Crowns are synthetic caps, nowadays usually made of a metal free material like porcelain fused to Zirconia (ceramic), press ceramic: e.max, or (PFM: Porcelain Fused to Metal), placed on the top of a tooth.
Crowns are typically used to restore a tooth’s function and appearance following a restorative procedure such as a root canal treatment. When decay in a tooth has become so advanced that large portions of the tooth must be removed, crowns are often used to restore the tooth.
Crowns are also used to attach bridges, cover implants, prevent a cracked tooth from becoming worse, or an existing filling is in jeopardy of becoming loose or dislocated. Crowns also serve an aesthetic use, and are applied when a discolored or stained tooth needs to be restored to its natural appearance.
Bridges are natural-looking dental appliances that can replace a section of missing teeth. Because they are custom-made, bridges are barely noticeable and can restore the natural contour of teeth as well as the proper bite relationship between upper and lower teeth.
Porcelain fused to Zirconia and PFM: Porcelain Fused to Metal materials are usually used to make bridge appliances.
Appliances called implant bridges are attached to the abutment of the implants and usually made screw retained.
