I have 2 cephs that were taken during the same month but they actually look different. In one, my lips are relaxed (no strain) - in the other I have them closed fully (with some strain) and so my upper lip area looks more vertical and longer.
Which is the "correct" lip posture when having cephs done?
Should you be showing strain? Or would this be misleading when it comes to soft/hard tissue relationships?
