The Nitanium Palatal Expander 2 Appliance’s action is the result of transition temperature and shape memory. Warmth within the patient’s mouth activates movement in the thermal nickel titanium energy wire toward the appliance’s pre-programmed shape. This produces the desired expansion in unison with tooth movement. Once the exact correction is achieved, the appliance stops expanding and lies passive. A light, slow, continuous force system has been shown to be associated with a more physiological adjustment, neuromuscular stability, and less relapse potential. In addition, repair keeps up with expansion. Expansion is usually completed in 2 to 4 months and retention is usually 2 to 3 months. The Nitanium Molar Rotator’s exclusive design fits an .036 x .072 lingual sheath to provide maximum control of maxillary first molars. Both molar rotation and torque control can be improved with this heat-activated nickel titanium appliance. The heat-activated nickel titanium palatal wire provides light continuous force. After the desired movement is completed, the rotator may be left in the mouth to act as a retainer or transpalatal bar. The Nitanium Palatal Expander is available in 10 individual sizes, in 2mm increments: 26mm, 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm and 42mm Indication : Molar, premolar, and cuspid expander Molar rotator Molar distalization Constrictor Anti-thumb Molar intruder Retainer Anchorage Control the vertical growth of the molars Control the vertical dimension Molar constriction Bite-opening
