The improperiety of the location of implants would cause many difficulties to prosthetic procedure. The function, appearance and long-term health of implant denture would then be effected. Dental stents were used to resolve the above problems for 30 cases of implant denture involved 74 implants in present study. A radiographic stent with given diameter sphere can be used to eliminate distortion and determine the bone quantity. A surgical stent can express the prosthetic plan to surgeons during operation directly in the mouths of patients. It is very helpful to the surgeons to take account of both the condition of jaw bone and the future denture making. Holes, tunnels and windows on surgical stents can be used as the guidances of drilling positions and directions. The surgical stents may also be a useful reference to surgeons to make bone graft, do some changes in surgical plan and even cancel the implant denture therapy when the situation of jaw bone significantly differ from what the expectancy.
种植体位置不当会给修复过程带来诸多困难，进而影响种植义齿的功能、外观及长期健康状况。在本研究中，采用牙用支架为30例涉及74颗种植体的种植义齿解决上述问题。带有特定直径球体的放射学支架可用于消除变形并确定骨量。手术支架能在手术过程中直接在患者口腔内向外科医生展示修复计划，这对于外科医生兼顾颌骨情况和未来义齿制作非常有帮助。手术支架上的孔、通道和窗口可用作钻孔位置和方向的引导。当颌骨情况与预期明显不同时，手术支架对外科医生进行骨移植、改变手术计划甚至取消种植义齿治疗也可能是一个有用的参考。
