Practical application of polyurethane and Velcro in maxillofacial prosthetics.
A procedure is described for the fabrication of an extraoral prosthesis with an acrylic resin substructure that retains a magnet sealed from the environment by a polyurethane liner. Velcro is used to enhance the bond of the acrylic substructure to the silicone prosthesis. This procedure results in improved retention of the acrylic resin substructure and protection of the magnet with an encapsulating polyurethane liner.
