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.

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.
