The Effect of Fiber Reinforcement Type and Water Storage on Strength Properties of a Provisional Fixed Partial Denture Resin GU ¨ LAY UZUN School of Dental Technology Hacettepe University, Sihhiye 06100 Ankara, Turkey F _ IL _ IZ KEYF* Faculty of Dentistry Department of Prosthodontics Hacettepe University Sihhiye 06100, Ankara, Turkey ABSTRACT: Fracture resistance of provisional restorations is an important clinical concern. This property is directly related to transverse strength. Strengthening of provisional fixed partial dentures may result from reinforce- ment with various fiber types. This study evaluated the effect of fiber type and water storage on the transverse strength of a commercially available provisional resin under two different conditions. The denture resin was reinforced with either glass or aramid fiber or no reinforcement was used. Uniform samples were made from a commercially available autopolymerizing provisional fixed partial denture resin. Sixteen bar-shaped specimens (60  10  4mm) were reinforced with pre-treated epoxy resin-coated glass fibers, with aramid fibers, or with no fibers. Eight specimens of each group, with *Author to whom correspondence should be addressed.
