What learning would you share with other Invisalign providers?
Invisalign Treatment with mandibular advancement featuring occlusal blocks is a very efficient and successful treatment modality to address Class II teenage patients

What contributed most to this treatment being successful?
The patient’s Class II skeletal malocclusion was successfully corrected to Class I using the Invisalign® System with mandibular advancement featuring occlusal blocks. The severe deep bite and excessive overjet were also corrected to an ideal. The patient’s cooperation was excellent throughout treatment.

Clinical Indications

Class II div 1
Increased overjet

Class II skeletal patient, retrognathic mandible with good projection of pogonion (convex profile), proclined upper incisors, canine and molar relation left side: full Class II, canine and molar relation right side: full Class II, overbite: 5.5 mm, overjet: 8mm, both dental arches presented mild crowding, coinciding dental midlines

Modalities

Since the patient is still growing, the treatment plan options include conventional twin blocks or the Invisalign System with mandibular advancement featuring occlusal blocks. The preferred option was with Invisalign treatment, as it offers the possibility of correcting the anteroposterior (AP) condition while simultaneously leveling and aligning the rest of the dentition.

Summary

The patient’s Class II skeletal malocclusion was successfully corrected to Class I using the Invisalign occlusal blocks. The severe deep bite and excessive overjet were also corrected to an ideal. The patient’s cooperation was excellent throughout treatment. After the MA-phase was completed, a new scan was taken for additional aligners. The remaining open bite from the MA phase was resolved by using vertical and Class II elastics on an additional aligner order.
