SR Case Advice

tricky one in that removing lower 4's will create too much space

LR canine is in good relation with upper..... could consider ext LL4 only and help swing the lower CL to the left

So options

Ext LL4 and Lower fixed and upper aligners

or

Accept buccal LL4 and upper and lower aligners with IPR lower as needed - but the LL4 will remain wheres it is

Hope that helps

Ian,
Another case for your advice if that's ok...

Pt C/O: had fixed upper ortho but no lower as a teen, wore a retainer for 1 year and then had fixed so was told didn’t need removable. Fixed repeatedly broke and was repaired. Now gaps LHS and crowding. Concerned about further relapse. Mostly concerned about gaps and anterior aesthetics including wear on centrals. No occlusal concerns.
Summary of findings:
Skeletal 1 with class 3 incisors (almost edge to edge), LAFH slight increase, NLA normal
Crowding v mild upper, mod lower 5-5
OJ reduced, OB reduced
Buccal segments full unit 2 RHS, 3 / 4 unit 2 LHS
Canines class 1
Problem list: space UL2 LL2, mod lower crowding, class 3 incisors with unstable buccal segment LHS

Aims of tx: relief of crowding, align, level, class 1 incisors, class 2 molars, space closure
Tx plan:
XLA LR4LL4
Fixed U/L

Could upper be done on aligners and lower on fixed?
