so have you thought of the flex strength of the pmma at about 120mpa flex strength compared to the average biting force on implants at about 450 -600 mpa how long do you think it will last .even on a bar? i know someone will talk about the one thats seven years old thats been fine but the other 99 out of 100 that break they dont talk about. I would like people to explain to me how they beat material science its always very interesting.
