  • MINI-SCREWS - MINI IMPLANTS IN ORTHODONTICS WWW.ORTHOFREE.COM Traction force and tooth movement. ★: Center of resistance (CR) of the dental arch. Red arrow: orthodontic traction force; Black arrows: direction of tooth movement. Parallel translation in the posterior direction is seen when the force vector is directed through the CR and remains parallel to the occlusal plane. Mitsuru Motoyoshi
  • MINI-SCREWS - MINI IMPLANTS IN ORTHODONTICS WWW.ORTHOFREE.COM Parallel translation in the posterosuperior direction is seen when the force vector passes through the CR and is directed in a posterosuperior direction. Mitsuru Motoyoshi
  • MINI-SCREWS - MINI IMPLANTS IN ORTHODONTICS WWW.ORTHOFREE.COM Depression of molars and distal movement of the anterior teeth is expected when the force vector is directed inferior to the CR Mitsuru Motoyoshi
