Midsagittal Plane

The midsagittal (horizontal) plane is positioned perpendicular or at a right angle to the floor and centered right to left. Many machines display a vertical alignment light or mirror to adjust the alignment of the midsagittal plane so that the right and left sides of dental arches are equally displayed.
