fillings are not enough to solve the problem such as in cuspal fracture. Capping a damaged tooth unnecessarily with a dental crown removes more tooth structure than needed. But a large dental filling can weaken the remaining structure of the tooth, causing the tooth to break, crack or eventually need a root canal.
  • It is an indirect restoration which incorporates a cusp or cusp by covering or onlaying the missing cusp
  • An onlay is sometimes also referred to as a partial crown.  It is made by a professional dental laboratory and is permanently cemented onto the tooth by your dentist.
 
  • Reasons for onlay restorations:
    • Broken or fractured teeth.
    • Cosmetic enhancement.
    • Decayed teeth.
    • Fractured fillings.
    • Large fillings.
