“…The content of glass fiber filler in dentin replacement can increase the material's ability towards tensile loads. Following the application of a high tensile load to the tooth structure, the fiber undergoes a modification effect by absorbing and spreading the tensile load on the tooth surface [34,35]. A previous study reported relevant results to the findings of the current study, indicating that the fracture toughness and flexural strength of fiber dentin replacement were improved compared with those noted in the flowable composite resins [10,25].…”

Due to the increasing interest in direct restoration, there is a need to address the shortcomings of these restorations, mainly by increasing the longevity of complex direct restorations. The present study aimed to evaluate the tensile strength differences in the complex restoration of posterior teeth with dentin replacement constructed by fiber and non-fiber materials. The samples were extracted from the mandibular permanent-molar and prepared using a complex cavity. The cavity was subsequently restored with the centripetal incremental technique using a nano-fill composite and different base materials, namely fiber dentin replacement, non-fiber dentin replacement, and flowable composite. The universal testing machine was used to consider the tensile strength and the fracture patterns were assessed using stereomicroscopy, followed by Scanning Electron Microscopy (SEM) examination. The data were statistically analyzed using the one-way ANOVA test. No significant differences were noted in the tensile strength of the three base materials. By using stereomicroscopy and SEM, the adhesive fracture patterns were observed more clearly in the cavities with fiber-based dentin replacement, whereas mixed fracture patterns were evident in cavities with non-fiber dentin replacement and flowable composite bases. The results indicated that the addition of fiber in dentin replacement did not affect the tensile strength in the complex restoration. Therefore, dentin replacement of both fiber and non-fiber materials is applicable as a base material for complex restoration of the posterior tooth.

“…The flexural strength of the poly(BA-a) composites reinforced with 20–80 wt% GF was in a range of 250–504 MPa, which is the highest flexural strength owned to the poly(BA-a) composite reinforced with 60 wt% GF, i.e., 504 MPa. Theoretically, a variety of parameters, such as the fiber content, thickness, orientation, aspect ratio, bonding to the resin matrix, polymerization-induced stress, and variations in the intrinsic properties of the fibers and matrix, affect the mechanical properties of fiber posts [ 50 ]. Therefore, the enhancement of flexural strength of the 60 wt% GF-reinforced poly(BA-a) composite may indicate that good interfacial adhesion between poly(BA-a) and glass fiber was achieved.…”

Glass fiber post based on the new polymeric material, polybenzoxazine, is prepared and the effects of glass fiber contents on mechanical and thermal properties are evaluated. The mechanical response to externally applied loads of tooth restored with glass fiber-reinforced polybenzoxazine composite posts is also simulated by finite element analysis of a tridimensional model and compared with the response to that of a natural tooth. The reinforcing of glass fiber can help improve the mechanical and thermal properties of the polybenzoxazine influenced by the interfacial adhesion between the glass fiber and polybenzoxazine matrix, except for the relatively high mechanical property of the glass fiber. The mechanical data, i.e., elastic modulus under flexure load or flexural modulus by three-point bending test of the glass fiber-reinforced polybenzoxazine composites are agreed with the elastic modulus of dentin and then used in the finite element model. The restoration using the glass fiber-reinforced polybenzoxazine composite post provided the maximum von Mises equivalent stress at the cervical third area of the endodontically treated tooth model as similarly observed in the natural tooth. In addition, the maximum von Mises equivalent stress of the tooth restored with the glass fiber-reinforced polybenzoxazine composite post is also quietly like that of the natural tooth. The finding of this work provided the essential properties of the glass fiber-reinforced polybenzoxazine composite for dental restorations and appliances.

“…Glass fibers exist in numerous compositions such as E-glass, S-glass, D glass, AR glass, A glass, and C glass. These different forms of glass fibers have diverse uses and properties despite that they are all amorphous and formed of a 3-dimensional silica network characterized by a random arrangement of oxygen and other atoms [7]. Various advantages are associated with the use of glass fiber-reinforced composite in dental restoration.…”

Fibers can be used as restorative materials during post-endodontic treatment to avoid tooth fractures. Fibers can modify the stress by initiating a Monoblock effect that aids to dispel the stress along the tooth's long axis. Fibers can also prevent the formation of cracks due to the dispersal of stress to the fibers from the polymer matrix. Glass fiber-reinforced composite is one of the materials that can be used in dentistry for restoration. It is known that enclosing glass fibers into a resin matrix produces glass fiber-reinforced composites. The objective of this study was to evaluate the efficacy of glass fiber-reinforced composite restoration. This study utilized a systematic review that involved searching the literature and selecting articles for review based on the set criteria for exclusion and inclusion. The study established that glass fiberreinforced composite restoration recorded favorable outcomes compared to other non-fiber-reinforced composite materials and other composite materials. Glass fiber-reinforced composite materials are appropriate to be used for restoration based on their clinical efficacy.
