摘　　要：目的设计制作一种种植手术外科模板,用以解决种植体植入位置、方向和深度准确性的问题。方法本研究借助螺旋CT和计算机图像处理软件,将拟种植区的牙槽骨和基骨的形态准确地转移到石膏模型断面上,然后在石膏模型"牙槽骨和基骨"的范围内设计种植体植入的位置、方向和深度并制作定位模板,应用该模板在1对上颌骨和下颌骨体外模型上共制备27个种植窝,并应用配对t检验比较骨骼和石膏模型种植体的定位情况。结果采用配对t检验比较骨骼和石膏模型种植体定位情况,数据均达到了理想的精确度。结论本模板定位、定向准确,可以最有效地利用植入区的骨量,从而扩大了种植修复的适应证,可有效地避免种植手术的失败。Objective To fabricate a surgical template to solve the problem of the precise positioning and orientation in the process of dental implant. Methods Following a comprehensive oral examination and precise measurement by CT and Photoshop,the shape of the basal alveolar bone of the planed implant area was trans-ferred onto the plaster sectional model. Then the site and orientation of the fixtures could be designed in the range of dentoalveolar and matrix bone and positioning template could be made. With this template,27 implant caves of one pair skeletal and mandibular bone were prepared. Results A satisfied result was achieved by using t paired test. This template could enhance the accuracy of placement in an efficient way to achieve predictable esthetic results. Conclusion The underlying basal alveolar bone can be used most effectively with this template. Also,it can extend the precision of dental implantation. This method showed better clinical treatment effects and it is suitable for widespread use in clinical practice.
