Reading and links
You can read this guide without entering information. It has no form, account, file upload or health-data submission feature.
Reading the pages
The static guide uses local assets. No added analytics, tracking script, remote font, embed or browser-storage feature is used. Reading does not require your history, contact details or photographs.
Ordinary website delivery may involve the hosting provider’s request processing and logs. This guide does not certify current retention arrangements or claim that no hosting processing occurs.
Choosing a practice link
The consultation link opens the existing SMILE-FX® website. Any information you voluntarily enter there is handled there under its applicable privacy information.
The three source tags identify this guide as the referring page. They are not proof of a received request, qualification, booking or assessment. Opening a destination is different from submitting its form or confirming an appointment.
The telephone link asks your device to open its calling function. Reading this guide does not place a call. Your device and telephone provider handle a call if you choose to make one.

SMILE-FX® simplified and reorganized selected author narrative and added the original text-led comparisons and completed interpretations. These are educational readings, not a patient case. No source figures, tables, captions, formulas, case material, direct third-party quotations or underlying-study expression are reproduced. Reference does not imply author endorsement. The applicable licence terms and warranty disclaimers remain; the licence covers adapted article material separately from practice marks and unrelated content.
This dated study used an observational convenience sample at one Invisalign® practice: 82 people aged 12–49 who completed the first set. It is not a controlled device comparison or a US norm. Detailed eligibility in Table 1 was not read or used. Wear uncertainty, nonuniform sampling and bite-recording error limit interpretation; static measures do not establish cause, chewing function, safety or personal recovery.
The stage labels are inconsistent: Methods describes T1 at goal completion, while Results uses it for the first-set group, including 54 who met the goals and 28 who did not. This guide uses the explicitly stated first-set comparison without treating all 82 as finished treatment. No full eligibility review, later-guidance review or named clinician review of this adaptation is claimed. Read the full guide scope.
