title: A practical and effective method to increase the capacity of screws used for palatal disjunction.
abstract: In clinical situations involving accentuated atresia in the maxillary arch, palatal disjunction is called for. This treatment often requires an appliance change to achieve the desired movement. The aim of this article was to demonstrate a simple and effective method to increase the capacity of the expander screw and thus avoid the need to remove and replace it.
