Conditions
Summary
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.
Eligibility
Inclusion Criteria4
- 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 Criteria8
- 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.

Interventions
On both right and left sides, LLLT will be performed at the beginning of canine retraction, after 3, 7, 14 days, and then every 14 days for a total four-month period.
On both right and left sides, a minimally invasive flapless piezocision procedure will be performed each month from the beginning of the canine retraction for a total four-month period.
