You can apply to extend her status while she is in Canada if she wants to stay longer. However this won't extent the actual super visa. The extension will only allow her to remain in Canada longer for this specific visit.

The main way for parents to get PR is through the parent / grandparent family sponsorship program. You will first need to meet the minimum income requirements to qualify to sponsor her. You will then need to enter the lottery and hope you are selected as a sponsor. The lottery is generally held once a year. Those selected can then sponsor their parents for PR. We don't know when the lottery is going to open this year.
