What Are Porcelain Inlays and Onlays?
They are porcelain-based fillings prepared by the technician in the laboratory. Similar to conventional filling, the cavity or the old filling of the tooth is removed. Dental impressions are taken and sent to the laboratory. They are precisely manufactured with advanced technology. It is attached to the tooth with special adhesives. It is the ideal treatment option in cases where a very large filling is required and porcelain veneer is not desired. The integrity of the inlay fillings with the tooth is very good. Concordance of the tooth with the gum is excellent. Since they are glued with very strong adhesives, the risk of breaking down is insignificant compared to composite and amalgam fillings. The only disadvantage is the higher cost relative to other fillings.
Inlay or onlay systems may be preferred in case of very large decays or loss of the tooth, if the tooth cannot be restored with a composite filling and the patient does want dental veneers. After the dental impression is obtained with a silicone or polyether-based material, the impression is sent to the laboratory. Onlay or inlay is manufactured with advanced technology and attached to the teeth with special adhesives and thus, the lost dental tissue is replaced.
