Inlays and onlays also called partial crowns. The onlay or inlay is fitted onto the existing tooth, which is used as the base.
The inlays and onlays are used to strengthen the tooth, restore its shape, and prevent further damage. Inlays are placed directly on the tooth and can only be used if there is no damage to the cusps of the tooth. Contrary to the inlay, the onlay is used when there is more extensive damage.
The first part of the procedure involves the removal of the decayed area of the tooth. Following the removal, a mold of the tooth is casted and sent to a dental lab. The dental lab will create a restoration made from either porcelain, gold, or a composite resin. While the restoration is being prepared (usually 2-3 weeks), a temporary onlay or inlay will be set onto the tooth.
When the final inlay or onlay is ready, the dentist will cement it onto the tooth.
The final result should be a natural looking tooth.
