Abstract

Restorations are customarily anchored by small undercuts within the dentin, when a large portion of crown is missing because of caries or for other reasons such as fracture. It is difficult to obtain this anchorage. There are many features that provide resistance and retention form to the amalgam such as pins, locks, coves, slots etc. Bonding also provides anchorage of restorative materials to the dentin. It has been seen that the mutilated teeth are successfully restored with the use of pins. These are called the complex amalgam restorations. Thus are the restorations which involve more than two surfaces of the tooth with or without cusp capping. These complex amalgam restorations are used occasionally as an alternative to indirect restorations.
