Dental crown prostheses designed to restore a tooth by fitting around the remains of the tooth and covering more than half but not the entire natural crown surface (i.e., partial artificial crowns). Partial crowns are precision fitted and cemeted 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). Partial crown prostheses are usually classified according to the fraction of the crown that they cover (e.g., one-half, three-quarters).
