No results posted yet for this study

Summary

Sixty patients requiring extraction-based treatment of the maxillary first premolars, followed by retraction of the maxillary canines, will be randomly assigned to three groups: piezocision, low-level laser therapy, and control. In each group, canine retraction will be initiated after completion of the leveling and alignment phase, using closed nickel-titanium coil springs that apply 150 g of force per side. For anchorage, a soldered transpalatal arch will be used.

Pre- and post-distalization dental casts will be assessed to evaluate the rate of canine retraction, canine rotation, and anchorage loss over the follow-up period until a Class I canine relationship is achieved. Periodontal health will be assessed before and after canine retraction by evaluating the following parameters: plaque index, gingival index, bleeding index, and probing depth.

Conditions

  • Class II Malocclusion

Interventions

PROCEDURE

Piezocision

After anesthesia, three vertical incisions will be made (3-mm depth and 8-10 mm length) mesial and distal the upper canine as well as at an equal distance from the upper canine and 2nd premolar. The surgical procedures will be repeated after six weeks (only the mesial and distal canine incisions will be done)

DEVICE

Low-level laser

GaALAs diode laser (wavelength: 810 nm and exposure time of 10 seconds\\point) will be applied around the upper canine in 10 sites from buccal and palatal. The middle of the extraction site will be also irradiated in 4 sites (2 buccally and 2 palatally). The LLLT will be applied 5 times in the first month of canine retraction, then every two weeks until class I canine relationship will be achieved.

DEVICE

Conventional treatment

The upper canine destalization will be done using NiTi springs. The force level will be controlled every 2 weeks. Retraction will be stopped when a class I canine relationship in both sides.
