Effect of Force Magnitude on Canine Retraction and Gingival Crevicular Fluid Proteome

NCT06668194 · Status: RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Summary

This study aims to examine the effect of force levels in orthodontic treatment during canine retraction. Force levels refer to the pressure applied by the orthodontic devices to move teeth. Data collection will include gingival fluid, dental molds from a digital scanner, and x-rays of the upper canine region on both sides of the mouth during treatment. The null hypothesis to be tested is that there is no significant difference in the rate of canine movement between the light force and the heavy force levels.

Conditions

  • Tooth Crowding

Interventions

DEVICE

Light Force (150g Niti Coil)

Patients' participation in the study (T0) will be started at the stage of canine retraction. At this appointment, 0.019 x 0.025-inch stainless steel archwire will be placed; power arms will be fabricated from 17x25-inch stainless steel on the maxillary first molars and canines. The height of the power arm will be matched with the center of resistance of both canines and molars based on the root length measured on the periapical radiographs. The archwire will be engaged in the canine bracket using stainless steel ligature wire. NiTi coil spring calibrated for force magnitude (150g) at oral temperature will be used to deliver the assigned force will be engaged from the first molars to the canine power arms

DEVICE

Heavy Force (400 g Niti coil)

Patients' participation in the study (T0) will be started at the stage of canine retraction. At this appointment, 0.019 x 0.025-inch stainless steel archwire will be placed; power arms will be fabricated from 17x25-inch stainless steel on the maxillary first molars and canines. The height of the power arm will be matched with the center of resistance of both canines and molars based on the root length measured on the periapical radiographs. The archwire will be engaged in the canine bracket using stainless steel ligature wire.
