Efficacy of Minimally Invasive Surgical Technique in Accelerating Orthodontic Treatment
Evaluation the Efficacy of Flapless Corticotomy Accomplished by Either Hard-laser or Piezosurgey in Accelerating Upper Canine Retraction and Evaluation of the Dento-alveolar Changes and the Levels of Acceptance and Discomfort.
Thirty six patients needs therapeutic extraction of the maxillary first premolars with subsequent retraction of the maxillary canines will be divided randomly into two groups : piezocision group and the ER:yttrium aluminum garnet (YAG) laser group. In each group, piezocision or hard laser-assisted flapless corticotomy will randomly assigned to one side of the maxillary arch at the first premolar region, and the other side served as the control. Canine retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side, soldered trans-palatal arch will be used as an anchor unit.
Pre- and post distalization dental casts will be evaluated to study rate of canine distalization, canine rotation and anchorage loss over a follow-up period until a Class I canine relationship is achieved. The levels of pain and discomfort will be self-reported using a questionnaire with visual analog scales administered at four assessment times during the first month after the minimally invasive procedure.

Detailed Description
One main issue in orthodontics is the prolonged treatment time, leading patients, especially adults, to avoid treatment or seek alternative options such as implants or veneers with less than optimal results.
Therefore, the search for methods that decrease the treatment duration is a main challenge in orthodontic research. Decreased duration of therapy seems to be related not only to better patient compliance, but also to reduced treatment -related root resorption , better periodontal health and lower risk of caries and white spots. Adjunct to the proper selection of brackets, wires, biomechanic systems, force levels, and anchorage systems, an array of novel techniques has been introduced to accelerate orthodontic tooth movement. These techniques can be briefly categorized as surgical and non-surgical. However The surgical approach is the most clinically used and most tested with known predictions and stable results. The invasiveness of surgical procedures, requiring full mucoperiosteal flaps, might have been a drawback for their widespread acceptance among orthodontists and patients. Therefore, more conservative flapless corticotomy techniques have recently been proposed. Although various techniques of flapless corticotomy have been reported to be successful in practice, scientific evidence for their effectiveness so far has been limited to case series and a handful of clinical trials, generally with small groups. Therefore further controlled prospective studies are needed to study the effectiveness of flapless corticotomy in accelerating orthodontic tooth movement .

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of canine retraction
Time Frame: This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which takes up to 12 weeks
|
The distance traveled by mm is divided by the time required in weeks.
|
This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which takes up to 12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of molar anchorage loss
Time Frame: This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which may take up to 12 weeks
|
The amount of mesial movement of the first molar in millimeters (mm) is divided by the time required to retract the upper canines (in weeks).
|
This will be measured immediately at the end of the tooth movement, i.e. when the retracted canine reaches its final position which may take up to 12 weeks
|
Change in canine rotation
Time Frame: This will be measured at the following assessment times: T1: baseline, T2: after 4 weeks of canine retraction, T3: after 8 weeks of canine retraction, T4: when the canine reaches its final position up to 12 weeks
|
This measurement will be performed on plaster models taken at the aforementioned assessment times.
|
This will be measured at the following assessment times: T1: baseline, T2: after 4 weeks of canine retraction, T3: after 8 weeks of canine retraction, T4: when the canine reaches its final position up to 12 weeks
|
Change in the levels of pain and discomfort
Time Frame: These levels will be assessed at: one day following the intervention, one week, two weeks, and four weeks following the intervention.
|
Assessment will be performed using questionnaires via visual analog scales.
|
These levels will be assessed at: one day following the intervention, one week, two weeks, and four weeks following the intervention.
