9.11.2 Cast adhesive copings

This type of restoration offers two main advantages over preformed metal crowns:

• avoids unnecessary approximal reduction;


• enables margins to remain supragingival.

However three disadvantages are:

• still needs local analgesia;


• takes two visits to complete;


• technique is more expensive.
