title: The double split flap: a surgical approach for regenerative treatment of interproximal defects.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  This article describes the introduction of a modified flap design, the double split flap.
  
  
  CONCLUSIONS
  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.
