No. The maximum range of stretching with the gentle jaw is 54 mm. This is the maximum anyone should stretch their jaw on a consistent basis since the normal range of motion for people is 40 mm to 55 mm, according to some research, and 40 mm to 60 mm according to other research. Dr. Hirschinger never wants anyone to overstretch, which is why the largest gentle jaw has a maximum range of 54 mm. Beyond that, you can overstretch the ligaments, muscles, and retrodiscal tissues of the temporomandibular joint, and you can cause an open lock or subluxation of the jaw, which means you cannot close as depicted in the animation.
