Correction of Lower Tooth Supraeruption Part II

On Oct 29, 2013, #28/29 lingual mini implant lost again.  After oral consent, brackets were placed on the teeth #27-30 : #27 5 mm from cusp tip, 28,29: 3.5 mm, #30 lower than #29's.  A segmental wire: 14 niti was placed.  It has a feature of roller coaster.  Power chains x2 were placed between  #28/anterior mini implant  (Fig.4).

When the patient occluded, the upper canine contacted (Fig.5 arrow) the bracket on the lower 1st premolar.

Composite was added to the occlusal surface of the molars.  There was clearance (Fig.6).

What would happen with limited ortho apparatus (Fig.4-6) in one month?
