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

Soft tissue management in bone augmentation is critical to ensuring the predictability of new bone formation. The flap elongation, by way of a periosteum releasing incision, determines an anatomical alteration of the existing soft tissue architecture. In particular, both the vestibule position and the mucogingival line are moved coronally. The correction of the vestibule position is usually performed by a partial flap preparation very close to the periosteum layer, reducing the overall supracrestal tissue volume. The presented technique defines a strategy to obtain flap elongation, potentially without the loss of the vestibule position. Clear anatomical reference points are introduced and described to render the technique predictable and repeatable.
