Summary

This study tests whether giving vitamin D3 locally and using a minor surgical technique called corticision can make orthodontic tooth movement faster. Sixteen patients aged 13-20 who need premolar extractions will be followed for 12 weeks. The goal is to see if these methods safely speed up canine retraction and improve bone density.
