Chin implant help - I underwent chin implant by intraoral method 6 weeks ago.

I still feel numb at my chin and lower bottom lip. It is better compared to the first two weeks but ever since then, it hasn't improved. It feels weird to talk and smile. I also feel that it looks too strong for my liking. When will I see final results? Will it take months for sensation to come back and swell to go away? Is there a way to tell if nerves are damaged, possibly through X-ray or CT scan?
