Abstract

The aim of this study is to evaluate the performance of a newly developed Ni-free SMA wire as an orthodontic wire by comparing with a Ni-Ti wire. A Ti-Nb-Al superelastic wire or an orthodontic superelastic wire (Ni-Ti wire) was set in the mouth of male Wistar-strain rats, and orthodontic palatal movement of maxillary first molars was performed with an initial load of 15 gf. The amount of tooth movement was measured and periodontal structures were observed using microfocus X-ray CT radiographs. There was no significant difference in the amount of movement between the Ti-Nb-Al group and the Ni-Ti group. Microfocus X-ray CT observation revealed no morphological differences between the two groups. Our results indicate that the Ti-Nb-Al wire can be a comparable orthodontic wire to the Ni-Ti wire.
