These are porcelain or resin restorations for back teeth. They are placed instead of a filling and are the restoration of choice when the damage to the tooth or the filling they will replace, is larger than ½ of the diameter of that tooth. They are constructed in a lab, after the dentist has taken an impression, and cover the cusps of the tooth, thus protecting it from fractures. They are very resilient restorations of the highest aesthetic quality.
