What the trial is, and whether it could suit you

Maxillary expanders are orthodontic appliances that are commonly used to expand the upper jaw. The purpose of this study will be to compare the effects produced by two different maxillary expanders in children 8-13 years old.

Both expanders are already used in the MUSC Orthodontics Clinic. The purpose of this study is to see if the 3D printed expander is as effective as the traditional expander made by hand in the laboratory, with more comfort to the patient. Patients participating in the study will be randomly assigned to one of two groups: group A will be treated with a laboratory-made maxillary expander, and group B with a 3D-Printed maxillary expander. Information will be collected on the participants' standard clinical foll
