[Esthetic repair of crown margins with composite. A case report].

Gingival recessions can cause severe aesthetical problems, especially when associated with the exposure of the margin of crown or bridge restorations. When complete root coverage can not be achieved by periodontal surgery techniques, prosthetic restorations are usually replaced to improve the aesthetic situation. This clinical report describes the application of a composite repair filling as an alternative technique to correct the restoration margin and cover the exposed root surface. From the published literature it is known that metallic and ceramic surfaces can be repaired adhesively using composite materials. This procedure is less costly and invasive, but provides satisfactorily aesthetic results.
