This project is combining multidisciplinary expertise in engineering and dentistry to create a 3D surface model of the human jaw from optical imaging. The instrumentation system for generating the model is intended to be simple and inexpensive. This model will change a number of dental practices to be more precise and less time demanding, and will lead to reduction in cost. Using a small-size CCD camera, a sequence of calibrated 2D images is generated which spans the jaw. Geometrical computer vision methodologies are employed to extract 3D information from the sequence of images, which are then registered together to construct the jaw. Characteristics of the jaw are exploited in the registration. The 3D surface model is in itself very useful for basic studies of tooth alignments and in a number of orthodontic practices. However, when root and bone information are fused to the surface model, a comprehensive 3D model is obtained which will render great benefits to dentistry. Even partial information about the bone and root structure will be leveraged in the modeling by incorporating modern approaches of geometric modeling. The jaw model will form the basis for biomechanical studies for proper description of tooth movement, which will be very useful for alignments, implants and numerous craniofacial procedures. The model will also be an enormous tool in the teaching and training of future dentists. A number of dental students will be included in evaluating the model in various stages of developments, and a small set of volunteers will participate in a study to validate the resulting models.

该项目结合了工程学和牙科学的多学科专业知识，通过光学成像创建人类颌骨的3D表面模型。用于生成模型的仪器系统旨在简单且廉价。这种模式将改变许多牙科实践，使其更精确，时间要求更少，并将导致成本降低。使用一个小尺寸的CCD摄像机，校准的二维图像序列生成的跨颌。采用几何计算机视觉方法从图像序列中提取3D信息，然后将其配准在一起以构建颌。 在配准中利用了钳口的特征。3D表面模型本身对于牙齿排列的基础研究和许多正畸实践非常有用。然而，当牙根和骨骼信息融合到表面模型时，获得了全面的3D模型，这将为牙科带来很大的好处。通过结合现代的几何建模方法，即使是关于骨骼和牙根结构的部分信息也将在建模中被利用。 颌骨模型将形成生物力学研究的基础，以正确描述牙齿移动，这将是非常有用的对齐，种植和许多颅面程序。该模型也将成为未来牙医教学和培训的重要工具。 一些牙科学生将被包括在评估模型的各个阶段的发展，和一小群志愿者将参加一项研究，以验证所产生的模型。
