A satisfactory positioning of the dental implants is very important in the cosmetic and functional outcome in this treatment for edentulous. Insertion of an endosseous implant in the correct positioning requires sufficient bone volume. Therefore, bone-grafting procedures are becoming increasingly common, especially for the augmentation of horizontally deficient ridges.
Many patients have been treated with this technique of appositional Bone Graft Tunneled at our clinic since 2005. The method will be completed through the technical note of a surgical procedure involving a dental implant used for edentulous space rehabilitation in the jaws and the tunnel technique with an appositional bone graft, using the mandibular arch as the donor area.
The substitution of screws to stabilize the bone graft for the tunnel technique allowed the surgery to be performed in a shorter time. The advantages were as follows: the absence of complications associated with conventional titanium screws, the preservation of the integrity of the periosteum, and the fact that there was no need to remove the screws through relaxing incisions in the gingival mucosa before placing the implant.
The tunnel technique for onlay bone grafting is a simple and easy to perform technique, which is completed with less surgical time and at a lower cost and has presented highly predictable results and high success rates.
在无牙颌治疗中，牙种植体的满意定位对于美观和功能效果非常重要。将骨内种植体植入正确位置需要足够的骨量。因此，骨移植手术越来越普遍，尤其是用于水平骨量不足牙槽嵴的增量。
自2005年以来，我们诊所已使用这种贴附式隧道骨移植技术治疗了许多患者。该方法将通过一份手术技术说明来完成，该手术涉及用于颌骨无牙间隙修复的牙种植体以及使用下颌弓作为供区的贴附式骨移植隧道技术。
采用隧道技术用螺钉替代来稳定骨移植，使手术能在更短时间内完成。其优点如下：不存在与传统钛螺钉相关的并发症，保留了骨膜的完整性，并且在植入种植体之前无需通过牙龈黏膜的松弛切口取出螺钉。
覆盖式骨移植的隧道技术是一种简单易行的技术，手术时间更短、成本更低，且具有高度可预测的结果和高成功率。
