“…17,18 Unidirectional fibers give anisotropic mechanical properties to the FRC and can effectively reinforce the composite in one direction parallel to stress direction, if adequate adhesion between the composite and fibers exists. 19,20 However, if unidirectional fibers are placed in the direction of perpendicular to stress, no reinforcing effect is provided as described by Krenchel. 21 When loading the FPD with the steel ball to the occlusal fossa having inclined surfaces of buccal and lingual cusps facing the fossa, the pontic was subjected to compressive, tensile and shear forces.…”

“…[23][24][25][26][27][28][29][30] They have a wide range of applications, including orthodontic treatment, 31 such as splints for periodontally-involved teeth, [32][33] reinforcement for resin composites, 34 the fabrication of non-metallic endodontic posts, [35][36][37][38][39] reinforcement of denture bases [40][41][42][43][44] and reinforcement for non-metallic crowns and fixed partial dentures. [25][26][45][46][47][48][49][50][51] It has been reported that the embedding of fiber inserts into composites results in strengthening the restoration, particularly large ones, with improved fracture resistance. 30 This study determined the effect of glass and polyethylene fiber inserts on reducing the gingival marginal gap in Class II resin composite restorations with gingival margins on the root surface.…”

Fiber inserts incorporated at the gingival floor of Class II composite restorations resulted in a significant reduction of microleakage scores as compared to restorations made without inserts. This may lead to a reduced incidence of recurrent caries. SUMMARYPurpose: This investigation evaluated the effect of glass and polyethylene fiber inserts on the microleakage of Class II composite restorations with gingival margins on root surfaces. Methods: Fifty-four intact molars were sterilized with Gamma irradiation and mounted in acrylic bases. Class II slot cavities were made on both proximal sides of each tooth (3 mm wide, 1.5 mm deep) with the gingival margin on the root surface. The teeth were divided into nine groups, according to the technique of restoration and type of bonding agent. Filtek P-60 (3M/ESPE) was used to restore all cavities. Two types of fiber inserts were used: glass fiber (Ever Stick, StickTech) and polyethylene (Ribbond-THM), with three bonding agents being employed: Scotch Bond Multipurpose (3M/ESPE), Clearfil SE Bond (Kuraray) and Xeno IV (Dentsply). In the experimental groups, 3 mm long fiber inserts were inserted into restorations at the gingival seat. The control groups had no fiber inserts. The restorations were made incrementally and cured with LED light (UltraLume5, Ultradent). The restored teeth were stored in water for two weeks, then thermocycled for 3,000 cycles (5°C and 55°C). The tooth surfaces were sealed with nail polish, except at the restoration margins. The teeth were immersed in 2% procion red dye solution, sectioned and dye penetration was assessed to determine the extent of microleakage

“…Reinforced ceramics such as InCeram (Vita, Bad Säckingen, Germany) and Empress 2 (Ivoclar, Schaan, Liechtenstein) 9,10 and composites 11,12 such as Targis/Vectris (Ivoclar), Sculpture/Fibrekor (Jeneric/Pentron, Wallingford, Conn.), and Belleglass/Connect (Kerr, Orange, Calif.) have been proposed for the fabrication of metal-free AFPDs. The brittleness of ceramics makes this project difficult.…”

THE JOURNAL OF PROSTHETIC DENTISTRY VOLUME 87 NUMBER 5have proven their clinical reliability in combination with the metal-ceramic technique. 1,2 The advent of metal-free restorative materials, however, has led to the use of indirect composite or ceramic fixed partial dentures (FPDs) as an alternative to conventional metal-ceramic AFPDs. Better bonding properties to composite cements, more appropriate biomechanical behavior, and enhanced esthetics are expected with the use of composite or ceramic compared to metal alloys. alternative to conventional metal-ceramic adhesive fixed partial dentures (AFPDs). Little information about the adequate restorative material and tooth preparation design for inlay-anchored AFPDs is available to the clinician.Purpose. The purposes of this simulation study were: (1) to use 2-dimensional finite element modeling to simulate stresses at the surface and interface of 3-unit posterior AFPDs made with 6 different restorative materials, and (2) to investigate the influence of 3 different abutment preparation configurations on the stress distribution within the tooth/restoration complex. Material and methods.A mesio-distal cross-section of a 3-unit AFPD was digitized and used to create 2-dimensional models of the periodontal membrane, supporting bone, different restorative materials (gold, alumina, zirconia, glass-ceramic, composite, and fiber-reinforced composite), and different abutment preparation configurations (interproximal slots vs. 2-surface [MO, DO] vs. 3-surface [MOD]). A simulated 50-N vertical occlusal load was applied to the standardized pontic element. The principal stress within the restorative materials, stresses at the tooth/restoration interface, and surface tangential stresses at the level of the pontic were calculated in MPa from the postprocessing files and compared to each other.Results. All materials and tooth preparation design exhibited a similar stress pattern, with a definite compressive area at the occlusal side of the pontic, a tensile zone at the gingival portion of the pontic, and tensile stress peaks in the abutment/pontic connection areas. Among isotropic materials, standard non-reinforced composites exhibited better stress transfer and reduced tensile stresses at the adhesive interface than ceramics and gold. Optimized placement of the glass fibers within the composite resulted in similar stress distribution when tested in 2-surface abutment preparation configuration. There was no detectable influence of preparation design on the behavior of the pontic area. Among all 3 preparation designs, only the DO design exhibited almost pure compression at the interface. Conclusion.
