Should I see dentist or orthodontist for Clear Correct?

I've already paid for the treatment and had my impressions taken, the dentist hasn't received the trays yet though. After doing some Googling (a little late) I keep reading that an orthodontist is preferred as opposed to seeing a dentist as they are more qualified. Now I'm worried that I won't achieve the results I was hoping for because I'm going through a dentist. Is there really a substantial difference in the outcome?
