Please Tell Me What I Can Do About a Step off Occuring in a Genioplasty??

I had this procedure done almost 2 months now and it resulted in this big U-shaped chin where it looks detached from my face and it does not form a uniform sweep with my jawline. Can I go to a PS to get fillers done on the gaps? I asked my surgeon who is a maxillary surgeon about it and he said there will be a bony remodeling to occur within the next 6 months and I asked if I still had swelling left and he said no. What I am most concerned about is the fact that my chin has this bulge.
