Inlays and onlays are similar to teeth fillings. The significant difference lies in the fact that the fillings are made and shaped in the patients' mouth while Inlay and Onlay, like the crowns, are made in the laboratory, using a special mould. The main advantage of this technique is that the teeth do not need to be filed down excessively. Inlays and onlays adhere better to the teeth, they are stronger than the fillings and the passages on the teeth are almost invisible.
Inlays and onlays can be made of composite, gold or ceramic.
The only difference between Inaly and Onlay lies in their sizes. Inlay is smaller because it is applied in the middle of the tooth and when in position, it is not in contact with the opposing tooth. Onlay is larger, extending over a larger area of the tooth and in contact with the opposing tooth through the bite.
Despite the fillings and inlays / onlays are very similar, the difference in their cost is significant. While fillings are made in a dental office and with different materials, Inlays / onlays are created in a dental laboratory. Their cost is therefore higher since, regardless of the work done in the dental office, the cost of the materials and the production also needs to be covered.
