Long-term effects of storage and thermal cycling on the marginal adaptation of provisional resin crowns: a pilot study.


STATEMENT OF PROBLEM Provisional resin crowns may be used for an extended period while complex treatments are completed. The crowns function intraorally; therefore, moisture absorption and thermal cycling may affect the physical properties of acrylic resin, causing a change in marginal gap size. PURPOSE The purpose of this pilot study was to examine the… (More)
