ABSTRACT:
A prefabricated thermoplastic clasp from whose structure a permanent clasp is formed around teeth anchoring partial removable prosthesis and dentures without the necessity of fashioning metal clasps by the lost wax method or by plastic clasps by injection molding processes. The prefabricated clasps are easily contoured by applying heat to the area which the technician wishes to shape and bend. This allows the clasp to be a one step operation thereby omitting time consuming procedures.
