Mechanical tension and bone remodeling, the holy grail of controlling bone growth at young age.

yeah sry bro doesnt work that way first hitting it doesnt give the ideal bending movemnt which what leads to perostieal appostion but perostieal appostion in long bones have shown insignificant diffrence its sub-mm growth IMAGINE in carnio facial bones and they way you bonesmash isnt ideal but assuming you do cyclic pressure based bonesmashing you could gain a mm after YEARS OF IT but its completely theorictacl and 100% take way more time will make a thread on that some time
but great effort and thread
I would disagree here, when done correctly, the loadings put on your bone WILL engage bone remodeling and then bone growth in that specific area, WHEN DONE CORRECTLY, as show here.

Did you read everything I wrote? Or just assume I followed some tiktok trend?
You said the gain will be a few millimeters after multiple years, which is already not true, but even if it was, it's common knowledge that a few millimeters on facial bones is an immense difference.
