Repairing defective amalgam fillings is a viable option. Studies-although not definitive-show similar long-term outcomes between repair on the one hand and removal and replacement of the filling on the other, with repair being less invasive. Clinical criteria have been proposed to guide the dentist in deciding whether to remove or repair an amalgam restoration. No consensus has emerged to establish a protocol regarding the material or adhesive to be used. One of the key points is the preparation of the amalgam's surface. This surface must maximize bonding with the repair material; it can be prepared by alumina sandblasting or silicification.
