"After completing invisalign braces, is there a need for a refinement process?"

Dr. Pang: A refinement process may be needed for some cases.   Even with conventional fixed-wire appliances some minor adjustments may be indicated. Your dentist/orthodontist may want your occlusion or bite to be refined further.   However, the amount of refinement should be minor and in the neighborhood of microns ( about a hair's width or less). Thanks for your question.
