Abstract: Background: Addressing the needs of young adults undergoing orthodontic for
faster treatment with unrealistic requirements has become challenge in modern era to
orthodontists. So, to meet the treatment needs of the patients a combined multidisciplinary
approach of orthodontists and oral surgeon is required. Various techniques are emerging in
accelerated orthodontics field. Piezosurgery being a novel minimally invasive technique has
shown to be a emerging trend with good results with the piezocision technique. Objectives: We
aim to evaluate and compare the conventional corticotomy with piezo-guided corticotomy in
accelerated osteogenic orthodontic treatment. Methods: This randomized comparative study
has sample size of 24 subjects equally divided in two groups, i.e. conventional corticotomy
group done with bur and piezo-guided corticotomy group. The time required for the surgical
procedure, rate and amount of tooth movement and total treatment time required for
completion of space closure was measured. Along with this, secondary parameters like
gingival recession, periodontal pocket formation and dehiscence/ fenestration formation were
also assessed. Results: Piezosurgery being minimally invasive requires more time for surgical
procedure, however, it more efficiently moved tooth with reduced total treatment time when
compared to conventional corticotomy. The piezosurgical group resulted in faster rate as well
as amount of tooth movement than bur group. Although there was no statistically significant
difference evident in complications associated with accelerated orthodontics tooth movement.
Conclusion: A novel, minimally invasive approach for surgical orthodontics with better
patient acceptance is equally effective in accelerating orthodontic tooth movement and
definitely widen the scope of surgically accelerated orthodontic treatment with prognostically
satisfactory clinical outcomes.

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.
