Why did patients apply to this trial?

I reached out because I'm dissatisfied with my current denture situation and am eager to explore alternative options in the hopes of making a life-changing improvement.
PatientReceived 1 prior treatment
I have been unable to afford dental implants I had to have my teeth removed due to years of griding my teeth eating ice etc. I am 57 and my lower jaw is starting to sag which give the appearance of someone much old. I prided myself all my life of not looking my age, well that has not been the case lately. PLEASE I need help.
PatientReceived no prior treatments
