It is possible to correct all of the above issues with Invisalign, depending on the severity of each individual issue. I recommend that you make an appointment for consultation with a board-certified orthodontist who has plenty of experience with Invisalign so that he or she can determine if you are a good candidate for this kind of treatment.

It may be possible for your doctor to do some wire bending or bracket repositioning to help align your incisors. Speak with your Orthodontist. 

It is recommended that you aim for at least 20 hours per day of wear but optimal wear would be 22 hours or greater per day. 

IPR can be very effective at reducing the appearance of black triangles, however, it must be done carefully and not aggressively as to avoid tooth sensitivity. 

Although early termination is not usually recommended unless there are other dental/health concerns that take precedence, the closer you are to being done with orthodontic treatment, the less problematic it will be to have your braces removed early. For instance, if you are very close to finishing treatment, it may be possible to finish your case with a course of Invisalign Express treatment, which may be lower maintenance for you than braces.
