hi
i have done some ortho cases, i dont know much about theories,in molar distalization,there is tipping and then uprighting of that molar,as just tipping does not bodily move the tooth
except in severe cases of low gonial angle,where intrusion is not possible and difficult as well
in molar distalization,first step is tipping ,which also slightly supraerupts the tooth and then uprighting.the other way of distalizing is making mesial teeth as anchorage and the spring pushes the molar distally,even that is not v easy,so not routinely carried out
i have seen intrusions being done routinely , but not molar distalizations
another difficulty, is the eruption time and position of molar distal to the molar 2 b distalized
intrusion can almost b done at any age,but, comparatively ,not molar distalization............eruption times hav 2 b seen or 8 has 2 b extracted 2 make the space available
these are the clinical probs faced regarding distalization,do tell me if there is smthing else in theory
