Fig. 1—A close up of an all-Valplast lower partial denture replacing two lower molars. These all-Valplast partials are the most esthetic option available today for partial dentures.

Valplast is a flexible base resin ideal for partial dentures or unilateral restorations. The biocompatible nylon and thermoplastic resin of Valplast provide an ideal degree of flexibility and stability when processed and finished to the recommended thickness.
Additionally, the color, shape and design of Valplast partials blend seamlessly with the natural appearance of the gingival tissues, making the prosthesis nearly invisible. The strong, durable clasps snap securely and comfortably into place around the existing natural dentition and gingival. Since the strength of the Valplast resin does not require a metal framework, it eliminates the metallic taste that many patients complain about. It also enables the partial to be fabricated thinly enough with nonmetal clasps to avoid the bulky feeling often associated with large, nonesthetic traditional metal partials.
I have found that study models are useful in helping to communicate to the patient what their material options are for removable restorations. I have three models available for patients to inspect: a traditional cast metal partial, an all Valplast partial, and a Valplast partial with a cast lingual subframe and Valplast clasps. In cases of large edentulous areas, this third option works well to provide additional support while still addressing the patient's desire to have the most esthetic clasps available. Patients seem most naturally drawn to the Valplast study model, and I can't recall the last time a patient requested a metal based partial with all other factors being equal.
