Objectives: The aim of this in-vitro study was to compare flexural strength of provisional bridges made with PMMA and bis-acrylic resin with and without fiber reinforcement. Methods: A steel master model was constructed, with two metal cores fixed to a metal base at a distance of 10mm of each other in order to reproduce a simulated cast for a three-teeth bridge with an extracted molar. A metal bridge was manufactured for this cast, representing teeth 45, 46 (phantom) and 47. This master-piece was used to obtain a polyether (Impregum Regular, 3M Espe, Seefeld, Germany) matrix for the production of 10 provisional bridges for each of the three treatment groups using the following materials: A) PMMA; B) Bis-acrylic resin (ProTemp 3, 3M Espe, St. Paul, USA); C) Bis-acrylic resin + fiber reinforcement (Interlink, Angelus, Brazil). Samples of each group were fitted on the steel master model, using it as a fixed platform and tested with a Universal Testing Machine (Digimess MX5000) at a crosshead speed of 1mm/min. FS was expressed in Newtons as the load at fracture of the samples. Statistical differences were analyzed using Mann-Whitney U test with for p<0.05. Results: Mean FS values(sd) were 809.4(78.7)N for group A; 802.0(19.4)N for group B and 985.9(18.9)N for group C. There were f statistically significant differences between group C and the other two groups (p=0.0034) but not between group A and B (p= 0.05). Conclusions: Fiber reinforcement increases in vitro flexural strength of Bis-acrylic provisional bridges.
