No results posted yet for this study

Summary

Patients with severe crowding requiring the extraction of four premolars will be enrolled in this study. The degree of apical root resorption associated with using the clear aligner technique compared with vestibular fixed appliances in the treatment of severe crowding malocclusion cases requiring the extraction of first premolars will be evaluated using cone beam computed tomography (CBCT) volumes.

There are two groups:

First group (Experimental): the patients in this group will be treated using clear aligners.

Second group (Control): the patients in this group will be treated using fixed appliances.

Conditions

  • Malocclusion, Class I/II
  • Crowding, Tooth

Interventions

DEVICE

Clear Aligners

In-house 3D-fabricated clear aligners will be used.

DEVICE
