An onlay restoration is a custom made filling made of composite material, 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. 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 where cuspal coverage is required. 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. They are highly durable and will last many years, giving you a beautiful long lasting smile.
