摘要： A method for automatic, or semi-automatic, planning of dental treatment for a patient comprises: (a) obtaining data about an area which is to be treated and data about a face of a patient; (b) performing a computer-assisted analysis of the data to determine properties of at least the face of the patient; (c) creating a modified tooth set-up using a set of stored rules which make use of the determined facial properties. A three-dimensional representation simulates the appearance of the modified tooth set-up and the patient's face surrounding the treatment area. The method also determines properties of existing teeth and creates a modified tooth set-up which is also based on the existing teeth of the patient. The method can be implemented as software running on a workstation.

摘要： A patient's dentition is analysed to determine an orthodontic treatment plan by simulating an intervention in advance. 3D imaging techniques and computer technology are used to simulate and predict tooth movement as a function of the chosen treatment, i.e. a specific orthodontic appliance. In this way treatment options can be compared and the most optimal (shortest treatment time, lowest forces . . . ) treatment for each individual patient can be selected. Sub-steps of the tooth movement are not predefined but computed based on a simulation of orthodontic elements and wire as they would be used in the orthodontic treatment of the patient. This means that the sub-steps are calculated based on the relationship between the applied loads and the tooth movement; only one of both parameters can be chosen freely. Thus, either the tooth load is specified and applied in order to calculate the resulting tooth movement or vice versa the tooth movement is specified and applied in order to calculate the tooth load that should be applied. Moreover, the current invention allows predicting the time at which brackets and/or archwire should be changed, and comparing different treatment options with respect to tooth loading and duration.
摘要翻译： 对患者的牙列进行分析，以通过预先模拟干预来确定正畸治疗计划。 3D成像技术和计算机技术用于模拟和预测作为所选择的治疗，即特定的矫正器具的功能的牙齿运动。 以这种方式，可以比较治疗选择，并且可以选择每个患者的最佳治疗（最短治疗时间，最低的力量...）治疗。 牙齿运动的子步骤不是预先确定的，而是基于在正畸治疗患者时使用的正畸元件和线的模拟来计算。 这意味着子步骤是根据所施加的载荷与牙齿运动之间的关系来计算的; 只有两个参数中的一个可以自由选择。 因此，为了计算所产生的牙齿运动，指定和施加牙齿负荷，或者反之亦然，指定和施加牙齿运动，以计算应该施加的牙齿负荷。 此外，本发明允许预测托架和/或弓丝应当改变的时间，并且比较不同的治疗方案相对于牙齿的负荷和持续时间。

摘要： A three-dimensional computer model of the patient's tooth, including the pulp chamber and root canals, is created by combining at least one grey value image of the tooth and/or surface information about at least part of the intra-orally visible part of the tooth with a statistical, parameterized shape model of each tooth type (upper or lower incisors, canines, pre-molars, molars) as the patient's tooth to be treated. This allows for planning and/or simulation of one or more root canal treatments on the computer model of the patient's tooth and that the dentist or dental specialist is given qualitative and/or quantitative information by the system in order to aid in adequately analyzing the risks related to performing the root canal treatment with the proposed or user-selected endodontic tools.

摘要： Use of computer technology for image-assisted risk assessment/evaluation of proposed dental treatments is described, in particular a method and apparatus for determining the impact of a proposed dental modification on the temporomandibular joint(s), e.g. to obtain information relating to that impact. Use of a virtual articulator is described to determine the impact of a proposed dental modification on the temporomandibular joint(s). This dental modification includes, but is not limited to, the replacement of one or more teeth by artificial teeth, the replacement of one or more parts of a tooth by a prosthetic reconstruction such as a dental crown or veneer, the rearrangement of one or more existing teeth (orthodontic treatment), the distraction of one or both jaws in order to reposition the teeth (orthognatic treatment) and/or modifications of the occlusal surfaces of the teeth.
