Invisalign IPR is a Important Part of Many Orthodontic Treatments

Your Toronto Invisalign specialist is the one who plans how your teeth will move using the ClinCheck program provided by Align Technology.  Often times, space is required to move the teeth, but the crowding is not severe enough to warrant extraction, but cannot be achieved by dental expansion.  This is not unique to Invisalign but is used with traditional braces as well.  In these cases, Interproximal Reduction (aka IPR, slenderizing, discing, shaving, polishing) may be employed.
