Title: Conventional composite restoration v/S fiber reinforced composite restoration
Abstract:
Missing of tooth structure often occurs due to trauma, caries, and cavity preparation. Restoration is needed to replace the missing tooth structure. An ideal restoration in a tooth should be able to maintain the esthetics and function, preserve the remaining tooth structure, and prevent microleakage. One of the objectives of tooth restoration is to reestablish its fracture resistance when subjected to occlusal load. In final restorations, composite resin shows an increased resistance to fracture, as it replaces biological tissue esthetically and functionally. A successful restoration is determined by its longevity in the oral cavity, and other factors, such as cavity design, size of cavity, type of teeth, and restoration material. 5 The prevailing reasons for restoration failure are fracture and secondary caries. Fracture is a considerable risk to posterior restorations, regardless of the lifespan or the age of these restorations. Newly-recommended method for restoring large cavities is the biomimetic approach of using short fiber-reinforced composite (SFRC) as dentine-replacing material. With their improved mechanical properties and wear resistance, and given their more favorable cost, resin composites have, for many, become the material of choice not only for dentine replacement butalso for the restoration of the whole posterior tooth in the posterior region.2 Clinically, it is widely recommended that an incremental layering technique be used in order to reduce the resin polymerization stress and to develop better mechanical properties.To locate the ideal composite material for the restoration of large class I and II cavities in posterior teeth has long been a vital issue in restorative dentistry.2 To be able to construct a perfect composite restoration, one must be aware of the potential risk factors and characteristic types of failure in the posterior regionThe rationale behind the usage of fiber reinforcement is partly to internally strengthen the structurally-compromised tooth and partly to prevent the occurrence of fractures. The efficacy of fiber reinforcement is dependent on several factors, including the resins used, the length of the fibers, the orientation of fibers, the position of the fibers, the adhesion of the fibers to the polymer matrix, and the impregnation of the fibers into the resin.6 The reinforcing effect of the fiber fillers is based on stress transfer from the polymer matrix to the fibers. However, the individual fibers also act as crack stoppers. Thus, the sole purpose of the present poster was to exclusively review the available literature on the biomimetic restorative technique by using SFRC material, and to give clinicians a comparative overview of this method with traditional composite techniques in terms of their biomechanical stability
