Inlays and onlays are often referred to as partial crowns. They cover only the damaged part of the tooth and preserve existing good tooth structure. An inlay is done when there is no damage to the cusps (tips) of the tooth and the inlay can be placed right into the tooth preparation. An onlay is used when one or more of the cusps need restoration.
The decayed area of the tooth is first removed during the procedure. We utilize E4D CAD-CAM technology to fabricate the inlay or onlay. The inlay or onlay is stained and glazed and bonded to the tooth using a resin cement. The procedure is completed in one appointment.
