| Abstract | |
| Anewly reported nylon-based denture material has the property of high flexibility and
the possibility of using this material in non-metal clasps for partial dentures was suggested. The purpose of
this study was to determine the mechanical properties of a nylon-based resin material. The bending characteristics
of the following materials were examined: nylon resin (Lucitone FRS), heat-cured polymeric resin, PMMA injection-molded
resin, and polycarbonate resin. The modulus of elasticity and maximum bending stresses were calculated from
the resulting load-deflection curves. Lucitone FRS elastic modulus was statistically significantly the lowest.
The maximum bending stress of Lucitone FRS was intentionally low compared to other materials. However, Lucitone
FRS possesses bend stress equal to other materials. Specimens of Lucitone FRS did not fracture, but bent excessively.
The high flexibility of the nylon resin, as demonstrated by its low modulus, indicates its potential use in non-metal
clasps for partial dentures. Key words: Nylon-based dentures I Elastic modulus I Metal-free dentures. |
