They are usually dental restorations that can be alternatives to full coverage dental crowns. They are used primarily to repair tooth decay or other similar damage. They are durable and well-fitted for any teeth. They give teeth that are functionally and visually improved.
Inlays are bonded into the center of a tooth, while onlays are bonded to multiple points or full coverage of a tooth.
They have several benefits
- They preserve natural, healthy parts of a damaged tooth and are best used when a tooth is only partially decayed.
- They also preserve their color over time better than resin fillings.
- They are very easy to clean than full coverage restorative procedures because they are fitted at all edges.
- Inlays also seal better than composite fillings and onlays can protect weak areas of the tooth.
The whole procedures can be completed in two visits.
The first visit is the preparation stage. The dentist would take an impression of the damaged tooth. The tooth is then taken to the lab for the creation of the inlay and onlay. The inlay and onlay can be made from gold, porcelain, or resin materials, depending on the location of the damaged tooth and proper alignment of teeth. The patient may wear a temporary version of the final product, which can be created on the first visit.
On the second visit, the dentist would remove the temporary inlay or onlay is removed and the gold, porcelain, or resin model is placed. The dentist will test for a tight, stable fit before bonding it to the damaged tooth.
