ONLAYS
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:
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.
