“…Leveraging the advances in adhesive bonding technology, the conservative approach of minimally invasive dentistry allows the esthetics and function of anterior teeth to be restored with adhesive fixed partial dentures. Fueled by increasing interest in metal-free esthetic dentistry, glass fiber-reinforced composite (FRC) has been used in myriad dental applications [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] . Of particular interest to this paper are the adhesive fixed partial dentures (AFPDs), which have been favorably reported because of their good clinical performance [18][19][20][21] .…”

Using finite element analysis (FEA), this study investigated the effects of the mechanical properties of adhesive resin cements on stress distributions in fiber-reinforced resin composite (FRC) adhesive fixed partial dentures (AFPDs). Two adhesive resin cements were compared: Super-Bond C&B and Panavia Fluoro Cement. The AFPD consisted of a pontic to replace a maxillary right lateral incisor and retainers on a maxillary central incisor and canine. FRC framework was made of isotropic, continuous, unidirectional E-glass fibers. Maximum principal stresses were calculated using finite element method (FEM). Test results revealed that differences in the mechanical properties of adhesive resin cements led to different stress distributions at the cement interfaces between AFPD and abutment teeth. Clinical implication of these findings suggested that the safety and longevity of an AFPD depended on choosing an adhesive resin cement with the appropriate mechanical properties.

“…To reinforce hybrid resin with glass fibers, a bundle of fibers are to be immersed in a resin monomer (bonding agent in this study) and firmly bonded. Previous studies reported that fractures of fiber-reinforced hybrid resins were usually initiated at the interface between the fibers and resin matrix [8][9][10] . It is therefore noteworthy that the bond strength between fibers and resin matrix differs significantly with bonding agents embedded with fibers, whereby the latter is thought to have a significant influence on reinforcing effect.…”

, Single Bond (SN)) impregnated with fibers on bending strength. FB attained the highest bending strength of 570 MPa, whereas SN exhibited the lowest value of 224 MPa, which meant that the bending strength of FB was 2.5 times higher than that of SN. Results of this study suggested that the bending strength of fiber-reinforced hybrid resin was significantly affected by bonding agents impregnated with fibers. Therefore, selection of bonding agent for hybrid resin restoration requires careful consideration of product composition to ensure an optimal bonding agent-fiber combination, thereby imparting improved mechanical properties to the resultant dental restoration.

“…As with any prosthetic devices, the materials used for fabricating FPDs play a pivotal role in determining the success rate and longevity of these dental restorations. In the case of FRC FPDs, numerous studies were carried out to examine the FRC material from different perspectives: mechanical properties [7][8][9][10] , material development in terms of flexural strength 11) , biocompatibility 12) , fatigue analysis 13,14) , structural analysis in terms of stress distribution 15,16) , and optimal design of FRC framework to obtain the maximum reinforcement effect for FPD 17,18) . Despite the much that is already known about the material properties of FRC framework and particulate-filled composite veneer through the numerous laboratory and clinical studies, much remains to be known about the mechanical behavior of FRC FPDs with respect to displacement and stress magnitude and distribution pattern which were induced during functional loading.…”

The aim of this study was to evaluate the influence of connectors under two different loading conditions on displacement and stress distribution generated in isotropic hybrid composite fixed partial denture (C-FPD) and partially anisotropic fiber-reinforced hybrid composite fixed partial denture (FRC-FPD). To this end, two three-dimensional finite element (FE) models of three-unit FPD from mandibular second premolar to mandibular second molar -intended to replace the mandibular first molar-were developed. The two loading conditions employed were a vertical load of 629 N (applied to eight points on the occlusal surface) and a lateral load of 250 N (applied to three points of the pontic). The results suggested that the reinforcing fibers in FRC framework significantly improved the rigidity of the connectors against any twisting and bending moments induced by loading. Consequently, maximum principal stress and displacement generated in the connectors of FRC-FPD were significantly reduced because stresses generated by vertical and lateral loading were transferred to the reinforcing fibers.
