How suited are the different commercially available archwires for the Egyptian dental arches?

Background: The purpose of this study was to investigate the suitability widths some commercially available preformed NiTi arch wires dental a sample Egyptian population.Methods: This cross-sectional included 420 maxillary and mandibular pairs casts for subjects with an age range 10-16 years as part project by National Research Centre. were traced using TracerNet; intercanine intermolar measured on casts. Anterior posterior lengths facilitates measurements wires. eight archwires graph paper. Results: Regression analysis performed create regression model predicted means in different groups. mean square error (MSE) calculated all relation arch. Ormco (Broad arch/small) had lowest MSE; 1.55 upper width 1.72 width. For lower its MSE 0.30 0.31 Ortho Technology, while it 0.78 Ormco. Conclusions: considerably larger than size majority population, except Ormco; thus, inviting potential relapse treatment. It is necessary produce wider customized that better suit sizes population.
