Participant Flow

This is a split-mouth pilot study. A total of 12 participants were enrolled. 24 adult canine teeth were randomized 1:1 to the control and intervention conditions (sides Rt vs Lt) resulting in 12 canines receiving the control treatment and 12 canines receiving the intervention. A total of 6 participants completed the study.6 canines receiving the control treatment and 6 canines receiving the intervention.

Unit of analysis: Right vs left canine

Participant milestones

Measure
Control
Control: Stainless steel (18% Chromium and 8% Nickel) used as the control, and linked anteriorly to the GUMMETAL counterpart. Size of archwire is 0.016 x 0.022". Stainless Steel (CrNi): Stainless steel (18% Chromium and 8% Nickel) used as the control, and linked anteriorly to the GUMMETAL counterpart. Size of archwire is 0.016 x 0.022"
Intervention
This is a split-mouth study. Each subject was allocated to both the control and intervention groups. The unit of assessment is the right and left maxillary canine teeth. Intervention: TiNbTaZr (Beta-Titanium) Alloy used to manufacture orthodontic archwires. We will be using an archwire with the size of 0.016 x 0.022". GUMMETAL Orthodontic Wire: Orthodontic archwire made of TiNbTaZr alloy.
