When more than half of the tooth’s biting surface is damaged, a dentist will often use an inlay or onlay.
WHAT ARE DENTAL INLAYS AND ONLAYS?
Inlays and onlays can be made of porcelain, gold, or composite resin. These pieces are bonded to the damaged area of the tooth. An inlay, which is similar to a dental 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 and onlays. In recent years, however, porcelain has become increasingly popular due to its strength and color, which can potentially match the natural color of your teeth.
HOW ARE INLAYS AND ONLAYS APPLIED?
Inlays and onlays used to require two appointments to complete the procedure, however, with our E4D Dentist system, most inlays and onlays can be completed in one simple visit to our office. During the first part of the 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, either an impression of the tooth is made, or digital photographic scans are taken of the tooth, and then using our software, Dr. Montoya designs and mills the restoration to be fit perfectly to your tooth.
Once it is determined that the inlay or onlay fits correctly, Dr. Montoya will bond it to the tooth with strong resin cement and then polish it to a smooth finish.
CONSIDERATIONS FOR INLAYS AND ONLAYS
Traditional fillings can reduce the strength of a natural tooth by up to 50 percent. As an alternative, inlays and onlays, which are bonded directly onto the tooth using special high-strength resins, can actually increase the strength of a tooth by up to 75 percent. As a result, they can last from 10 to 30 years. In some cases, where the damage to the tooth is not extensive enough to merit an entire dental crown, onlays can provide a very good alternative.
