A “C” clasp as used in a dental partial can be soldered to a labial bow to create extra anterior retention for any removable orthodontic appliance. This is often done when moving anterior teeth. To make this clasp more retentive, it is usually used in conjunction with a dental composite buccal button.

This composite undercut will allow the clasp to snap into position. All soldered clasps need extra care when adjusting them, as the solder joint when handled improperly is a potential point of breakage.
