| description | AIMS: To evaluate the alignment efficiency and colour performance of four coated nickel-titanium
aligning archwires over an eight-week period. The aim was to establish whether the latest aesthetic
archwires have dispelled their reputation.
SUBJECTS AND METHOD: One hundred and twenty participants requiring fixed appliance orthodontic
treatment had each dental arch randomly allocated to one of four interventions: (1) Forestadent®
BioCosmetic® 0.017 inch (2) Forestadent® Titanol® Cosmetic 0.016 inch (3) TP Orthodontics
Aesthetic 0.014 inch (4) Ortho Organizers® Tooth Tone® 0.016 inch. The archwires were ligated and
remained in situ for an eight week period. Changes in Little's Irregularity Index were measured on
dental casts using digital callipers and retrieved archwires were measured for colour change (ΔE) and
coating loss. Colour assessments were made using digital photography and Adobe® Photoshop®, with
ΔE values computed using the CIE L*a*b* system. Coating loss was measured by analysing digitally
scanned images and using Autodesk® AutoCAD®.
RESULTS: One hundred and nineteen patients (74 females, 45 males) completed the trial. Significant
alignment was achieved in all groups, however, one-way ANOVA showed no difference in alignment
efficiency among the four groups. All four archwires showed significant mean colour change and
coating loss after clinical use. One-way ANOVA showed a statistically significant difference between
the archwires for ΔE (P = 0.001), with Titanol Cosmetic showing the greatest statistically significant
colour change. There was no statistically significant difference between the archwires for coating loss.
CONCLUSION: There was no difference in alignment efficiency amongst the coated archwires used,
however there was appreciable colour change and coating loss after clinical use of coated aligning
archwires. The aesthetic properties of these coated archwires are not ideal. |
