Anterior fiber-reinforced composite resin bridge: a case report

A variety of therapeutic modalities, from implants to conventional Maryland bridges, can be used for the replacement of a traumatically missing anterior tooth. The reinforcement of composite resins by fibers improves their fracture toughness and resistance. Fiber-reinforced composite (FRC) bridges can be a good alternative to conventional prosthetic techniques. The purpose of this article was to present a clinical case of a single tooth replacement by means of a polyethylene FRC bridge. A semi-direct technique was used to fabricate a Maryland-like composite bridge for the replacement of a missing central permanent incisor. The bridge fabrication was done in the dental office using a fast-setting polyvinylsiloxane die material and a state-of-art restorative composite resin. This technique offers a conservative, esthetic, and noninvasive treatment. Moreover, this technique is economically more acceptable, nonirritating, and noniatrogenic. Polyethylene FRC bridges can be considered as a permanent treatment or, in the case of implant placement after the end of the growth period, as a long-lasting reversible provisional treatment.
