Root Resorption
Conditions
Keywords
Two step retraction, En masse retraction, Cone Beam Computed Tomography
Brief summary
The goal of this study is to compare the three dimensional root resorption after extraction space closure in two groups: two step retraction and en masse retraction. Th main aim of this study is to conclude which method is less damaging to the roots. Participants will be divided into two groups: 1. En masse retraction (experimental) 2. Two step retraction (control) Pre retraction and post retraction CBCT scans will be compared for both groups.
