Sutural loading in bone‐ versus dental‐borne rapid palatal expansion: An ex vivo study

Abstract: Transverse maxillary deficiency is a prevalent skeletal problem and has been associated with impairments in oral function and breathing. 1 As first described by Emerson Angell in 1860, 2 rapid palatal expansion has been the treatment of choice for transverse maxillary deficiency. Typically, it is accomplished using dental-borne rapid palatal expansion (DRPE), using maxillary teeth as a point of force application. This separates the midpalatal suture (MPS) resulting in bone formation along the sutural edges. 3,… Show more

“…This is advantageous because it has few adverse effects on the anchor teeth; however, the amount of maxillary intermolar width expansion might be small and clinically ineffective in improving posterior crossbite. 20 In contrast, MARPE, a tooth and bone-borne RPE in which four teeth and four miniscrews play the role of anchors, evenly distributes stress on the anchor teeth and miniscrews. As a result, buccal crown tipping of the anchor tooth and the stress on the buccal plate can be reduced, and a clinically usable amount of the maxillary intermolar width can be obtained.…”

“…The bone‐borne expander can effectively focus on the split of the midpalatal suture, by applying all distraction forces to the miniscrews placed near the midpalatal suture. This is advantageous because it has few adverse effects on the anchor teeth; however, the amount of maxillary intermolar width expansion might be small and clinically ineffective in improving posterior crossbite 20 . In contrast, MARPE, a tooth and bone‐borne RPE in which four teeth and four miniscrews play the role of anchors, evenly distributes stress on the anchor teeth and miniscrews.…”

“…Several studies investigated the biomechanical behavior of jackscrew appliances through finite elements analysis [39][40][41][42] or in both in vitro [39,[43][44][45] and in vivo settings [46][47][48][49][50]. However, the underlying biological processes behind maxillary skeletal expansion remain inadequately understood, and the clinical parameters for predicting expansion success are still lacking.…”
