• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Measuring the volume of root resorption by VR Mesh and 3 Matic softwares after segmentation of single anterior tooth from patient's CBCT that taken by the same device which will be used later in research with the same criteria so we compare pre and post orthodontic CBCT.[All patients have 2 sets of CBCT pre and post orthodontic treatments which mean after complete active treatment procedure for about one year.]

Secondary Outcome Measures

Name	Time	Method
Root resorption at the end of treatment compared with amount of tooth movement through VR Mesh softwares by comparing the distance that tooth moves during retraction with the volume of root resorption between the patient to see if there any relation between how long the tooth move to the amount of the root resorption.[There are two measurements in two different intervals before and after orthodontic treatment in two different lingual orthodontic techniques (which mean after complete active treatment procedure for about one year).];The amount of tooth movement in two different lingual bracket systems by super-positioning the two arches (pre and post treatment) from CBCT by VR Mesh softwares.[Measured through the pre and post orthodontic treatment CBCT by VR Mesh software (which mean after complete active treatment procedure for about one year).]
