Orthodontic force causes an injury to and subsequent degradation of the attachment apparatus, thus leading to the transposition of the tooth. The gingiva, however, is compressed and sometimes becomes hypertrophic with tooth movement and often shrinks after treatment. To study the effect of force on the gingiva, we applied orthodontic force in dogs and(More)
This study evaluated the static friction force created between archwires and "reduced-friction" brackets during sliding mechanics. Five different brands of "reduced-friction" brackets were used: group A: NuEdge (TP Orthodontics, LaPorte, Ind); group B: Discovery (Dentaurum, Ispringen, Germany); group C: Synergy (Rocky Mountain Orthodontics, Denver, Colo);(More)
Objectives. The aim of this study was to assess the influence of resistance to sliding on expression of superelastic properties of NiTi wires. Methods and Materials. A three-point bending test was performed for 0.014 NiTi wire engaged in self-ligating (Damon, SmartClip, In-Ovation) and conventional brackets (Victory) ligated with regular and reduced(More)
