What are Onlay Restorations?

An onlay restoration is a custom-made filling made of composite material, gold, or tooth-coloured porcelain. Porcelain onlays are popular because they resemble your natural tooth. An onlay is sometimes also referred to as a partial crown. Porcelain onlays are made by a professional dental laboratory and is permanently cemented onto the tooth by your dentist.

Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Onlays are ideal alternatives 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.

They are highly durable and will last many years, giving you a beautiful long lasting smile. However, as with most dental restorations, onlays are not always permanent and may someday require replacement.

Reasons for onlay restorations

An onlay restoration may be indicated for:

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

What is the Procedure for an Onlay Restoration?

An onlay procedure usually requires two appointments.

Your first appointment will include taking several highly accurate impressions (moulds) that will be used to create your custom onlay and a temporary restoration. While the tooth is numb, the dentist will remove any decay and/or old filling materials. Space will then be thoroughly cleaned and carefully prepared, shaping the surface to properly fit an onlay restoration. A temporary filling will be applied to protect the tooth while your onlay is made by at the dental laboratory.

At your second appointment, your new onlay will be carefully and precisely cemented into place. A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.

You will receive care instructions 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.
