Do i have wider cheekbones for straining the jaw?

Im 20 years old and i have bruxism since a couple of years.I noticed that my cheekbone became wider and bigger this last year and i recently read this:"In the skull there’s this thing called the zygomatic arch,which is behind the eyes,and your jaw fits in there,and if you have a really big zygomatic arch,then that means that a lot of muscle is in there"my question is:could bruxism have done this ?By the fact of straining the jaw,the zygomatic bone get wider for the amount of aumented muscle?
