Patients with a Class III malocclusion generally present with a counterclockwise inclination of the occlusal plane, converging with Camper's line towards the front. This slope has an effect on mandibular movement (forward posture) and on chewing mechanisms in general. As dysfunctional mastication is likely to influence facial growth and inter-arch stability negatively, early orthopedic therapy of the occlusal unbalance concurrent with Class III malocclusion is justified. The aim of this article is to present a method of Class III treatment based on a correct re-orientation of the occlusal plane in order to achieve an optimal masticatory mechanism, essential for stability of early treatment outcomes.
III 类错颌患者通常表现为牙合平面逆时针倾斜，与坎贝尔线一起向前会聚。这种坡度会影响下颌运动（前伸位）和咀嚼机制。由于功能不良的咀嚼可能会对面部生长和上下颌弓的稳定性产生负面影响，因此，III 类错颌伴牙合不平衡的早期矫形治疗是合理的。本文的目的是介绍一种基于正确重定向牙合平面的 III 类治疗方法，以获得最佳的咀嚼机制，这对于早期治疗结果的稳定性至关重要。
