Brief 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.

Interventions

PROCEDURELow Level Laser Therapy

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.

PROCEDUREPiezocision

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.

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.

Design outcomes

Primary

MeasureTime frameDescription
Rate of canine retractionFour months from the beginning of maxillary canine retraction.The rate of distal movement of the maxillary canine measured in millimeters per month (mm/month).

Secondary

MeasureTime frameDescription
Maxillary canine rotation and tipping.Four months from the beginning of maxillary canine retraction.Measured in degrees
Maxillary first molar mesial movementFour months from the beginning of maxillary canine retraction.Maxillary first molar mesial movement (measured in mm)
Maxillary first molar rotatiobFour months from the beginning of maxillary canine retraction.(measured in degrees).
Patient-Reported Pain IntensityFour months from the beginning of maxillary canine retraction.Pain intensity will be measured using a 10-centimeter Visual Analogue Scale (VAS). The scale ranges from 0 to 10, where 0 represents "no pain" and 10 represents "the worst possible pain" . Therefore, higher scores indicate a worse outcome (greater pain intensity).
