LLLLT vs Piezocision in Accelerating Orthodontic Canine Retraction

Effectiveness of Piezocision Versus Low-level Laser Therapy During Orthodontic Canine Retraction: A Comparative Controlled Clinical Study

This comparative controlled clinical study aims to evaluate and compare the effectiveness of piezocision and low-level laser therapy (LLLT) as adjunctive interventions to accelerate orthodontic canine retraction. Participants will be randomly assigned to one of three groups: piezocision, LLLT, or a control group (no adjunctive procedure). The study will assess the impact of these interventions on the rate of tooth movement, the type of tooth movement, and patient experience.

Inclusion Criteria:

• Age range 18-25 years.
• Patients with crowding or protrusion requiring at least bilateral maxillary first premolar extraction followed by symmetrical canine retraction.
• Full set of permanent dentition (third molar not considered).
• Patients with good oral hygiene.

Exclusion Criteria:

• Previous orthodontic treatment.
• Patients taking medications or suffering from systemic conditions that can affect orthodontic tooth movement.
• Active periodontal diseases and/or untreated carious lesions.
• Congenital orofacial deformities.

Discontinuation criteria:

• Multiple missing appointments.
• Poor oral hygiene.
• Multiple broken appliances to the extent that interferes with obtaining the treatment objectives.
