Porcelain Onlays

An onlay is a custom made restoration made of  gold, or tooth-colored porcelain.  Porcelain onlays are popular because they resemble your natural tooth.  An onlay is sometimes also referred to as a partial crown. Whenever a cusp is broken or the filling gets to be too large an onlay is recommended.  We have the technology available to complete an onlay in one visit in our office. It takes a little over an hour and no impression is needed. We have a CEREC machine in our office and have been using this technology for more that 6 years.

Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma.  Onlays are an ideal alternative to crowns (caps) because less tooth structure is removed in the preparation of onlays.  Onlays are essentially identical to inlays with the exception that one or more of the chewing cusps have also been affected and need to be included in the restoration.

As with most dental restorations, onlays are not always permanent and may someday require replacement. (rarely need to replace, they are made of porcelain so they can break, but for the most part are extremely durable)

Reasons for onlay restorations:

  • Broken or fractured teeth.
  • Cosmetic enhancement.
  • Decayed teeth.
  • Fractured fillings.
  • Large fillings.

What does getting an onlay involve?

An onlay procedure usually requires one appointments.  No temporaries here! While the tooth is numb, the dentist will remove any decay and/or old filling materials.  The space will then be   prepared, shaping the surface to properly fit an onlay restoration. We scan the tooth, make the restoration, then bond it into place about 20 minutes later. No messy impressions with an onlay.

A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.

You will receive care instruction at the conclusion of your treatment.  Good oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new onlay.
