Laser-assisted Flapless Corticotomy in Accelerating Canine Retraction

NCT04316403 | Completed DMC

• 1 other identifier: UDDS-Ortho-01-2020

Brief Summary

Erbium lasers have been suggested to accomplish corticotomy without flap reflection due to their attractive advantages. The current trial aimed to evaluate the efficacy of laser-assisted flapless corticotomy in accelerating orthodontic tooth movement. The secondary aim was to evaluate the patients' responses to laser application. It was postulated that canine retraction after laser-assisted flapless corticotomy would be accomplished within a shorter period compared with the conventional canine retraction method, with no significant degree of pain and discomfort.

Conditions

Class II Division 1 Malocclusion; Maxillary Prognathism; Protrusion, Incisor

Keywords

Tooth movement; Acceleration of tooth movement; Er:YAG laser-assisted corticotomy

Outcome Measures

Primary Outcomes (1)

• Change in the canine retraction rate

  The distance between the first molar labial hook and the canine bracket hook was recorded using Digital Boely gauge and then this distance was divided by the time that passed between two assessment points.

  10 minutes after laser application, one, two, four, 8 and 12 weeks after laser application

Secondary Outcomes (1)

• Change in the levels of pain and discomfort

  at the 1st day following laser application (10 minutes) and at the 3rd, 5th and 7th days following laser application

Study Arms (2)

Laser-assisted corticotomy

EXPERIMENTAL

Er:YAG laser beam was used to perform several perforations to the alveolar bone around the canine in one side of the mouth hoping that would accelerate canine retraction

Procedure: Er:YAG laser

Traditional treatment

NO INTERVENTION

Canines in this group were retracted by the conventional manner.

Interventions

Er:YAG laser PROCEDURE

This application was made before the onset of canine retraction in one side of the mouth

Laser-assisted corticotomy
