简要总结
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 .
详细描述
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.

结局指标
主要结局
Evaluation of the achievement of an adequate thickness of the alveolar ridge ridge
时间窗: 5 months
Digital intraoral casts will be superimposed to value the gained thickness of the ridge. The assessment of volume increase in the alveolar ridge will be observed within the implant planning software by measuring the variation in the width of the edentulous ridge by matching three scans. The scans will be conducted at baseline (T0), five months after ridge augmentation (T1), and two months after implant insertion (T2). The matching will be performed using corresponding pairs of regions. The thickness of the alveolar ridges on the same cross-section at the level of the implants inserted will be measured in mm using the "distance" tool.
次要结局
- Histological analysis of newly formed tissues.(5 months)
