Yes, I have only heard good things about them as a partial.
Valplast is a flexible denture base resin that has been used in dentistry since 1954 and is ideal for partial dentures and unilateral restorations. The resin is a biocompatible nylon thermoplastic with unique physical and aesthetic properties that provides unlimited design versatility and eliminates the concern about acrylic allergies. It allows your patient's natural tissue tone to appear through the material, matching the basic shade categories (medium, light pink, and meharry). Patient's report that it feels more comfortable because of the thinness and light weight. It is also guaranteed for life against breakage when fabricated and handled according to the manufacturer's specified procedures.
The Valplast Nesbit is ideal for posterior single tooth replacement and the Valplast Flipper is ideal for anterior single tooth replacement. The design of the new flexible plastic framework takes the danger out of an accidental swallowing of the appliance. In the event that someone did swallow one, it is unlikely that any damage could be done to the lining of the digestive system.

I don't recommend them for full dentures unless you are aware that if they do not fit correctly, they have to be done over, as they cannot adjust them well enough. For partials they work well. In the states, I don't know what they cost. In Mexico, they are $350 to $500 (upper or lower) approximately, depending on where you go.
