CASE REVIEW: Class III Skeletal Open Bite Treated Without Surgery10 MONTHS/5TH VISIT 11 MONTHS/6TH VISIT10 MONTHS/5TH VISITThe .017 x .025 low-friction (purple) TMA archwires had been engaged for 5 weeks with a changein the elastics configuration at 9 months (CL III tendency on the right side), then back to a triangleconfiguration, bilaterally at this juncture.11 MONTHS/6TH VISIT — Rotation Wedges EmployedThe TMA archwires had been engaged for 9 weeks at this juncture and the elastics were placed in adouble finishing configuration. The reduced widths of DQ brackets—while increasing the interbracketdistances that further reduce the already light forces that PSL applies—also reduce rotational controlin the upper incisors. This reduced control can sometimes warrant using rotation wedges (for smallrotations) or placing finishing wire bends (for more severe rotations).22 vol. 19 | no. 01 | february 2013 ormco.com/ci
