Will Crowded Teeth Need Pulling Before Invisalign?

With no disrespect to previous answers, I am unable to determine whether you require extractions from this photo you have taken.  There are many considerations other than crowding that determine the need for tooth removal including profile and periodontal health.  This photo alone is not diagnostic, which is why you require a complete orthodontic diagnosis including x-rays, photos, and an examination before coming up with a treatment plan.

With Invisalign, some dental expansion is possible, but it is not the type of appliance used that determines whether extractions are required or not.  If you needed extractions, you would require them with braces or aligners.

Looking at your photos I feel expansion with orthodontic treatment could eliminate the crowding without the need to remove teeth. In this situation, I will many times start a case non-extraction and evaluate in approximately 4 to 6 months whether to extact teeth or not. I would, however, highly recommend fixed appliances rather than invisalign to treat your case. There are significant angulations issues with your teeth and to properly parallel the roots is very difficult to accomplish without fixed appliances(braces). Without properly paralleling the roots in the bone during treatment will only result in relapse after your braces are removed.
