Dental crown prostheses designed to restore a tooth by fitting around the remains of the tooth and covering the entire natural crown surface (i.e., complete or total artificial crowns). Complete crowns are precision fitted and cemented to the surrounded tooth so that the patient cannot remove them. These prostheses are typically custom-made devices made of cast metal alloys (e.g., steel, gold). Total dental crown prostheses are available with a metal structure covered with porcelain or resins for esthetic reasons or as cast metal crowns with porcelain fused on the surface. Preformed crowns intended for temporary use are also available; they are used mainly in pediatric patients to cover primary teeth.
