摘　　要：本文基于计算机辅助技术提出了一种利用CT数据和牙石膏模型数据系统化的口腔种植导板设计方法。通过分析患者的CT数据,利用图像处理技术规划种植区域,并对于一个指定的种植区域,提出解剖学意义上的种植体合理分配方法。该方法在考虑生物力学原理以及美观和功能的前提下,能够充分利用患者可用的骨质和骨量,确定种植轴线的最佳位置。然后将CT模型和牙石膏模型配准,实现种植规划向患者口腔的转移。最后以一名患者为试验对象,完成了整个种植导板设计过程,从而验证了本方法的正确性和可行性,这对于提高种植手术的质量与精度具有重要意义。The present paper was conducted to a systematic method of surgical guide for dental implant based on computer-aided technology through CT data and dental-cast data.By analyzing the patient＇s CT data,the implant region was planned using image processing techniques.For the specified implant region,the computer-aided method for the rational allocation of dental implant was addressed in a sense of anatomy.With biomechanical principles as well as aesthetical and functional requirements as preconditions,this method can make full use of bone quantity and quality to produce the optimum implantation axis.The transferring of implant planning to the patient was then realized by registration between CT models and dental-cast models.A case research explained the whole process of the surgical guide.The results validated the correctness and feasibility of this method,which has a great significance to enhance the quality and accuracy of implant surgery.
