摘要： A method for volume scanning of both hard tissues (126) and gingival tissues (122) of a patient is proposed. The method includes comprising the steps of using an impression (84) of a material visible in a volume scan, generating a volume scan in which hard tissue (126) is visible and said impression (84) is visible, and gingival tissue (122) being represented as the space between the visible hard tissue (126) and the visible impression (84). The volume scan includes a surgical site (162) to receive an ablation probe tip (108). The results of the step of generating a volume scan are provided for the purpose of manufacturing a custom surgical stent (110) having at least one surgical guide (112) for guiding placement of an ablation probe tip (108). The results comprise information representing said gingival tissue (126) and said hard tissue (126).

摘要： An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and colour photographs, are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their effect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called "morphing" type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.
