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 aligners.

Conditions

  • Crowded Teeth
  • Spacing of Anterior Teeth
  • Rotation
  • Class I Malocclusion

Interventions

DEVICE

Thermoformed aligner

An intraoral scanner would be used to scan patient teeth then aligner fabrication by thermoforming then the Patients will be treated with thermoformed 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.

DEVICE

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.
