Inlays and Onlays
What is an Onlay? What are the benefits?
This type of restoration is indicated where a large portion of the tooth structure is missing or damaged (usually greater than 1/3 of the tooth) due to fracture, large defective fillings, decay, but there’s still a good amount of sound tooth structure present that a crown is not necessary. An onlay is a smaller restoration than a crown and is a conservative way to restore a tooth. It can be made of metal, porcelain and resin. Resin reinforced onlay is made under heat, light and pressure creating an extremely durable, wear resistant, and strong restoration compared to fillings done in the office. It is cemented or bonded to the tooth which create a tight seal between the tooth and onlay. These restorations typically last longer than resin fillings(done in office) and preparation requires less tooth removal than crowns. It takes two visits to complete this durable, conservative treatment.
