 Your
teeth play an important role in your overall health as well as
your appearance. So, naturally, you want to do everything you
can to keep them healthy and looking good.
Sometimes, however, tooth decay advances to a point where a
tooth is too weak to survive with just a direct restoration or
filling. Instead, your dentist may recommend an indirect
restoration also known as a crown or bridge . In these cases,
the decayed area is removed and the restoration is fitted over
the original tooth.
This is a step that can help preserve the health and appearance
of your smile.
The evolution of restorations.
Traditionally, crowns and bridges were made of metal, because it
is strong and relatively inexpensive.
Then came porcelain fused to metal restorations , which came
closer to the look of real teeth and provided strength,
durability and fit.
But it is difficult to achieve the translucency of your natural
teeth with a restoration that has a metal framework. Light does
not pass through the metal restoration like it does through your
own teeth, leaving a dull, lifeless appearance.
In addition, over time, the metal framework can leave a dark
ridge where the gums recede.
Today, there’s a solution as beautiful as
nature itself: 3M™ ESPE™
Lava™ Zirconia restorations.
Lava Zirconia offers the benefits of porcelain fused to metal
strength and longevity.
Just as important, Lava Zirconia restorations can be matched
precisely to the color of your own teeth and provide the natural
translucency that metal-based restorations can’t
 How Lava
Zirconia restorations are
made.
To make a Lava TM crown or bridge, your dentist will take an
impression of your mouth, and send it to laboratory. There, a
technician, using computer-aided design technology, will use the
impression to create a model of your mouth. After creating a
precise framework for your restoration, a dental technician will
build up layers of ceramic onto the framework so that the final
restoration will match your natural teeth. The completed
restoration will then be delivered to your dentist who will fit
it for you. |
