Patient Chief Concern
Anterior crossbite, crowding of upper incisors.

What learning would you share with other Invisalign providers?
In Class III patients with overclosure, a functional shift of the mandible occurs once bite jumping is achieved, allowing additional Class III correction to be expected. In the present case, despite the patient being an adult, a bite jump resulting from posterior repositioning of the mandible occurred early in treatment under the influence of Class III elastics. This may have been further facilitated by the inherent characteristic of Invisalign clear aligners, which cover the occlusal surfaces and thereby disocclude the dentition.

What contributed most to this treatment being successful?
The success of this treatment was primarily attributed to two factors: the use of Class III elastics to induce bite jumping, and sequential distalization in the mandibular right quadrant to address the more severe Class III relationship on the right side.

Clinical Indications

Anterior crossbite
Class III
Crowding
Deep bite
Mandibular midline deviation
Rotations
Spacing

As the Class III relationship was more severe on the right side, sequential distalization was applied in the mandibular right quadrant to achieve a greater amount of Class III molar correction.

Modalities

Distalization
Elastics: Class III
Intrusion
IPR
Leveling Curve of Spee

Since both the deep bite and the anterior crossbite had to be resolved simultaneously, intrusion of the mandibular incisors and Class III elastics were initiated in the early phase of treatment.
