A new provisional (Fig.2,3) co-incides with the facial midline. Brackets will be placed between UR4 to UL3 except UL2 (symptomatic once with chronic periodontitis) with initial proximal reduction between UR1-4 in preparation to correct cross bite of UR2. Severe buccal plate atrophy at UL1 should have been prevented by block graft or Titanium mesh.
