INLAYS AND ONLAYS
Many people have never heard the terms “inlays and onlays,” or they don’t understand their place in dentistry. These dental repairs take their names from the location on the tooth where they are used.
At Prosthodontics of New York, we use inlays and onlays as options for restoring normal tooth structure when a tooth is decayed or otherwise damaged. These are alternatives to the more aggressive treatment of a crown.Unlike fillings that are mixed and placed chairside, inlays and onlays are fabricated in our CEREC 3D design and milling system, and are then cemented or bonded onto the tooth.
There are advantages to these restorations because, unlike a typical filling that weakens the tooth, inlays and onlays do not weaken the tooth structure; they actually strengthen the tooth, adding between 50 and 75 percent more chewing force. Their names derive from their location: inlays are placed within the cusp tips of the tooth; onlays usually cover the entire chewing surface including one or more tooth cusps.
