From $780 to $1000 per veneer.Make sure your dentist is using a reputable lab.The intrinsic shade should also be given to your lab, this may affect the outcome of your veneers.
A refinement is usually included in a full case. These are cases with more than 10 trays per arch. More than one refinement is not unusual especially for more difficult cases. I see approximately 20 percent of my cases required refinements. Invisalign will charge a fee for refinements that are pass the deadline for refinements.
You can try invisalign to move the teeth out of edge to edge. There will be some maintenance with veneers when the bite is edge to edge, such as possibility of chipping. Try whitening your teeth with invisalign combination first. I believe your natural teeth is still the best. The invisalign will align the tooth to allow a more conservative prep if you decide to have veneer later. I have done full mouth crowns that you are able to adjust the occlussal clearance so the patients bite is not edge to edge. I usually do this only because the patient is very unhappy with the esthetic of all the teeth. Which is usually badly stain and with substantial amount of wear. Daniel Huang, DDS
