Onlays repairs larger areas
As stated above, one of the significant differences between dental inlays and onlays is that an onlay covers a larger area than an inlay. An onlay covers the cusps of your tooth, while an inlay only covers the region between the cusps.
Onlays are also known as partial crowns.
Onlays are used on the biting surface. They can be extended to cusps across your tooth, as requested by the patient. Like inlays, onlays can be designed using ceramics, gold, or composite resins. Each of these materials provides excellent durability for the patient.
