What does “Dental inlay” mean?
An inlay is a partial restoration that is manufactured separately to fit the missing part of the tooth and then fitted and fixed. Typically, the defect is repaired without covering the cusp of the chewing surface.
What damages are considered?
The filling is selected by evaluating the extent of recovery and the remaining tooth wall. If the cusps are weak or fissured, an onlay that covers the cusps or a wider restoration may be needed.
How do I make and install it?
The damaged area is prepared, and the restoration is made from an impression or scan. Its fit to the tooth, contacts with adjacent teeth, and bite are checked before it is secured using a method appropriate to the material.
Is this different from the material name?
Inlay refers to a form of restoration. Inlays can be made even if they are made of different materials, such as ceramic, resin, or metal, and when selecting one, the extent of damage and material characteristics are also considered.
Frequently Asked Questions
Are inlays and onlays the same?
An inlay fills a defect within the area bounded by the cusps, while an onlay covers one or more cusps. The actual area covered distinguishes them.
Must I visit twice?
In many cases, the visit is divided into separate production, but depending on the production method such as CAD/CAM, same-day installation may be possible. The actual schedule will be determined by the course of treatment.
