Comparison of Jones jig molar distalization appliance with extraoral traction.
In this study, 20 patients were evaluated. Ten were treated with intraoral distalization followed by fixed appliance therapy, and 10 were treated with extra oral traction followed by fixed appliance therapy. Molar relationship correction was achieved in 2.5 months with intraoral distalization and in 10.7 months with extraoral distalization. A significant anterior movement of the anchorage unit (P <.001) was observed with the intraoral distalization and a significant distal drift of premolars was observed in the headgear group (P <.05). Palatal plane was found to tip downward significantly in the headgear group (P <.05). Total outcome of the 2 methods were discussed evaluating the advantages and disadvantages of the 2 distalization methods.
