Conventional Begg technique is efficacious for alignment, overbite reduction, and anchorage conservation, but it has a number of deficiencies. Biomechanical systems should be determined by the characteristics of each individual malocclusion, not by habitual application of the same recipe to every patient. Check elastics can increase the bite-opening potency of the appliance, thus permitting control of root movement at any stage. Ribbon arch wires can provide torque control for either bolstering or expending anchorage. Extraoral traction can provide anchorage, control of orientation of the dentition within the face, and simplify and/or shorten treatment in some cases.
传统的Begg技术在牙齿排齐、覆合减小和支抗保持方面是有效的，但它也有一些不足之处。生物力学系统应该根据每个个体错颌畸形的特点来确定，而不是对每个患者都习惯性地应用相同的方法。检查性弹力牵引可以增加矫治器打开咬合的能力，从而在任何阶段都能控制牙根移动。带状弓丝可以提供扭矩控制，用于增强或消耗支抗。口外牵引可以提供支抗，控制牙列在面部的方向，并且在某些情况下可以简化和/或缩短治疗时间。
