The double split flap: a surgical approach for regenerative treatment of interproximal defects

Aims and Background: Primary wound closure has been advocated to be indispensable for a successful outcome of guided tissue regeneration‐procedures. Yet narrow inter‐proximal spaces often lack sufficient tissue quantity in order to facilitate a tension free re‐adaptation of periodontal flaps. In order to maintain an uneventful healing process, the concept of layer‐wise wound closure is applied to periodontal surgery. Material and Method: This article describes the introduction of a modified flap design, the double split flap. Results and Conclusion: By preparation of a second, internal flap and a wound in a layer‐wise fashion, it is assumed that primary healing will be more predictable to achieve.
