When a tooth
has been moderately to extensively destroyed by decay, previous
drilling, or fracture but there is still sufficient enamel
remaining, one innovative way it can be restored is with
a porcelain inlay or onlay. An inlay is a restoration in
which a portion of occlusal (biting) surface is replaced
with porcelain. An onlay will restore a larger portion of
the biting surface of the tooth. These are considered very
conservative restorations. The porcelain allows an excellent
esthetic result. It is attached to the tooth using a bonding
procedure, allowing it to become very strong. It can be
used with wonderful results in small, medium, and even large
restorations lasting more than 12 years, relatively trouble-free.
A dental
laboratory is involved in the construction of the restoration.
There is a 2- to 3-week delay while the inlay or onlay is
being made, so the tooth must have a temporary restoration
in place during that time.
 They
have some disadvantages. They are moderately expensive to
very expensive to make and place. They take two appointments
to complete. They must be adjusted and polished well or
they can cause wear of the opposing enamel, similar to a
porcelain fused to metal crown. Of course, we make sure
they are adjusted and polished well to begin with. Porcelain
biting surfaces can cause more rapid wear of opposing natural
teeth, especially in the posterior areas where a metal biting
surface may be advised.Advantages
include the excellent esthetics, high strength, predicted
longevity, and conservative preparation, that is, less drilling
than a crown. If the porcelain does chip, it can be repaired.
However, you should not chew ice cubes, “jaw breakers,”
or any other hard candy with these or any other type of
restoration.
For those
who want the strongest, longest-lasting, conservative restoration
that very closely matches a tooth, porcelain is possibly
the best choice. Once it is finished, the tooth, if cared
for properly, should not have to be restored again for years.
It does allow the conservation of most of the natural tooth.
 Resin
Resin inlays and onlays are used in the same areas as the
porcelain inlays and onlays. They are very natural in appearance
and, like porcelain, are bonded into place. They are considered
an extremely conservative restoration. Two appointments,
approximately 2 weeks apart, are required to fabricate the
resin inlay/onlay. The tooth will be protected with a temporary
filling while the final restoration is being made. The wear
of the resin is similar to that of enamel. So unlike porcelain,
it will not have a tendency to wear the opposing natural
tooth structure. The
resin may be considered slightly “weaker” than
porcelain. However, porcelain is more brittle and more difficult
to repair. The difference in strengths is not significant.
The resin is more forgiving and is more easily finished
or repaired and resin is easier to work on.With
both types of materials, porcelain or resin, you can develop
decay on unrestored surfaces, so excellent oral self-care
is required. Neither material is advised for patients who
have a bruxing (grinding) or clenching habit unless a protective
mouthguard is constructed for you.
Unless you
have a preference, we will select the most appropriate material
for your dental needs. Cost of each is comparable. Both
types are excellent choices and are considered highly conservative
in the amount of drilling needed.
