摘要
针对传统种植方法容易产生植入位置不正和虚拟设计手术难转移问题,文章设计一种基于VTK可视化类库实现新型的CT图像三维虚拟牙种植导航系统;通过对能提供详细软组织,植入区牙颌骨及相邻解剖结构的CT数据进行预处理,三维重建,三维切割与测量;医生能在此系统中参考种植体、邻牙及相关牙骨结构,进行虚拟种植体植入位置、尺寸、角度的设计并通过配准融合的方法生成种植导航导板;实验结果表明:该系统能真实直观地再现牙颌骨全貌,准确地把虚拟手术转化到实际手术中,提高了牙种植修复效果。
In view of the traditional planting methods are prone to implant malposition and virtual design operation difficult to transfer problems, this paper designs a VTK visualization class library to realize new 3D virtual tooth planting navigation system based on CT image. Then, the doctor can refer to implant in the system and adjacent tooth and tooth structure, carries on the virtual implants implanted position, size, Angle of design. The generation method of registration and fusion implant guide. The experimental results show that the system can truly reproduced picture of teeth and jaws, accurately the virtual operation into actual operation, improve the effect of dental implant.
