INFORMED CONSENT AND AGREEMENT FOR THE INVISALIGN PATIENT 1 of 3
Patient’s Informed Consent and
Agreement Regarding Invisalign®
Your doctor has recommended the Invisalign® system for your
orthodontic treatment. Although orthodontic treatment can
lead to a healthier and more attractive smile, you should also
be aware that any orthodontic treatment (including orthodontic
treatment with Invisalign aligners) has limitations and potential
risks that you should consider before undergoing treatment.
Invisalign® aligners, developed by Align Technology, Inc.
(“Align”) consist of a series of clear plastic, removable
appliances that move your teeth in small increments. Invisalign
products combine your doctor’s diagnosis and prescription
with sophisticated computer graphics technology to develop a
treatment plan which specifies the desired movements of your
teeth during the course of your treatment. Upon approval of a
treatment plan developed by your doctor, a series of customized
Invisalign aligners is produced specifically for your treatment.
You may undergo a routine orthodontic pre-treatment
examination including radiographs (x-rays) and photographs.
Your doctor will take impressions or intra-oral scans of your teeth
and send them along with a prescription to the Align laboratory.
Align technicians will follow your doctor’s prescription to create
a ClinCheck® software model of your prescribed treatment. Upon
approval of the ClinCheck treatment plan by your doctor, Align
will produce and ship a series of customized aligners to your
doctor. The total number of aligners will vary depending on the
complexity of your malocclusion and the doctor’s treatment plan.
The aligners will be individually numbered and will be dispensed
to you by your doctor with specific instructions for use. Unless
otherwise instructed by your doctor, you should wear your
aligners for approximately 20 to 22 hours per day, removing them
only to eat, brush and floss. As directed by your doctor, you will
switch to the next aligner in the series every two to three weeks.
Treatment duration varies depending on the complexity of your
doctor’s prescription. Unless instructed otherwise, you should
follow up with your doctor at a minimum of every 6 to 8 weeks.
Some patients may require bonded aesthetic attachments
and/or the use of elastics during treatment to facilitate specific
orthodontic movements. Patients may require additional
impressions, or intra-oral scans, and/or refinement aligners
after the initial series of aligners.
• Invisalign® aligners offer an esthetic alternative to conventional
• Aligners are nearly invisible so many people won’t realize you
are in treatment.
• Treatment plans can be visualized through the ClinCheck®
• Aligners allow for normal brushing and flossing tasks that are
generally impaired by conventional braces.
• Aligners do not have the metal wires or brackets associated
with conventional braces.
• The wearing of aligners may improve oral hygiene habits
• Invisalign patients may notice improved periodontal (gum)
health during treatment.
Risks and Inconveniences
Like other orthodontic treatments, the use of Invisalign®
product(s) may involve some of the risks outlined below:
(i) Failure to wear the appliances for the required number of
hours per day, not using the product as directed by your doctor,
missing appointments, and erupting or atypically shaped teeth
can lengthen the treatment time and affect the ability to achieve
the desired results;
(ii) Dental tenderness may be experienced after switching to the
next aligner in the series;
(iii) Gums, cheeks and lips may be scratched or irritated;
(iv) Teeth may shift position after treatment. Consistent wearing
of retainers at the end of treatment should reduce this tendency;
(v) Tooth decay, periodontal disease, inflammation of the
gums or permanent markings (e.g. decalcification) may occur if
patients consume foods or beverages containing sugar, do not
brush and floss their teeth properly before wearing the Invisalign
products, or do not use proper oral hygiene and preventative
(vi) The aligners may temporarily affect speech and may result in
a lisp, although any speech impediment caused by the Invisalign
products should disappear within one or two weeks;
(vii) Aligners may cause a temporary increase in salivation or
mouth dryness and certain medications can heighten this effect;
