Align Technology launches Invisalign G4

Align Technology has introduced Invisalign G4, designed to help doctors achieve better clinical results for open bite treatments, more predictable movement of upper laterals, and improved root control for canines and central incisors.

"Invisalign G4 expands on the Invisalign G3 foundation which first introduced new aligner and software features that make it easier to use Invisalign when treating class I and class II patients," stated Sheila Tan, Align Technology's vice president of marketing and chief marketing officer, in a press release.

New Invisalign G4 features are engineered to help doctors achieve the following:

• Better clinical outcomes for open bites: New multitooth approach for open bite treatment and improved optimized extrusion attachments are designed to improve clinical outcomes when treating anterior open bites.
• Improved predictability for upper laterals: New optimized multiplane movement features are designed to improve control of upper laterals undergoing extrusion along with rotation and/or crown tip.
• Greater root control for canines and central incisors: New optimized root control attachments provide greater mesio-distal root control for canines and central incisors.

In addition, optimized extrusion attachments for anterior teeth have been improved to better deliver the force needed for great finishes, and optimized attachments that were introduced with Invisalign G3 can now be used in conjunction with precision cuts, where applicable, when treating class II and class III patients with Invisalign, according to Align.

The expanded Invisalign G4 product features will be available on Invisalign Full, Invisalign Teen, Invisalign Assist, Invisalign Express 10 (previously Invisalign Express), and Invisalign Lite at no additional cost to Invisalign-trained doctors worldwide starting November 14, 2011.
