Ghost IPR 2.0

I. Introduction

Dr. Amanda clarifies the concept of “ghost interproximal reduction” (IPR) in Invisalign treatment planning. She explains that ghost IPR refers to virtual IPR added to refine slight open contacts at the end of treatment when everything else in the case is perfectly aligned. Dr. Amanda emphasizes that ghost IPR should only be used as a “quick fix” for minor issues, not to address major tooth size discrepancies, crowding, or anterior contacts. She outlines the exact workflow for when ghost IPR is indicated, stressing the importance of addressing all other alignment and occlusal issues before considering this final detail refinement of light contacts with a few final aligners.
