I Have Used Radiesse August 2010, is It Safe to Use Permanent Fillers Next August?

Hi, I used Radiesse last August, August the 2nd to be exact. I've been feeling a bit disappointed with the results of the procedure since my doctor only did one thing right and left several things that I pointed out wrong. And I was hoping that I could get a permanent filler, but I was wondering when would be a safe time to use the permanent filler if my Radiesse injections were administered last year? The doctor said the effects would last for 6/8 months or a year at most
