An onlay restoration is a custom made filling made of
composite material, 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. 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 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.
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 two appointments. Your
first appointment will include taking several highly
accurate impressions (molds) 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. The 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 a 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 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.
