"Sliding Jigs vs Retraction Hooks for Maxillary Dentition Distalization Using IZC Miniscrews"
A Comparative Evaluation of Whole Maxillary Dentition Distalization Using Sliding Jig vs. Retraction Hooks Anchored by IZC Miniscrews: A Randomized Clinical Trial
Sana'a University
40 participants
Feb 1, 2026
INTERVENTIONAL
Conditions
Summary
This randomized controlled clinical trial aims to compare the clinical efficacy, efficiency, and biomechanical differences between two methods for total maxillary dentition distalization: (1) the use of a Sliding Jig and (2) the use of Retraction Hooks, both anchored by Infrazygomatic Crest (IZC) miniscrews. The study will assess rates of distalization, anchorage loss, dentoalveolar tipping, patient comfort, and treatment-associated side effects.
Eligibility
Exclusion Criteria1
- The subjects having the following conditions will be excluded from the study (1) Patients with transverse dental or skeletal discrepancies. (2) Patients indicated for extraction treatment (except for third molars) or unilateral distalisation treatment (3) Patients with Vertical growth pattern, (4) Patients having periodontal disease, (5) Patients with previous orthodontic treatment.
