Inlays & Onlays | Ho-Ho-Kus NJ
When more than half of the tooth’s biting surface is damaged a dentist will often use inlays/onlays.
What are inlays/onlays?
Inlays/onlays can be made of porcelain, gold, or a composite resin. These pieces are bonded to the damaged area of the tooth. An inlay (which is similar to a filling) is used inside the cusp tips of the tooth. An onlay is a more substantial reconstruction (similar to the inlay), but extending out over one or more of the cusps of the tooth.
Traditionally, gold has been the material of choice for inlays/onlays. In recent years, however, porcelain has become increasingly popular due to its strength and color which matches the natural color of your teeth.
How are they applied?
Inlays and onlays require two appointments to complete the procedure. During the first visit, the filling being replaced or the damaged or decaying area of the tooth is removed and the tooth is prepared for the inlay or onlay. To ensure proper fit and bite, an impression of the tooth is made by Dr. Klotz and sent to the lab for fabrication. Dr. Klotz will then apply a temporary sealant on the tooth and a subsequent appointment will be scheduled.
At the second appointment, the temporary sealant is removed. Dr. Klotz will then make sure that the inlay or onlay fits correctly. If the fit is satisfactory, the inlay/onlay will be bonded to the tooth with a strong resin and polished for a smooth finish.
Traditional fillings can reduce the strength of a natural tooth by up to 50% . As an alternative, inlays/onlays that are bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75%. As a result, they can last a very long time. In some cases, where the damage to the tooth is not extensive enough to merit an entire crown, onlays can provide a very good alternative.
