Try this:
Code:
line='aaaaaaa${important}xxxxxxxx${important2}ooooooo${importantstring3}'
IFS=\$ read -a _a <<< "$line" 
_regex='(\{[^}]+})'
for _e in "${_a[@]}"; do
  [[ $_e =~ $_regex ]] &&
    _n+=( "\$${BASH_REMATCH[0]}" )
done
# your matches are in the _n array

For example:

Code:
$ line='aaaaaaa${important}xxxxxxxx${important2}ooooooo${importantstring3}'
_regex='(\{[^}]+})'
$ IFS=\$ read -a _a <<< "$line"
$ _regex='(\{[^}]+})'
$ for _e in "${_a[@]}"; do
>   [[ $_e =~ $_regex ]] &&
>     _n+=( "\$${BASH_REMATCH[0]}" )
> done
# your matches are in the _n array:
$ # your matches are in the _n array:
$ declare -p _n
declare -a _n='([0]="\${important}" [1]="\${important2}" [2]="\${importantstring3}")'
