Many studies analyse the effectiveness of the Herbst device in the treatment of dentoskeletal Class II malocclusion due to mandibular retrusion. This fixed device was devised by Emil Herbst for Class II treatment using a bite jumping, i.e., a device that holds the jaw in a forced anterior position. Comparison of the results obtained in numerous studies is difficult because they are often not comparable and not congruent due to a number of variables that prevent standardization.
The purpose of the present study is to report some clinical-level considerations that may be important in order to obtain more predictable therapeutic outcomes. The simplified design of the Herbst device offers better patient comfort and easier cleanability but may show some disadvantages, such as less anchorage.
The device was evaluated in conjunction with the multi-bracket phase that preceded Herbst therapy and concluded after the device was removed. The therapy was performed in the absence of skeletal anchorage.
In our opinion, standardization of therapy according to precise protocols may positively affect the therapeutic outcomes by achieving faster occlusal stabilization, more proper neuro-muscular balance, less stress on anchor units, and shorter treatment time.
许多研究分析了Herbst矫治器在治疗因下颌后缩导致的牙颌面II类错合畸形中的有效性。这种固定矫治器由埃米尔·赫布斯特设计用于II类错合畸形的治疗，采用咬合跳跃，即一种将下颌保持在强制前伸位置的装置。由于许多变量阻碍了标准化，众多研究结果的比较很困难，因为它们往往不可比且不一致。
本研究的目的是报告一些临床层面的考量因素，这些因素对于获得更可预测的治疗结果可能很重要。Herbst矫治器的简化设计为患者提供了更好的舒适度且更易于清洁，但可能存在一些缺点，如支抗不足。
该矫治器与Herbst治疗前的多托槽阶段一起进行评估，并在矫治器拆除后结束。治疗在没有骨支抗的情况下进行。
我们认为，根据精确方案进行治疗标准化，通过实现更快的咬合稳定、更合适的神经肌肉平衡、对支抗单位的压力更小以及治疗时间更短，可能会对治疗结果产生积极影响。
