Summary

This trial aims to determine whether using a special laser (low-level laser therapy, or LLLT) in combination with a minor surgical procedure (piezocision) can safely accelerate orthodontic treatment. We are looking at its effect on two main safety issues: root shortening (root resorption) and gum health. We will compare three groups of patients who have their front teeth pulled back: one group receives the surgery and the laser, one receives the surgery alone, and one receives standard braces. We will measure root length on X-rays and check gums at the start, before the retraction phase, and after all the space is closed.

Conditions

  • Malocclusion, Angle Class II, Division 1

Interventions

PROCEDURE

Level Laser Therapy (LLLT)

Ga-Al-As diode laser (808 nm, 1.1 W, 4 J/point, 15 sec/point) applied to 32 points per session. Administered on days 0, 3, 7, 14, and then bi-weekly for a total of four sessions post-initiation, starting six weeks post-corticotomy.

PROCEDURE

Traditional treatment

Patients in this group will be traditionally treated without being subjected to corticotomy or LLLT.

PROCEDURE

Flapless Corticotomy (Piezocision)

Performed 4 days before retraction. Eighteen minimal intrasulcular incisions and cortical bone perforations (3mm depth) using a piezosurgery microsaw tip.
