Accelerated Canine Retraction by Using Mini Implant With Low-Intensity Laser Therapy

Area of Science:

• Orthodontics
• Biotechnology

Background:

• Accelerated orthodontics aims to reduce treatment duration.
• Conventional orthodontic treatment typically lasts 2-3 years.
• Prolonged treatment increases risks like root resorption and caries.

Purpose of the Study:

• To evaluate the efficacy of low-level laser therapy (LLLT) for accelerated canine retraction.
• To compare LLLT-assisted orthodontics with conventional canine retraction.

Main Methods:

• Split-mouth study design with 20 patients requiring premolar extraction.
• Miniscrew implants used for anchorage.
• 940 nm aluminum gallium arsenide diode laser applied at specific intervals.

Main Results:

• LLLT group showed a significantly higher canine retraction rate (0.81 mm/month) vs. control (0.74 mm/month).
• Average increase in tooth movement was 40.1% in the LLLT group vs. 36.3% in the control group.
• Pain scores decreased significantly between Day 3 and Day 30 in the LLLT group.

Conclusions:

• LLLT combined with accelerated orthodontics increases canine retraction rate.
• LLLT is a safe, minimally invasive technique for faster orthodontic tooth movement.
• LLLT offers pain relief after 24-72 hours, not immediately.
