    • An indirect bonding apparatus for orthodontic bonding procedures includes a tray having inner wall sections defining a channel for receiving the patient's dental arch. A number of orthodontic appliances are detachably connected to the tray along the channel, and each appliance includes a base for bonding the appliance to the tooth. The wall sections include at least one groove extending along the base of at least one appliance in order to provide a space between the wall sections and the patient's tooth structure when the tray is received on the patient's dental arch. The space hinders the flow of oral fluids such as saliva in directions toward the base in order to help ensure that the fluids do not adversely affect the strength of the resulting adhesive bond between the appliance and the tooth.
    • 用于正畸粘合方法的间接粘合装置包括具有限定用于接收患者牙弓的通道的内壁部分的托盘。 许多正牙器具沿着通道可拆卸地连接到托盘,并且每个器具包括用于将器具粘合到牙齿上的基座。 壁部分包括沿着至少一个器具的基部延伸的至少一个凹槽,以便当托盘被容纳在患者的牙弓上时,在壁部分和患者的牙齿结构之间提供空间。 该空间阻碍口腔液体如唾液在朝向底部的方向上的流动,以帮助确保流体不会不利地影响所产生的器具和牙齿之间的粘合剂粘结的强度。

    • The present invention provides digitally driven methods to conveniently and efficiently monitor and evaluate the positions of a patient's teeth during the course of orthodontic treatment. In an exemplary embodiment, an initial set of 3D digital data representing a patient's dental structure is provided by means of an X-ray radiograph and/or an intraoral scan. Then during the course of treatment, a reduced image representing part of the dental structure may be quickly provided using a bite plate or a low resolution intraoral scan. A three-dimensional (3D) image of the full dental structure is subsequently rendered or ‘reconstructed’ by registering elements of the initial image with corresponding elements of the reduced image. By reconstructing the dental structure from the reduced image, the treating professional can provide a precise, manipulable 3D image of the patient's complete dental structure for diagnostic and treatment planning purposes. Other aspects include methods of using these data to compare actual and target teeth positions to evaluate the progress of treatment and suggest revisions to the specification of an orthodontic appliance.
    • 本发明提供数字驱动的方法,以便在矫正治疗过程中方便且有效地监测和评估患者牙齿的位置。 在示例性实施例中,通过X射线照片和/或口内扫描提供表示患者牙科结构的初始的3D数字数据集。 然后在治疗过程中,可以使用咬合板或低分辨率口内扫描快速提供代表牙科结构部分的缩小图像。 随后通过将初始图像的元素注册到缩小图像的相应元素来再现或“重构”完整牙科结构的三维(3D)图像。 通过从缩小图像重建牙科结构,治疗专业人员可以提供患者完整牙科结构的精确可操纵的3D图像,用于诊断和治疗计划的目的。 其他方面包括使用这些数据比较实际和目标牙齿位置以评估治疗进展的方法,并建议修订矫形器具的规范。
