A Clinical Comparison of the Effectiveness of Two Types of Orthodontic Aligning Archwire Materials

Iraq31 participantsStarted 2019-01-03

Plain-language summary

The aim of this study is to compare the effectiveness of using heat-activated NiTi with superelastic NiTi archwires during the initial phase of orthodontic treatment. Primary Objective: To compare the difference in the amount of crowding in the lower incisors after 4 and 8 weeks from the start of treatment. Secondary Objectives: 1. To compare the amount of orthodontically-induced inflammatory root resorption (OIIRR) in the apical region of mandibular central incisors between the two groups of archwires 2. To compare the amount of pain perception between the two groups of archwires during the 1st week after each wire placement.

Inclusion criteria

✓. Patients indicated for fixed appliance orthodontic treatment who have a moderate crowding (3-6mm) according to the Little's irregularity index (LII).
✓. Full set of lower permanent dentition excluding the third molars.
