Even in the ancient age there was an ambition to fix loose teeth. From the 1950s almost the same materials were used for splinting like today. A real breakthrough happened with the introduction of the etching method and the development of better composites as well as fiber-reinforced materials. In this paper the authors give a review of literature and their experience about the fiber-reinforced composites (FRC). Properties and use of the fiber-reinforced composites are presented, and suggestions are given how to apply the different materials for splinting, orthodontic retentive treatment, fixing traumatised mobile teeth, or temporary and long-distance provisional and permanent prostheses.
