Inlay – This restoration is made of porcelain or some type of metal that substitutes for a filling. A dental impression is made and the inlay is fabricated to be cemented in place. When a tooth is going to be compromised by additional fillings due to a breach in the tooth from a crack or decay, the inlay becomes the ideal option while saving and strengthening the tooth.
Onlay – When the cusp of a tooth is impacted, but the integrity of the tooth will be in jeopardy with a soft filling, a dental onlay may be indicated. The cusp is the part of the tooth that can be pointed or rounded that extends beyond the chewing surface of the tooth. This restoration can also be made from porcelain or metal, requires a dental impression, and is made for permanent cementation when ready.
Crown – When a fracture or deep dental decay indicates the need for a full crown, the dentist will remove a considerable amount of the tooth’s structure, take a dental impression, and place a temporary protective covering on the prepared tooth while the crown is being made.
In addition to this application, the crown is also used as the final restoration to seal a tooth following a root canal; to cover a dental implant; and as an anchor for a fixed dental prosthesis. The crown has been used with much success, and can be replaced as needed but usually lasts for many years.
With the increased use of porcelain in all of these applications, the tooth is fortified with a material that is strong and stain resistant. In addition, the restorations are tooth colored and made to match surrounding dentition so they are virtually invisible as dental corrections.
If a dental lab is used to fabricate any of these restorations, a minimum of two dental visits are required. The first step involves tooth preparation with seating taking place in about two weeks. Your dentist will make sure to use the correct application to make needed repairs.
