Summary

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. The first type of expander is made by hand in an orthodontic laboratory, and the second type of expander is designed on a computer and printed using 3D printers. 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 follow-up visits including photos, x-rays, and dental photo scans over the course of 6 months to see how the expander is working. In addition, as part of the research study, the participant will be asked to complete paper questionnaires with assistance from parents or guardians about his/her quality of life and perception of possible pain and discomfort at different time points. The potential benefits of this study include the use of 3D technology to improve the quality of the orthodontic treatment, with more comfort to the patient.

Summary

Dental caries, or the bacterial process that causes cavities, is the most common chronic disease affecting children. For many children requiring treatment of the front teeth, there is an esthetic concern affecting treatment. A common material used to treat cavities that affect the nerve of the tooth can cause tooth discoloration. This study aims to determine whether a white crown can mask that discoloration, thereby reducing the esthetic concern for the use of this material. Because this material has many great qualities and is the standard of care for these nerve treatments, this may eliminate any esthetic concern and allow dentists to provide the best care for these children.
