Through the guidance force of a 70 ° inclined plane during occlusion, the mandible is displaced from its previous position of far middle malocclusion, causing reconstruction of the jawbone and temporomandibular joint, thereby correcting the misalignment between the upper and lower jaws.

It also stimulates growth of the lower jaw for optimal alignment of the upper and lower teeth, as well as correcting protrusion or overjet and creating a better bite.
