Modified Coronal Advanced Flap in Bone Augmentation Procedure. Case series and Technical Notes

The soft tissue management in bone augmentation is critical to ensure the predictability of new bone formation. The flap elongation, by periosteum releasing incision, determines an anatomical alteration of the existing soft tissue architecture. In particular the vestibule position as well as the muco-gingival line are moved coronally. The correction of the vestibule position is usually performed by a partial flap preparation very closed to the periosteum layer reducing the overall supra-crestal tissue volume. The presented technique defines the strategy to obtain a flap elongation potentially without the loss of the vestibule position. Clear anatomical reference points are introduced and described to render the technique replaceable and predictable.
