I am getting a 6 unit front bridge (ceramic)done. I have some issues with the temporary. Can these be fixed in the permanent?

The temporary bridge is just temporary.  They are just meant to cover the space without making you look weird for not having teeth there.  I usually try to make my temp pretty cosmetic, but many dentists do not, and this is okay.  The important thing to know is that you should ask the dentist to let you see the permanent bridge in your mouth when he tries it in at your next appointment.  This will let you see if there is anything that you do not agree with or would like adjusted, prior to its permanent placement in your mouth.  I hope this helps.  Feel free to click to save my name below, in case you have more questions in the future.

Your temporary bridge should feel comfortable for you in all ways. Since it is plastic, issues can be worked out easily. In fact, I consider a bridge like that a "prototype" so that it can be worn and used in order to make sure the final bridge works. A copy can then be made of the "prototype" so the the final bridge is similar to what we already know works properly in the mouth.
