Abstract

Abstract: Background: Accelerated orthodontics aimed at reducing orthodontic treatment
duration. The main setback that occurs in the treatment of patients who require first premolar
extraction is the distalization of the canines, which requires longer treatment duration. There
are many surgical techniques evolved to accelerate tooth movement. So this study will help us
to evaluate and compare canine retraction rate between two surgical techniques i.e
corticotomy facilitated orthodontics and piezocision technique. Objective: The main objective
of this study is to compare rate of canine retraction in corticotomy facilitated orthodontics and
piezocision technique. Methods: The sample consisted of 22 patients (15-25 years old) with
Class II Division 1 malocclusions. The suggested treatment plan for the given sample was
extraction of the maxillary first premolars with subsequent canine retraction. Split mouth
study design was selected for study. After initial leveling and alignment, first premolar will be
extracted then one side was assigned for corticotomy and contralateral side for piezocision in
the area of first premolar and canine retraction was initiated bilaterally with 0.019×0.025 SS
wire in slot. Study models will be obtained presurgery T0 and postsurgery at T1, T2 and T3
time interval. The following variables were examined over a 3-month follow-up period: rate of
canine retraction, molar anchorage loss, canine rotation with the help of study model. Results:
This study will found that rate of canine retraction will be more in corticotomy facilitated
orthodontics when compared with piezocision. Conclusion: This study will conclude that
corticotomy will be more efficient technique for canine retraction when compared to
piezocision.
