An onlay is sometimes also referred to as a partial crown. Porcelain onlays are popular because they resemble your natural tooth.
Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Onlays can be an alternative to crowns (caps) because less tooth structure is removed in the preparation of onlays. Onlays are essentially identical to inlays with the exception these can partially cover part of the chewing area as well.
An onlay restoration is a custom made filling made of composite material, gold, or tooth-colored porcelain. These are made by a professional dental laboratory and is permanently cemented onto the tooth by your dentist.
As with most dental restorations, onlays are not always permanent and may someday require replacement. They are highly durable and with good oral hygiene and regular office visits will last many years, giving you a beautiful long lasting smile.
Reasons for onlay restorations:
- Cosmetic enhancement.
- Large fillings.
- Decayed teeth.
- Fractured fillings.
- Broken or fractured teeth.
An onlay is prepared an installed, in two appointments, following the same procedure as an inlay.
While you will receive care instruction at the conclusion of your treatment, normal good home oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new porcelain onlay.
