Abstract

This study aims to evaluate the fracture resistance of acrylic resin used in temporary prosthesis with an extension cantilever, using glass fibers treated with silane as reinforcement, varying the distribution and positioning within the matrix. Fifty specimens were produced and divided equally into five groups: Group I, without reinforcement; Group II, reinforced with continuous, concentrated and aligned fibers; Group III, enhanced with simple fiber laminate; Group IV, a doubly reinforced fiber laminate; Group V, reinforced with fibers surrounding the implants and parallel to the occlusal surface. There was statistical variation between Groups I and III, I and IV, I and V, II and III, II and IV, II and V, and III and IV. The results demonstrated that temporary prosthesis reinforced with glass fibers treated with silane exhibited an increased resistance to fracture.
