    摘要: A model of the teeth in a patient's mouth and a prescription of desired positionings of such teeth are provided by the patient's orthodontist. The contour of the teeth in the patient's mouth is determined, preferably digitally, from the model. Calculations, preferably digital, on the contour and the desired positionings of the patient's teeth are then made to determine the geometry (e.g. grooves) to be provided in brackets for receiving an arch wire to form an orthodontic brace. Such geometry is intended to provide for the disposition of the arched wire on the brackets in a progressive curvature in a horizontal plane and a substantially linear configuration in a vertical plane. The geometry of the brackets is altered (e.g. by cutting grooves in the brackets at individual positions and angles and with particular depths) in accordance with such calculations of the bracket geometry. The brackets may be disposed on the model of the patient's teeth at positions dependent upon such calculations. A mold may be formed of the model of the patient's teeth and the brackets on such teeth. The model and the mold may be shipped to the orthodontist with written instructions for the disposition of the brace on the patient's teeth. Alternatively, an information sheet may be prepared, after the calculation of the bracket geometry, to specify the placement of the brackets on the patient's teeth and the disposition of the arch wire on such brackets. The brackets and the information sheet are sent to the orthodontist.

    摘要翻译: 患者口腔中的牙齿模型和这种牙齿所需位置的处方由病人的牙齿矫正器提供。 确定患者口腔中牙齿的轮廓,最好是数字地从模型中确定。 然后,对轮廓和患者牙齿的期望位置进行计算,优选数字化,以确定要在托架中提供的几何形状(例如凹槽),用于接收弓形线以形成正畸支架。 这种几何形状旨在提供弓形线在支架上的布置,其在水平平面中呈渐进曲率,并且在垂直平面中具有基本上线性的构造。 根据支架几何形状的这种计算,支架的几何形状被改变(例如通过在各个位置和角度以及特定深度处切割支架中的凹槽)。 支架可以根据这种计算的位置设置在患者牙齿的模型上。 模具可以由患者牙齿的模型和这些牙齿上的支架形成。 模型和模具可能会以正确的方式运送到正牙医生,以便将患者牙齿上的支架放置在书面上。 或者,可以在计算支架几何形状之后准备信息表,以指定托架在患者牙齿上的位置以及将弓线布置在该支架上。 括号和信息表发送给正牙医生。

    摘要: A device for dispensing elastomeric orthodontic appliances. The device has a mounting section having a rigid support structure and an outer layer. The outer layer has integrally formed therewith a plurality of orthodontic appliances detachably connected thereto. The outer layer and appliances are made of a material having a stiffness substantially less than that of the support structure. The device also has a finger gripping section attached at one end of the mounting section and preferably made integral with the rigid support structure.
