Otherwise, the implants will restrict further intrusion B) If there is to be no mesiodistal movement of the adjacent teeth, the insertion position is located on the central line. A) For mandibular molar distalization, an insertion position 1.5 mm distal to an imaginary central line between two teeth should be selected. C) For molar protraction, an insertion position 1.5 mmmesial to an imaginary central line should be selected.
