“…Increased filler loading allows excellent strength and durability to withstand the stresses of the dentition and the oral cavity [ 24 , 25 ]. This result was supported by failure mode analysis, where an increased mixed failure percentage (80%) (Failure include the bonded interface plus cohesive failure in the tooth substrate) was shown in group E. Cohesive failure in the tooth structure confirms that this tooth fragment reattachment technique improve the fracture strength due to increasing the stiffness of tooth restoration complex [ 26 , 27 ].…”

Purpose: comparing the influence of different tooth preparation and bonding techniques on the fracture resistance of tooth fragment reattachment. Materials and method: Ninety bovine central incisors were selected. Fifteen teeth act as a control (Group A). Experimental specimens were sectioned at the mesial-incisal proximal edge 3 mm from the incisal edge in a labio-lingual direction at 25degree inclination apically. Experimental specimens were then divided into five groups according to the tooth reattachment techniques utilized; Group B: no tooth preparation þ Cured bond þ Flowable composite; Group C: no tooth preparation þ Uncured bond þ Flowable composite; Group D: Bevel þ bond þ Flowable composite; Group E: Over-contouring þ bond þ Nanohybrid composite; Group F: Over-contouring þ bond þ Flowable composite. Specimens were subjected to thermocycling between 5 C and 55 C for 500 cycles with 30 sec. dwell time. Fracture strength was evaluated using universal testing machine. Data was analyzed using One-way ANOVA.Results: There was a statistically significant difference between Group A and all the experimental groups, p < .001. Group E showed the highest statistically significant fracture resistance mean value compared to other experimental groups, while the lowest mean value was found in Group B. Conclusion: Though, none of the tested techniques resulted in fracture resistance similar to that of intact teeth, over-contouring technique with nanohybrid composite application showed better performances compared to the other techniques tested in the current study. Bonding plus flowable resin composite application with no additional tooth preparation and placement of a bevel are not suggested due to the low fracture strength achieved.

“…The composition of the polymer matrix and fiber orientation has a major role in the bonding ability and durability of the prosthesis. It has been concluded that pre-impregnated fibers with light polymerizable dimethacrylate resin systems containing linear polymers form a semi-interpenetrating polymer network after being polymerized, thereby offering more interfacial adhesion of the composite, higher durability, and high strength [ 8 ]. Composite reinforced fibers result in higher mechanical strength and toughness and less fatigue [ 9 ].…”

Sudden tooth loss can be a traumatic experience that affects a child psychologically and hampers social skills in today’s world, in which appearances seem to matter from a young age. The child becomes afraid to smile freely. Besides appearances, missing anterior teeth can hamper clarity in speech. Many approaches have been described in the past, such as the use of a removable partial denture, functional Nance appliance, Groper’s appliance, and resin-reinforced fiber composite/acrylic pontic. We report the case of a child who lost a deciduous tooth as a result of trauma. The restoration was performed using fiber-reinforced resin and a natural avulsed tooth as pontic, which restored esthetics and function.

“…However, the author concluded that the group that was reinforced with S glass recorded a superior flexural strength than that of the E glass in the experiment conducted. Patnana et al (2020) assessed the fracture resistance of different filler composites, including glass-fiber-reinforced composites using different failure patterns and fracture types [15]. The authors concluded that polythene and glass-reinforced composites exhibited enhanced fracture resistance properties compared to traditional particulate filler composites [15].…”

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.
