Crozat clasps are typically used on first permanent molars as part of a Crozat appliance. They consist of three parts. The main body of the clasp, called the crib, is formed from one piece of wire and is tightly adapted around the entire tooth. The second wire, called the crescent, provides the retention by engaging the undercuts of the proximal surfaces.

The third part of the clasp is the occlusal rest. It passes through the lingual groove and rests tightly on the occlusal surface.
