Application of a Glass Fiber-reinforced Composite Material to Clasps: Study on Adhesive Method of Veneering Composite

Stress Analysis of Clasps Made of Glass Fiber-reinforced Composite Material Using Three-dimensional Finite Element Method: Influence of Shape in Cross and Longitudinal Sections of Circumferential Clasp Arms

“…Based on this finding, it was thus more advantageous to employ the thickness of clasp arms to enhance resistance to a behavior like torsion. 4. Comparison between patterns of stress distribution of orthotropic material and those of isotropic material With both orthotropic material (FRC) and isotropic material (Co-Cr) of the same geometry, their stress distribution patterns were similar to each other (Figs.…”

“…Table 2 shows the orthotropic material's properties used in this study. These elastic constants were set by assuming the use of Vectris Pontic, which we had used for material testing and clinical trials [1][2][3][4] . Elastic modulus 33 (E33), which represented longitudinal elastic modulus, was obtained from our material testing measurements 3) .…”

“…Results suggested that FRC materials could be used for clasps. Based on these results, we further performed clinical trials 4) . In clinical practice, FRC clasps are required to be coated by composite resin to prevent exposure of fibers which could hurt the oral mucosa.…”

Optimum design for glass fiber-reinforced composite clasps using nonlinear finite element analysis

“…Nine elastic constants (Table 2) were used as in our previous study 14) . These were set by assuming the use of Vectris Pontic (Ivoclar Vivadent, Amherst, NY, USA), which we used for material testing and clinical trials [1][2][3][4] . Elastic modulus 33 (E33) parallel to the orientation of the fibers (i.e.…”

“…On the basis of results of these studies, we also performed clinical trials 4) . In clinical practice, FRC clasps are coated with composite resin to prevent exposure of fibers and injury to the oral mucosa.…”
