Comparison of Maxillary Dental Expansion Using Smartee Clear Aligner With and Without S11 Expander: A Randomized Clinical Trial
ClinicalTrials.gov Studies
Summary
The NIH's ClinicalTrials.gov has registered a randomized clinical trial (NCT07533682) comparing maxillary dental expansion using Smartee Clear Aligners with and without the S11 expander. The trial will use cone beam computed tomography (CBCT) to evaluate orthodontic expansion and tooth movement in patients with posterior crossbite requiring maxillary arch expansion.
What changed
NIH's ClinicalTrials.gov has added registration NCT07533682 for a randomized clinical trial evaluating Smartee S11 expander combined with clear aligners versus conventional clear aligner expansion for maxillary arch treatment.
For compliance purposes, this study registration indicates an active clinical investigation of a dental/oral health device. Clinical investigators and healthcare providers involved in orthodontic research should note this trial for awareness, though it does not create immediate compliance obligations for non-participating entities.

Comparison of Maxillary Dental Expansion Using Smartee Clear Aligner With and Without S11 Expander: A Randomized Clinical Trial
N/A NCT07533682 Kind: NA Apr 16, 2026
Abstract
To compare the effects of Smartee S11 expander with conventional clear aligner expansion using cone beam computed tomography (CBCT).
The secondary objective is to evaluate the degree of orthodontic expansion and the type of tooth movement achieved with Smartee aligners on the maxillary arch.
Conditions: Crossbite (Posterior), Expansion of Maxillary Arch, Clear Aligner Appliance
Interventions: maxillary expander with transpalatal strap S11, conventional expantion
