Comparison of Alignment Efficiency, Arch Dimensional Changes, and Passive Extraction Space Closure Between Self-Ligating and Conventional Brackets

Brief Summary

Purpose: This study aims to compare two types of orthodontic braces - self-ligating brackets (SLBs) and conventional brackets (CBs) - to see which one aligns teeth faster, affects the width of the dental arch, and closes spaces after premolar extractions more efficiently. Who Can Join: Ages 13-30 years Moderate to severe dental crowding Skeletal Class I or mild to moderate Class II malocclusions Good oral hygiene Requiring extraction of premolars What Participants Will Do: Participants are randomly assigned to either the SLB group or the CB group. Braces are bonded to the teeth following standard orthodontic procedures. Dental impressions and measurements will be taken at baseline, 3, 6, and 9 months. No extra devices (like power chains) will be used for space closure during the study. What is Being Measured: Alignment of teeth using Little's Irregularity Index Intercanine and intermolar widths (arch dimensions) Passive closure of extraction spaces Why This Study is Being Done: The study investigates whether SLBs provide any clinical advantage over conventional braces in terms of faster alignment, arch width changes, and efficient space closure in extraction cases. This could help orthodontists make evidence-based decisions when choosing braces. Study Duration: Total observation period: 9 months Monthly follow-ups for adjustments and measurements
