Will only a bsso add a few mm of chin height?

[one job away]

If you would move the maxilla and the mandible on the occlusion plane with a binax, then obviously you would get a higher chin. But what if the upper teeth(maxilla) stay the same and you Only do a bsso. If you bit down will you have some more chinheight ? Since the mandible moved Alongside the occlusional plane?
