Sliding genioplasty, smoothing edges?

In larger sliding genioplasty movements there is going to be an inverted v-shaped notch that develops at the back end of the osteotomy along the lower edge of the jaw lien. This is an inevitable sequelae that occurs as the bone slides forward. Whether that causes an aesthetic issue (indent) depends on numerous factors the most relevant of which is the thickness of one's tissues and the size of the bony notch. Concerns about this bony irregularities can be addressed by placing contouring materials at the notch area.  

I have been performing sliding and multidimensional osseous genioplasties more than a decade ago, and to no one patient I had to do a touch up to smoothen edges; seems the nature of the mandibular jaw does this work instead of us surgeons in laps of 40-90 days, rounding and smoothening the contour. In other words, the surgeons perform the gross work and the nature the fine work, as simple and beneficial as it seems, and I know well by own surgical experience.Medical illustrations do not reflect the exact behaviour of real anatomy.
