Monomer-Free Processing

For patients sensitive to conventional denture acrylics, we offer the option of processing our dentures using Lucitone FRS. An allergist can skin test patients for sensitivity to acrylic monomer. However, be sure to first rule out the possibility of a subclinical yeast infection. It is more common that a patient with an existing denture has a yeast infection than it is the patient is sensitive to the denture acrylic, as the monomer used to process the standard acrylic polymerizes the acrylic powder and becomes incorporated, thus being less reactive with the oral environment.

Lucitone FRS®

Lucitone FRS, by Dentsply, is a thermoplastic injectable resin for use in creating both flexible partials and small to medium sized dentures. It is a monomer free material and offers superior flexibility, transparency for optimal esthetics, and excellent stain resistance. The FRS material also resists stress fractures. Its microcrystalline structure is easy to polish, similar to that of acrylic. Restorations manufactured using FRS are very light weight and comfortable for the patient. Light pink, original, and clear shades are available.

The semi-crystaline nylon composition provides Lucitone FRS with: lucitone-frs-sample

  • Strength, flexibility, and transparency
  • High impact resistance
  • Outstanding UV and light stability,
  • Color stability
  • Low water absorption and good dimensional stability

 

FRS material cannot be relined. When relines are required, the case is rebased with new FRS
material.
