The Simplified Posterior Direct Flowable Composite Bridge Restoration without Reinforcing Fibers: A Case Report

Abstract

 Purpose: In cases of a single-tooth edentulous space in the posterior region, we usually consider either a 3-unit fixed partial denture or an implant. However, minimal invasive treatment with resin composite is still the best option in some situations. This case report describes a minimal invasive and simplified direct composite bridge restoration without reinforcing fibers.

 Case: A 29-year-old female patient presented with a missing mandibular left first molar that had been recently extracted because of root fractures that had made the tooth unrestorable. A two-step self-etch adhesive system was applied after additional phosphoric acid etching of enamel surfaces which were slightly cut. Only flowable resin composite was used for the fabrication of the direct resin composite bridge. The prognosis after 9 months was good.

 Conclusion: A technique for using flowable composite resin to construct a direct resin composite bridge was demonstrated. It is important to consider the direct composite restoration option even for single-tooth replacement cases in the posterior region when the clinical and economic circumstances preclude an implant or fixed partial denture as a treatment choice. Direct composite bridge restoration is a valid treatment option for esthetic and functioning dental restoration when used under appropriate clinical circumstances. It is also important to note that the eventual repair or replacement of this restoration is much easier in comparison to dental ceramics as the substrate is composite resin. For clinical patients such as the one presented in this paper, the direct resin composite bridge is satisfactory for their restorative needs. However, further clinical research is necessary to verify the clinical effectiveness of direct bridge restorations.
