SmartForce features and s. Designed to help you treat with confidence.
SmartForce features and s. SmartForce Features are: Engineered to deliver the force systems necessary to achieve more predictable tooth movements. Customised to each tooth using advanced virtual modeling, including such features as the width, long axis, and contour of the entire tooth. Positioned more precisely to deliver the necessary forces while eliminating interferences. SmartForce features are automatically placed in accordance to the desired movement. 1
SmartForce features - overview. Feature Movement Available on Visual Buccal Power Ridge Lingual root torque Upper and lower incisors May November Buccal Power Ridge + Lingual Power Ridge Lingual root torque and retraction Upper incisors Rotation Rotation Upper and lower canines and premolars Extrusion Extrusion Upper and lower incisors and canines Multi tooth anterior ExtrusionUpper incisors Root Control Tipping Upper central and lateral incisors Upper and lower canines and premolars Multi-plane Movement features Extrusion ± crown tipping ± rotation Upper lateral incisors Deep Bite s During anterior intrusion, Deep Bite s are used for anchorage/retention or activated for premolar Upper and lower premolars Pressure Areas Anterior intrusion Incisors and lower canines Precision Bite Ramps (are not SmartForce features per se, but can be prescribed by the Provider, and are placed depending on compatibility with other features). Disocclude the posterior teeth Upper incisors Retraction Canine retraction Upper and lower canines Multi-Tooth Unit Anchorage Posterior anchorage Upper and lower second premolars and molars Note: variation in type of attachment, or variation of attachment placement can occur for short crowns. 2

The default protocols described in this document are used to create the initial ClinCheck treatment plan, based on the Invisalign Provider s prescription. However, the final treatment plan remains the responsibility of the Invisalign Provider and should be reviewed carefully and modified as necessary before the ClinCheck treatment plan is approved. 2. Do not apply forces, but re-direct forces applied by aligner to improve intrusion predictability. 3
Conventional attachments. The table below shows conventional attachments that can be prescribed in addition or in lieu to any other attachment or SmartForce feature placed by default (depending on compatibility). Ellipsoid Rectangular Rectangular beveled 0.5 mm 3 mm 3 mm, 4 mm, 5 mm 2 mm 3, 4, 5 mm 2 mm 1 mm 2 mm 1 mm 1.25 mm Default sizes for conventional attachments: Ellipsoid horizontal, ellipsoid vertical: 3 mm height, 2 mm width, 1 mm prominence. Rectangular horizontal, rectangular vertical: 3, 4, or 5 mm height, 2 mm width, 1 mm prominence. Rectangular beveled horizontal incisal, rectangular beveled horizontal gingival, rectangular beveled vertical distal, rectangular beveled vertical mesial: 3, 4, or 5 mm height, 2 mm width, 0.5-1.25 mm prominence. Conventional attachments can be placed directly on the 3-D model by dragging/dropping to the desired tooth, and removed (as for the s) by dragging them to the trashcan. With ClinCheck Pro, their placement can be adjusted and they can be rotated for higher control on the position. Conventional rectangular attachments can also be adjusted for prominence and degree of beveling. 4
Conventional attachments - default protocols. 1 For certain Invisalign treatments conventional attachments will be placed by default. Some of these default protocols combine conventional attachments with SmartForce features ( s). The table below shows the Invisalign default protocols in which conventional attachments are placed, unless otherwise specified in clinical preferences or in the prescription form for a specific patient. Movement Default protocol 1 Example Space closure lower incisor extraction Vertical rectangular 1 mm thick conventional attachment on the two teeth adjacent to the extraction space Space closure First premolar extraction not planned for maximum anchorage (or more than 2 mm mesial crown posterior movement) or conventional attachments (depending on the movement) on the canine and premolar, and 1 mm thick conventional attachment on the molar Second premolar extraction Aligner retention 2 ATTACHMENTS NOT OFFERED BY DEFAULTpremolars For more details on SmartForce features, please visit learn.invisalign.com/treatmentoptions/innovations 1.

Note about aligner retentiveness: Providers may request attachments when aligner retentiveness is a concern. 5
