Comparative evaluation of anchorage loss and canine retraction rate using mini-implant anchorage versus conventional molar anchorage

Orthodontic anchorage control during space closure is critical to prevent unwanted tooth movement, prolong treatment and maintain facial aesthetics. This randomised controlled trial compared mini-implant versus conventional molar anchorage (transpalatal arch) in 40 premolar extraction patients for bilateral canine retraction over 3 months. Mini-implants significantly reduced anchorage loss (0.42±0.31 mm versus 2.18±0.67 mm, p<0.001) compared to conventional anchorage. Canine retraction rates were superior with mini-implants (1.24±0.28 mm/month versus 0.89±0.22 mm/month, p<0.001). Mini-implant anchorage provides superior preservation and faster canine retraction, establishing it as the preferred choice for maximum anchorage needs.
