Orthodontic appliances should be designed to satisfy goals for denture, patient, and doctor. An appliance that is able to achieve these goals more closely approaches the ideal treatment system. Analysis of appliances of the Begg and straight wire types indicates that each treatment system has significant advantages and that the advantages of one system frequently are the disadvantages of the other. A technique that uses both the tipping principles of Begg and the bodily movement principles of the straight wire type of appliance has been designed and clinically evaluated. The unique capability of the combined treatment approach is in the mechanical design of the new combination four-stage bracket. A description of the appliance and the technique, as well as a clinical case presentation, is included in this article.
正畸矫治器的设计应满足义齿、患者和医生的目标。能够更接近实现这些目标的矫治器更接近理想的治疗系统。对Begg矫治器和直丝弓矫治器的分析表明，每种治疗系统都有显著的优点，而且一种系统的优点往往是另一种系统的缺点。一种结合了Begg矫治器的倾斜原理和直丝弓矫治器整体移动原理的技术已经设计出来并进行了临床评估。联合治疗方法的独特之处在于新型组合式四阶段托槽的机械设计。本文包括了该矫治器和技术的描述以及一个临床病例展示。
