a Images of MSB-based orthodontic treatment of rabbit incisors in vivo. b Timetables of three stages of MSB-based orthodontics associated with a total incisor movement of 2.5 mm. PT refers to the post-treatment status. c The control group without the MSB aligner resulted in undesirable tooth movements and malocclusion. d Front view of three-dimensional scanned tooth movement profiles when the MSB aligner was applied. e Top view images of the tooth with progressing malocclusion without the MSB aligner. θday indicates the incisal edge angulation on the specific day after interproximal reduction surgery. Δθ denotes the undesirable inward rotation determined as θ0 - θday.
