NCT04229797

Brief Summary

A clinical study to test the capability of the mini-screws inserted in the Mandibular buccal shelf area as an anchorage unit to distalize mandibular first molar for correction of mild to moderate Class III cases. The second aim was to detect if there is a difference in the amount of distalization in the presence of unerupted mandibular third molars, using the same technique.

Outcome Measures

Primary Outcomes (1)

  • Dental effect

    Amount of first mandibular molar distalization (mm) in the two groups, A cephalometric of pre and post distalization digital cephalograms will be traced, landmarks and reference lines will be determined; skeleto-dental and soft tissue measurements will be performed using Quick-Ceph program . Digital models of pre and post distalization will be superimposed and measured for dental changes using Anatomage program.

    6 months

Secondary Outcomes (1)

  • Skeletal and soft tissue effect

    6 months
