Maxillary first molar is the key in normal occlusion.
Mesial drifting of maxillary first molar result from early loss of second deciduous molar. Mesial drifted maxillary first molar was treated by headgear, Hawley appliance with screw, brasswire, etc. But, these appliance should be necessary for
patients
cooperation.
recently, several appliance for molar distalizing without patients cooperation has been introduced.
We are reporting in this paper about distalizing of mesial drifted maxillary first molar because of early loss of deciduous second molar by open coil jig.
Distalization of molar by open coil jig is predictable, rapid, painless method without mecesscity of patient cooperation.
