Controlled-release, tetracycline-impregnated periodontal fibers offer a promising treatment for recurrent adult periodontitis when they are used as an adjunct to scaling, root planing and surgery. In the conventional placement technique, the surface tissue topography is changed by the layer of set adhesive holding the fiber in place, and patients often explore this area with their tongues, resulting in premature loss of the fiber. This article offers an alternative fiber-placement technique that minimizes changes to the surface tissue and results in improved fiber retention.
