A method for the three-dimensional reconstruction of CT-image data permits manufacturing of natural size anatomical models thus enabling preoperative measurements of relevant parameters (length, areas, and volumes). The methods described allow for new perspectives in preoperative planning of dental implants, particularly for the maxillary problem area. The use of 3D image data for manufacturing individual alloplastic implants simplifies the exact reconstruction of symmetrical bone structures, which up to now was impossible to achieve with conventional methods. Applications in the fields of orthodontic surgery and in neurological surgery are suggested. Refinement of available techniques is possible by means of additional segmentation of soft tissues, and by implementation of more sophisticated software for better visualisation and smoothly shaped surfaces. Future applications may even include aesthetic surgery.
一种用于CT图像数据三维重建的方法能够制造自然尺寸的解剖模型，从而实现术前对相关参数（长度、面积和体积）的测量。所描述的方法为牙种植体的术前规划带来了新的视角，特别是对于上颌问题区域。使用三维图像数据制造个性化的异体植入物简化了对称骨结构的精确重建，而这是传统方法至今无法实现的。文中还提出了在正畸外科和神经外科领域的应用。通过对软组织进行额外分割以及采用更先进的软件以实现更好的可视化和平滑表面形状，可以对现有技术进行改进。未来的应用甚至可能包括美容手术。
