Removable Devices in Palatal Expansion

May 11, 2023 updated by: Eleonora Ortu, University of L'Aquila

Comparison Between Removable Devices in Palatal Expansion: a Randomized Open Label Clinical Trial

The goal of this clinical trial si to compare two removable devices used to treat the transversal discrepancies in growing patients.

The main questions it aims to answer are:

  • the efficacy of the two devices in the palatal expansion
  • the neuromuscolar effects developed on the stomatognatic system Participants will be instructed in the use and maintenance of the devices and will be checked every 15-30 days for one year.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Elastodontic removable device
Patients in this group will be treat with an elastodontic device adapted to the patient according to the shape of the dental arches. This device is similar to a mouthguard and embraces both dental arches. This appliance is worn overnight and the patient will be checked every month. The distance between the palatal cusps of the first upper premolars will be taken at T0( before the start of the therapy), at T1 (after six months)and at T2 (after one month). All the dental recors will be taken by the same operator with an intraoral scanner 3D.
Device: Elastodontic Device
Removable device that embraces two dental archs
Experimental: Schwarz removable device
Patients in this group will be treat with a Schwarz removable device constructed individually by the dental technician.This device has a resin baseplate with an activation screw in the center and Adams hooks on the upper first molars and it works by turning the expansion screw in the center of the palate one-quarter turn, once or twice a month by the ortodontist. This appliance is worn overnight and some hours during the day (totally 16 hours).The distance between the palatal cusps of the first upper premolars will be taken at T0( before the start of the therapy), at T1 (after six months)and at T2 (after one month). All the dental recors will be taken by the same operator with an intraoral scanner 3D.
