As the market-leading clear aligner system, Invisalign is planned digitally from start to finish before a single tray is made. It is available from a number of certified providers in and around Slack. You can usually preview a 3D simulation of your finished result before treatment is even approved.
Choosing an Invisalign Provider in Slack
Align Technology grades certified providers by annual case volume — Provider, Preferred, Elite and Diamond. Higher tiers have treated more cases and tend to be more comfortable with complex situations, so asking a Slack provider about their tier is a useful starting point.
When comparing providers, confirm whether the fee includes refinements and retainers, what scanning technology they use, and how often they review progress — each affects both outcome and total cost.
The Technology Behind Invisalign
SmartTrack material is Align's own aligner polymer, built to keep force consistent from day one to day fourteen of each tray and to fit more snugly than generic materials.
ClinCheck software builds a 3D model of your teeth and maps every stage of movement, letting you preview the expected result before treatment starts. Your clinician reviews and refines the plan before any trays are made.
iTero scanning does away with physical impressions — a quick digital scan builds the 3D model, feeds ClinCheck, and monitors tracking at each review. It's routine among Slack providers.
Attachments are the small bonded bumps that let aligners grip and control harder movements. They're tooth-coloured, removed at the end, and used in the majority of cases.
