NCT06554769 | Completed

• 1 other identifier: Cairo University (CairoU)
• Study Type: interventional
• Target: 15

Brief Summary

Indirect anchorage (In-A) has been broadly used for anchorage reinforcement during anterior segment retraction. The study compared between the efficacy of rigid vs non-rigid connections of In-A i during upper canine retraction in dentoalveolar protrusion cases

Conditions

Orthodontic Appliance Complication

Outcome Measures

Primary Outcomes (1)

• anchorage loss

  amount of anchorage loss of the upper first molar during canine retraction using digital model in mm.

  4 month

Secondary Outcomes (1)

• vertical position of the upper second premolar

  4 month

Study Arms (2)

Non-Rigid connection

EXPERIMENTAL

side received a non-rigid 0.014-inch St.St ligature ligating the upper second premolar to the miniscrew.

Procedure: non rigid indirect anchorage connection

Rigid Connection

ACTIVE COMPARATOR

rigid wire 19 x 25 inch stst wire was place between upper first molar and the miniscrew placed between the first molar and second premolar

Procedure: rigid indirect anchorage connection

Interventions

non rigid indirect anchorage connection PROCEDURE

a nonrigid connection is placed between the miniscrews and the second premolar to prevent mesial tooth movement.

Non-Rigid connection

rigid indirect anchorage connection PROCEDURE

a rigid connection is placed between the miniscrews and the first molar to prevent mesial tooth movement.
