title: The soft tissue wall technique for the regenerative treatment of non-contained infrabony defects: a case series.
abstract: The ability to stabilize the blood clot is crucial in achieving predictable periodontal regeneration in infrabony defects. Unfortunately, micromovements may cause degradation of the clot-root interface and result in suboptimal wound healing. Current surgical and suturing techniques are aimed at reducing flap micromovement because flap management is one of the main factors influencing the stability of the clot. The aim of this paper is to describe the use of the soft tissue wall technique to enhance periodontal tissue regeneration outcomes of challenging non-contained infrabony defects. Nine one-wall infrabony defects were treated with a combination of a papilla preservation technique and a coronally advanced flap. Enamel matrix derivative was delivered to the defect, but no bone grafting materials or membranes were employed. Mean 1-year probing depth reduction was 6.3 ± 2.0 mm (P < .001) and mean clinical attachment gain was 7.1 ± 1.0 mm (P < .001). All treated sites showed a mean reduction of exposed root surface equal to 1.0 ± 0.4 mm (P = .05). The results suggest the possibility of improving the regenerative potential of a one-wall infrabony defect by the creation of a stable soft tissue wall while also enhancing the esthetic outcome of the surgical procedure. Further studies with a larger number of patients are needed to support these preliminary data.
