Polyamide belongs to the polymers family, which is applied using an injection-moulding technique in the manufacture of flexible prostheses. This material provides thin, lightweight and yet resistant prostheses, which are comfortable and highly aesthetic, as the colour can be easily adapted to the oral cavity. Also for improved retention, instead of metal clasps, it has thin finger like extensions, which extend into undercuts and act as clasps. This product is ideal for those patients who are allergic to acrylic.
