Extensive loss of alveolar bone and teeth in the anterior mandible presents a complex problem for reconstruction. Numerous augmentation techniques are currently in use to create sufficient bone volume for reliable placement of endosseous implants in the case of severely resorbed mandibles. The aim of this report is to assess the efficacy of the piezoelectric sandwich osteotomy for vertical augmentation in the atrophic segment of anterior mandible through clinical and histologic studies. A complete osteotomized segment was made, using the piezoelectric saw, to make a segmented bone in the atrophic edentulous area and the mobile segment was elevated by 10-mm high vertically. Interpositional mineral allograft materials were inserted in the space between the basal bone and the segmented bone. A bone biopsy was performed on the augmented bone region and 3 dental implants were placed simultaneously 6 months later. About 10 mm of vertical gain was achieved by the sandwich technique. Histologic analysis presents new bone formation without inflammatory or foreign body reactions.
下颌前部牙槽骨和牙齿的大量缺失给重建带来了复杂的问题。目前有多种增量技术用于在严重吸收的下颌骨病例中创造足够的骨量，以可靠地植入骨内种植体。本报告的目的是通过临床和组织学研究评估压电夹心截骨术在前部下颌骨萎缩节段进行垂直增量的疗效。使用压电锯制作一个完整的截骨节段，在萎缩无牙区制作一个分段骨，可移动节段垂直抬高10毫米。将异体矿物质移植材料植入基骨和分段骨之间的间隙。在增量骨区域进行骨活检，并在6个月后同时植入3颗牙种植体。通过夹心技术实现了约10毫米的垂直增益。组织学分析显示有新骨形成，无炎症或异物反应。
