Greater control and improved clinical predictability — Invisalign G8 with SmartForce Aligner Activation is the newest series of biomechanical innovations for Invisalign treatment informed by tooth movements from millions of patients treated with Invisalign clear aligners.
Invisalign G8 is part of Align’s ongoing commitment to further enhance Invisalign as a force driven system. It focuses on improving deep bite, crowding and crossbite cases. These cases are improved by adding the Aligner Activation feature to aid in anterior intrusion for deep bite cases and posterior arch expansion for crowding and crossbite cases.
SmartForce features are even smarter
SmartForce Aligner Activation ensures areas on the aligner surfaces are contoured to apply forces to the tooth in the proper direction. Throughout every stage of treatment, the location, direction and intensity of the force work in harmony to create optimal force system unique to the patient (Fig. 1).
Predictable deep bite correction
Invisalign G8 improves clinical predictability of incisor intrusion in deep bite cases by up to two times1. Intrusion force levels are optimised for each tooth, and the precision bite ramps are clinically proven to improve lower incisor intrusion by up to 30%2 (Fig. 2).
Posterior arch expansion in crowding and crossbite cases
Automatically programmed to apply and distribute the required force to each posterior tooth, Invisalign G8 is designed to deliver more predictable posterior arch expansion for resolving crowding and crossbite cases (Fig. 3).
Reduction in the likelihood of posterior open bite
Invisalign G8 provides more predictable anterior intrusion, which may reduce premature anterior contacts – a common cause of posterior open bite. Invisalign G8 also controls unwanted buccal crown torque or tip during expansion which is another common cause of posterior open bite (Fig. 4).
