6. Refinement Schedule

For Invisalign Full and Invisalign Anterior,

if under-achieved teeth movement remains / space between teeth persists /

sound biting between upper and lower back teeth is still to be achieved,

charge-free course of Refinement is provided at the completion of main Invisalign treatment course. ( except in the case where the Invisalign main treatment course completion gets delayed excessively for some reason, Invisalign USA will request additional fee for Refinement course)

For Refinement course, new PVS impression + Photo images will be taken again and you will need to maintain teeth alignment by wearing the appropriate aligners ( or retainers) to prevent any unwanted teeth movement before you receive Refinement aligners.
