The alveolar structure in the anterior single tooth missing area which has been resorbed, complicates the implant placement procedure . In order to recover the hard and soft tissue, it is aimed to graft the defected area and perform immediate prosthetic restoration with implant placement simultaneously . In the repair of the alveolar defect, minimal flap elevation makes it difficult to place the membrane and inhibiton of the contact of the graft material, placed between the membrane and the crest, with connective tissue in the apical region cannot be controlled .
With this novel technique, the membrane which has been turned into a square box creates a stopper between the graft and the soft tissue in the apical region. In addition, the rigid structure of the “box membrane” provides a space in augmentation area acting as a tent. Thus, grafting procedure can be done in a controlled manner and graft resorption can be reduced by preventing flap pressure on the graft material.
In the area where the implant placement is planned, crestal incision which is palatially positioned is extended to a distance of 2mm from adjacent papilla’s and combined with short vertical incisions. After dental implant is placed in the existing alveolar bone, flap is released using tunnel method gently. The barrier membrane is cut into 3 equal parts as shown in the (Figure 1). The outer parts are folded and turned inside, then closed on the middle part, so the membrane turned into a box corner. Overlapping parts are fixed with a resorbable suture. The part of the barrier membrane formed as a box corner will remain in the apical of the flap, and the concave part is placed in the region with the alveolar crest facing . The space between the barrier membrane and the crest is filled with particulate graft material. The flap is sutured by placing temporary restoration or healing cap on the implant (Figure 2).
In the single anterior tooth loss regions, double-stage surgery
is frequently performed to repair alveolar crest resorption
and the total healing time is extended . In addition, during
augmentation procedure, a wide flap is releasing in order to place
the biomaterials that are intended to act as tent, this causes the
recession of the adjacent gingiva and increasing the post-op pain
and edema .
With this new method, resorbed alveolar crests can be repaired
with a minimally invasive approach, and fixed restorations can
be performed immediately, therefore this approach enables the
recovery of hard and soft tissues.
