An orthodontic separator, said separator dimensioned such that it can be inserted between adjacent teeth, said separator being characterized in that when inserted between adjacent teeth in the oral environment, it exhibits an increase in compressive force, wherein the separator exerts sufficient force on the adjacent teeth to push the teeth apart.
A method for separating a pair of adjacent teeth in a patient's mouth comprising inserting an orthodontic separator between the adjacent teeth, wherein upon insertion said separator exhibits an increase in compressive force and expands to exert sufficient force on the adjacent teeth to push the teeth apart.
A method for separating a pair of adjacent teeth in a patient's mouth comprising inserting an orthodontic separator comprising a shape memory material between the teeth, wherein upon insertion said separator is heat activated to exert sufficient force on the adjacent teeth to push the teeth apart.
