Deep bite malocclusion correction with SmartForce Aligner Activation in three adolescent patients.

Area of Science:

• Orthodontics
• Dental Biomaterials

Background:

• Deep bite is a prevalent malocclusion in adolescents and adults, often challenging to treat with conventional clear aligners due to biting forces.
• Previous clear aligner (CA) treatments for severe deep bites faced limitations, often attributed to patient biting forces.
• Align Technology developed the SmartForce Aligner Activation protocol with specific CA features to enhance treatment predictability.

Purpose of the Study:

• To evaluate the skeletal and dentoalveolar outcomes of the SmartForce Aligner Activation Invisalign G8 protocol in adolescent patients with severe deep bites.
• To assess the effectiveness of a novel clear aligner activation strategy for deep bite correction.

Main Methods:

• The study involved three adolescent patients (2 female, 1 male, aged 11-14) with severe deep bites.
• Treatment utilized clear aligners with SmartForce Aligner Activation, worn 20/22 hours daily.
• Pre- and post-treatment records included intraoral/extraoral photos, orthopantomographies, and lateral teleradiographies, with a one-year follow-up.

Main Results:

• All patients achieved a Class I molar and canine relationship and flattened Spee curves post-treatment.
• Post-treatment teleradiography indicated significant skeletal, dental, and aesthetic improvements.
• One-year follow-up demonstrated the stability of the achieved orthodontic results.

Conclusions:

• The SmartForce Aligner Activation protocol appears effective for managing severe deep bites in growing orthodontic patients.
• This protocol offers a potentially predictable and successful treatment option for deep bite malocclusions using clear aligners.
