Effectiveness of Piezocision or the Combination of Piezocision and Low-level Laser Therapy on Orthodontic Tooth Movement During En-masse Retraction and the Associated Dentoalveolar Changes: A Three-arm Randomized Controlled Trial
In Brief
A clinical study evaluating Piezosurgery and GaALAs diode laser, Piezosurgery, and 1 other intervention for Angle Class II. Completed, enrolled 63 participants across 1 site.
Detailed Summary
Sixty patients who need extraction-based treatment of the maxillary first premolars with subsequent retraction of the maxillary anterior teeth will be divided randomly into three groups: piezocision group, piezocision with low-level laser therapy group, and control group. In each group, after the levelling and alignment phase is completed, the rectangular stainless steel archwires (0.019" × 0.025") will be inserted, then after two weeks, the en masse retraction will be started via closed nickel-titanium coil springs applying 250 g of force per side. For anchorage, mini implants will be inserted between the second premolars and the first molar on each side.
Study Details
Timeline
Interventions
One incision will be made between the roots of the six upper anterior teeth, and two incisions will be made between the upper canines and the second premolars. The incisions will be 5 mm long and start 4 mm apical to the interdental papilla. After six weeks of piezosurgery, GaALAs diode laser (wavelength: 810 nm and exposure time of 10 seconds\\point) 10 seconds per point will be applied.
