Various self-curing resins are used in provisional restorations and denture repairs. But the existing products cause problems, such as color stability and durability.A new self-curing resin, UNIFAST II® which was recently developed to solve these problems, was evaluated as to clinical safety and usefulness. The evaluation was made on provisional restorations in 60 clinical cases as to reactions of pulp and periodontal structures, and also as to color stability and abrasion of the restorations.This examination was performed from 14 to 235 days after restoration was completed. Denture repair cases were evaluated in 15 clinical cases as to the condition of the denture supporting mucosa, fitness of the denture, color stability and durability from 91 to 279 days. As a result, the new self-curing resin did not show any deteriorating effects on the pulp and the periodontal structures.No clinical problem was observed in denture repair cases, either.From these clinical experiments, the new-self-curing resin was judged to be a safe and useful material.
