Can permanent retainers cause an overbite after braces? (photos)

I had upper braces for 3 years, then both braces for 2 years. I wear permanent retainer now, I notice that I have a little bit overbite on 4 of upper front tooth. Is it possible because of the permanent retainer placement mistake?, It doesn't look like this after the 3 years upper braces only treatment and when I use braces. Is there anything I can do to make it straight again without having another braces treatment?
