Metal Braces? Invisalign? Time? (Photo)

Hi, I am 35 years old male with 3 molar crowns. 1 extraction carried out 1 year ago at lower right molar, thinking to get a dental implant for that. This question is related to correction of canine teeth and alignment of all teeth. Should I go for metal braces or invisialign can work? How much time it may take (approximate) ? Which one woks best with crowns? Should I first go for implant or correction? Thanks for your replies.
