Onlay / Inlay
Dental onlays or inlays are restorations used to replace large fillings, restore teeth with cracks or extensive loss of tooth structure. A dental inlay is similar to a filling and fits inside the cusp tips (top edges) of the tooth. A dental onlay is more extensive and extends over the cusps of the treated tooth. Onlays usually have the advantage of being more conservative than a full coverage crown.
