About

Minimally invasive procedures with the tunnel technique have been suggested to decrease patient post-operative discomfort and morbidity in oral bone regeneration. In the ridge augmentation tunnel technique, crestal incision and the release of the connective tissue are avoided in order to enhance the blood supply of the flap. This approach preserves the blood circulation and does not damage the periosteum The purpose of this study is to evaluate the clinical outcome of a minimally invasive technique for maxillofacial horizontal bone augmentation .

Full description

Several techniques have been introduced to minimize the invasiveness involved in oral bone regeneration, to prevent the coronal advancement of the flap, which in turn reduces postoperative discomfort, swelling, complications, and mobility.

The tunnel technique involves making a vertical incision to access the bone defect and inserting the grafts. The significant benefit of this approach is that it may be closed without the need for periosteal incisions. Several tunnel techniques have been described in the literature using various biomaterials including bovine bone, synthetic bone, bovine bone block, allograft block bone, hidroxiapatite. This clinical study assesses the efficiency of a minimally invasive surgical technique for horizontal ridge augmentation using Biphasic Calcium Phosphate and Acellular Dermal Matrix.

This minimally invasive procedure aims to increase the horizontal volume of the edentulous ridge in both its bone component (through the use of Biphasic Calcium Phosphate) and its mucosal component (through the use of Acellular Dermal Matrix). Compared to other traditional techniques, this procedure, performed through a tunnel approach, would significantly reduce the invasiveness of the treatment.
