Ceramic Reconstruction-An Alternative to a crown
Have you been told you need a crown?
When older fillings break down, many dentists recommend crowns for stronger
protection of teeth.
Crowns traditionally require a mould made of synthetic rubber that sets
inside your mouth, and then a temporary plastic crown covers your tooth
for a few weeks. Crowns are traditionally made out of gold covered by
porcelain, and often require a foundation, which adds to the overall cost
of having a crown.
All this treatment takes about three weeks.
But now there's a better way, with a new technique called single-visit
ceramic reconstructions, or CEREC® for short.
This technology was first developed in Switzerland in 1987, and I have
been using it since 1999.
So what's so different about CEREC®?
The main advantage for many people will be timethe CAD/CAM CEREC®
system will reconstruct your tooth in less than two hours from start to
finish.
Another bonus is that no impression is required. The system relies on
a sophisticated infra-red scanning camera that takes a snapshot inside
your mouth and creates a virtual tooth inside a specialised computer,
so you never have a mouth full of rubber.
Your new tooth is then milled from a dental bio-ceramic produced especially
for CEREC® reconstructions.
It's the dental porcelain which CEREC uses which is the real secret of
the system: unlike traditional porcelain or gold, it expands and contracts
with your living tooth structure. This means that hot drinks or ice-cream
don't create temperature shocks for the tooth like traditional materials
such as silver or plastic. This ability to mimic nature also means that
the ceramic feels just like your own tooth. Because it is porcelain, with
no gold metal, it also looks like your own toothsomething many patients
find important today.
This one-visit treatment is available for most dental reconstructions
where crowns used to be prescribed. I can also create lifelike and durable
porcelain veneers for worn front teeth. With the benefits of CEREC®,
I only prescribe tooth coloured crowns, and almost all are performed in
a single dental visit.
