southend clasp 

Hope it helped. As will the others demonstrations!

Thanks for commenting. The Southend clasp is used to keep the anterior part of yhe appliance in place. It is a fixative, or retentive component and is better suited for use on anterior teeth. Adams clasps can damage the lips and don't engage undercuts adequately.

@@dentaltechnology-cardiffme4022 any reason why using this than passive labial bow

@@pingmichael878 you can use this for the teeth it contacts, but it is a fixative component rather than a retainer, which the labial bow is.
