Inlays and Onlays are the middle ground solution between fillings and crowns (tooth cap). Dental inlays and onlays are aesthetic treatment methods used when there is not enough bone tissue to fill and tooth damage is not substantial enough to use a crown.
The difference between them is in the area of coverage of the teeth. An inlay is similar to fillings, however it is placed between the tubercles on the chewing surface of the teeth. On the other hand, an onlay is often used to cover one or more dental tubercles. However, an onlay is often used to cover one or more dental tubercles.
Inlays and onlays are made up of a ceramic or fibre-reinforced composite.
For teeth that received root canal treatment or severely decayed, an insufficient volume of tooth tissue after the removal of decay is observed. The desired anatomic form and contact can be achieved beforehand since the inlay or onlay is prepared on a mock-up. Also, the material is more resistant to erosion and chewing pressure than conventional filling material.
The lifespan of inlays and onlays depends on the material from which they are made, the condition of the original tooth treated with inlay or onlay, the masticatory force , oral hygiene of the patient, and whether regular visits are made to the dentist. Inlays and onlays usually function properly for decades.
Maintaining a daily oral care routine which includes brushing the teeth, flossing, and keeping regular dental check-ups are needed for the proper care of inlays and onlays.
