CCO Case File: Class III Non-Extraction/Female 13.6 yrs.
Author: Dr. Antonino Secchi
13:6 yo Female with a Pseudo Class III malocclusion. Her vertical as well as her transverse dimension were normal. It is important to notice the distal tip of her upper canines, the uneven maxillary occlusal plane and the spaces behind the canines in the lower arch.
Tx Strategy by Stages:
Stage I: Leveling and aligning, correct all rotations and obtain normal tipping of upper canines.
Stage II: Coordinate upper and lower arches, level maxillary occlusal plane, close lower spaces using Sentalloy coils and short Class III elastics. Normalize OJ/OB relationship.
Stage III: Achieve optimal intercuspation of the buccal segment using vertical triangular elastics.

Stage II. Upper and lower 0.019” x 0.025” ss. AccuForm Medium wires. Wires must be coordinated before placement. Build ups on lower molars using blue compomer to open the bite. Short Class III elastics 3/16” 6oz are introduced at night time.
Stage II. Upper and lower 0.019” x 0.025” ss. AccuForm Medium wires. Notice how the upper archwire is now completely leveled. Lower Sentalloy coils (150 gr) and Class III elastics (night time), to close spaces.
Stage II. Upper and lower 0.019” x 0.025” ss. AccuForm Medium wires. Upper and lower occlusal planes leveled and paralleled. Finishing space closure. Power Chain is used to consolidate spaces. Vertical triangular elastics 3/16” 6oz.
