Malocclusion Class II Clinical Trial
Official title:
Three-dimensional Judgment of Mandibular Condylar Volume and Position Subsequent to Twin-block Functional Therapy of Skeletal Class II Malocclusion Accompanied With Low-level Laser Therapy
to evaluate effect of low-level laser therapy (LLLT) on mandibular condylar volume and
position after treatment of Class II malocclusion with Twin Block (TB) functional therapy via
cone beam computed tomography (CBCT).
Materials and methods: Twenty eight growing patients, 14 boys and 14 girls ranged in age 9-12
years, were randomly divided into control group (mean initial age 10.64±1.36 years) and laser
group (mean initial age 10.55 1.45 years). All patients treated with TB appliance where
Gallium aluminum arsenide diode laser applied in one group weekly around TMJ region for 12
sessions in three months with set parameters: continuous 635 nm, 50 mW, 4.5J/cm2, 45 seconds/
point, total dose per side 11.25J. CBCT were obtained before and immediately after TB
therapy, in addition to routine orthodontic records. Changes in TMJ and skeletal variables
were analyzed and compared within and between both groups.
