Figure 11. Pruzansky-Kaban Type IIa, illustrating the benefits of osteodistraction of the horizontal ramus. (a) Orthopantomogram prior to osteodistraction. Note the dental midlines are not aligned (blue arrows). The white arrow indicates the distance between the vertical ramus and the erupted last molar; (b) orthopantomogram immediately following osteodistraction. The dental midlines (blue arrows) are now aligned. The white arrow indicates the original and the red arrow represents the postdistraction distance (regenerate gain) between the ascending ramus and erupted last molar
