When interproximal reduction (IPR) has been incorporated to resolve crowding or interference, the lab will return a chart with the case showing the amount of enamel reduction and target locations for each contact point and amount of IPR done in the laboratory. Please keep in mind this is our best estimated IPR based on the actual laboratory reset through the requested stages. There is always the possibility that the actual amount of IPR required clinically may vary slightly from what was done in the laboratory based on how the teeth respond to each aligner.
