About this document
Space Closure in Preadjusted Appliances by sonal agarwal is a document available to read on EtoBox.
Once space closure is needed after alignment, the remaining extraction space can be closed through anterior retraction, posterior protraction, or a combination. There are two approaches for space closure - using a continuous archwire where friction predicts tooth movement, or bending loops into the archwire which provides more precise anchorage but requires reactivation. Retraction mechanics can be divided into friction mechanics using sliding brackets or frictionless mechanics using loops or springs to mov
