Evaluation of Treatment Outcome of Lower Incisors Crowding Using Clear Aligners With Laser Acceleration .

Evaluation of Treatment Outcome of Lower Incisors Crowding Using Clear Aligners With Laser Acceleration (Randomized Control Study) .

The present study will be performed to evaluate the effect of low-level laser therapy (LLLT) on the rate of orthodontic tooth movement through the correction of lower incisors crowding using clear aligners

This study will employ a two-arm parallel randomized clinical trial design with an allocation ratio of 1:1. The study will include participants aged 16 to 23 years with mild to moderate anterior lower crowding and Class I Angle malocclusion, presenting with a full set of teeth excluding wisdom teeth. Eligible participants will be randomly assigned to either the intervention group, receiving LLLT in addition to clear aligner therapy, or the control group, receiving clear aligner therapy alone.

Intervention:

The intervention group will undergo LLLT using the Biolase Epic X device, calibrated to 0.2 W power, 0.16 J energy, and 0.8 seconds pulse duration per point. The laser will be applied to five points on the buccal surface (cervical mesial, distal, middle root, apical mesial, and distal) and four points on the lingual surface (cervical mesial, distal, middle root, and middle apical) of the target tooth. LLLT sessions will be conducted weekly over seven sessions.

Inclusion Criteria:

1. A well-behaved, compliant, and motivated patient.
2. Patients from 16 to 23 years old .
3. Patients with mild to moderate anterior lower crowding.
4. Full complement of teeth (except for wisdom teeth).
5. Class I Angle malocclusion .

Exclusion Criteria:

1. Patients with missed anterior teeth .
2. Class II or III Malocclusion (dental or skeletal ) .
3. Any systemic diseases that may interfere with assigned treatment plan .
4. Periodontal affection especially at lower anterior teeth .
