This paper documents the tremendous improvements made over the past four decades in materials and techniques for minimally invasive esthetic restorations following traumatic injuries to the maxillary anterior teeth. The etiology of traumatic injuries is discussed before presenting a case report of a traumatic injury treated in the 1970s. This case demonstrates not only the poor color stability of the original autopolymerized resins, but also the excellent longevity and color stability of later generations of visible light–cured composite resins. In addition, the case demonstrates the significant benefits of the minimally invasive approach, which was made possible by the acid-etch technique. The improvements made over the years in composite resin materials, and in refinements to the technique initially developed in the late 1960s for the conservative restoration of fractured anterior teeth, are shown in additional examples. This paper demonstrates cases involving composite resin Class IV restorations of fractured anterior teeth and also the reattachment of the retrieved fragments of anterior teeth.
