Zoe,
Pav is correct in mentioning that there might be one or two other problems that could need sorting out first, but this kind of case certainly can be treated with an Inman Aligner.
I normally treat a case like this with a combination of an Inman Aligner (which will do most of the alignment) and one or two clear positioners to tweak the canine teeth afterwards.
Again, factors such as your bite position which can influence the degree of tooth movement possible,
cannot be assessed from photographs, so really you do need to get a consultation first.
Regards.
