Objectives: To Compare between two types of nickel titanium arch wires during initial orthodontic alignment as regards bone thickness change and root volume change.
Methods: This randomized clinical trial included patients aged 13 and 23 years, selected from the orthodontic outpatient clinics at Al-Azhar University, Assiut. Patients with Class I malocclusion, Little’s irregularity index 4-6 mm and non-extraction treatment of the maxillary arch were randomly assigned to receive two types of alignment arch after randomly grouping to conventional NiTi group and Cu-NiTi group. Four sizes of wire (14,16,18,16*22) were used in present study, every wire change after 28 days and place the next archwire. before initial (T0) and final (T1) archwire cone beam CT was taken to evaluate the change regarding bone thickness and root volume.
Results: Comparison between the two groups revealed no significant statistical differences in bone thickness across all root levels, nor in root volume alterations after alignment.
Conclusion: These two types of Ni Ti archwires produced comparable effects on bone thickness at various root levels as well as on root volume changes.
