Precision Orthodontics: Virtual Treatment Planning for Orthodontic Braces
Status unconfirmed · Not applicable
Conditions studied: Malocclusion, Malocclusion, Angle's Class
In brief
The investigators are evaluating the effectiveness of custom-made 3D-printed ceramic (tooth-colored) brackets (braces) compared to conventional tooth-colored brackets (braces). Participants will be expected to come in for regularly scheduled appointments. They will be treated with tooth-colored braces and will need to come in every 4-6 weeks and will be randomly assigned to one of three groups. "Randomly" means by chance, like a coin toss. Neither participants nor the researchers may choose group assignments. Group 1 patients will have tooth-colored braces placed directly on each tooth by the clinician. Group 2 patients will have the braces placed on the teeth by using trays to fit them on. Group 3 patients will have customized 3D printed tooth-colored braces placed on their teeth, using trays to fit them on. If a participant is selected to be part of group 3, it may take up to two additional weeks for these 3D brackets to be printed and shipped and so this might delay treatment onset. Information on gender, age, and medical history of participants will also be obtained from the electronic health record.
