text: technical question about invisalign ( professionals only please!)? i am a dental tech, and i want to do invisalign, i only have 4 teeth that need to be straightened, cuspid and lateral on upper, and cuspid and 1st bi on the lower. i need to shift the teeth posterior to this point back a little to give me a little room as these teeth are crowded, my question is should i place the pressure point on the mesio-buccal and mesio-lingual areas of each tooth that needs to be moved? invisalign requires submission of impressions and photographs for computer analysis prior to diagnosis for a case, so we can't advise you about your own treatment with virtually zero information.  it sounds like you are planning on trying to make the modifications to your own models and doing a series of appliances.  if so, good luck.  you are correct in theory, though.  the movement would start at the most posterior tooth and proceed tooth-by-tooth until you have created the room required to move the malaligned teeth.
