9/19/2017 I'd consider closed eruption followed by a ballista spring in a continuous .018 SS wire with a disto-palatal and occlusal vector and then complete the alignment with a cantilever if needed. ■ Fenrisúlfr Member Since: 02/25/09 Post: 2 of 11 9/19/2017 Two thoughts: One: What was the original plan with the patient? Don't know where the UL3 originally was, but did you ever think about putting the UL4 in the UL3 position and the UL4 in the UL3 position? How long have you been in braces? Why hasn't the tooth already been uncovered? Two: On the palate, I like to do open eruption uncovering with a chain attached. I would do that and PT back to the UL6 or place a TPA/Nance to pull back to. A TAD would work great as you mentioned. ■ fesdds Member Since: 05/22/08 Post: 3 of 11 9/19/2017 Open coil spring and gradual eruption and substitution of the bicuspid for the cuspid. ■ 9/19/2017 A good question. This is a transfer patient from another doctor and unfortunately, I have no initial records of the patient. These are the records I made. But, given that the root apex of the bicuspid is distal to the canine, I am more inclined to the option of positioning the bicuspid in its place. ■ danbraces Member Since: 11/09/08 Post: 4 of 11 3Mortho Member Since: 11/18/07 Post: 5 of 11 9/19/2017 I agree with danbraces. Attempting to resolve the transposition is very challenging. This is a difficult impaction anyway. I think the only chance for retrieval is substitution. ■ lewbsample Member Since: 10/24/11 Post: 6 of 11 9/20/2017 I guess there are transpositions and transpositions. This one, the apex of the premolar is way distal so to me this is more a horizontal impaction type of transposition. I think I would attempt to move this premolar into its proper position by moving it away from the roots and distally.
