The Predictability of Directly Printed Versus Thermoformed Clear Aligners
Sponsor: University of Baghdad
Summary
The study is randomized controlled trial ...The null hypothesis suggests that there is no significant difference between actual and predicted dental movement in patients treated using direct printed aligners produced with Graphy™ Tera Harz TA-28 resin as compared to those treated with thermoformed clear aligner therapy.

Interventions
Direct-printed aligner (Graphy)
intraoral scanner would be used to scan patient teeth then aligner fabrication by direct printing then the patient will be treated with direct-printed aligners(graphy) until dental levelling alignment; space closure is finished. All patients would be given the same instructions: aligners had to be worn for at least 22 hours per day, except during meals and oral hygiene activities, and should be changed every 10 days.
Thermoformed aligner
intraoral scanner would be used to scan patient teeth then aligner fabrication by thermoforming then the Patients will be treated with thermoformed aligners (secret aligners) until dental alignment, levelling, space closure is finished. All patients would be given the same instructions: aligners had to be worn for at least 22 hours per day, except during meals and oral hygiene activities, and should be changed every 10 days.
