Treatment

Objectives. Close maxillary spacing, use Forsus to posture the mandible forward and produce dentoalveolar changes to improve the Class II relationship, reduce overjet and protrusion, level and align both arches, coordinate the midlines, and improve the facial profile.

Plan. Band the upper first molars and bond 7–7. Level and align both arches, then use the Forsus appliance as the Class II corrector to advance the lower dentition and improve the Class II relationship.

Appliances and materials

  • Metal Braces — 022 MBT
  • Class II Forsus
  • Class II elastics

Outcome

We successfully leveled and aligned both arches and corrected the Class II malocclusion to a Class I relationship. Treatment was completed with an ideal 2 mm overjet and 2 mm overbite, with well-coordinated dental midlines. The mandibular incisors were well controlled and maintained in an ideal position. Favorable forward mandibular growth contributed to the Class II correction, with skeletal improvement demonstrated by the Wits appraisal and ANB angle. Her facial profile became more balanced, with improved facial esthetics both at rest and on smiling. Overall, treatment achieved a well-coordinated Class I occlusion, ideal overjet and overbite, improved skeletal relationship, and enhanced facial and smile esthetics.

Retention
