What are Invisalign® Express and Teen? -

Differences and similarities to standard Invisalign®. | System details. | Applications.

Align Technology, Inc. offers two variations of their standard Invisalign® program. They are the Express and Teen systems.

Each of these alternatives allows the dentist more flexibility in accommodating the unique treatment needs of specific groups of patients.

Invisalign® Express

The Express program makes it possible for a dentist to treat relatively minor orthodontic cases for a lower fee.

Instead of the standard 20 or 30 sets of aligners, this system only involves the use of 10 or fewer, which reduces the dentist's overhead costs.

(See the chart below for further comparisons between Express and standard Invisalign®.)

a) What kinds of cases can Express treat?

Invisalign® Express is most suited for treating relatively simple cases. This would include those involving minor tooth crowding or rotations, and small midline corrections (teeth aligned off-center). Some common applications include:

  • Correcting minor alignment issues for front teeth.
  • Correcting relapse that has occurred following previous orthodontic treatment (like that caused by the patient not wearing their retainers).
  • Making minor alignment changes in preparation for other dental work, such as placing veneers.

b) Alternatives to Express®.

There are competing clear-aligner systems that can be used to treat many of these same types of cases. One of them is Simpli 5®.

Invisalign® Teen

The Teen program offers all of the features of the standard Invisalign® system plus some additional ones that assist the dentist in dealing with situations or problems unique to treating younger patients.

a) When is it used?

Invisalign Teen® is intended for use with "less dentally mature" patients. This means those children who have lost their baby teeth but their permanent teeth have not yet fully erupted.
The issue.

Much of the difficulty associated with treating younger children with Invisalign® has to do with managing their permanent teeth as they come into place during the treatment process.

With this in mind, Teen has been designed to accommodate the incomplete (progressing) eruption of second molars, canines (eyeteeth) and second premolars. (Malik 2013) [page references]

b) What age group is Teen used with?

The transitional period described above can take place at a different age with different children.

  • The last of a child's baby teeth usually fall out between ages 10 and 12.
  • The 2nd molars have usually come into place by age 12 to 14.
  • This places the treatment time window for Teen somewhere between 10 and 14 years.


c) What's special about Invisalign® Teen?

Teen includes all of the features of standard Invisalign®. But it's different due to the fact that compensation for tooth eruption is factored into the treatment.

It also includes an allowance for the replacement of up to 6 lost or damaged aligners, something that might be important in treating patients in this age group.

A comparison of applications for Invisalign® Express, Teen and standard.

This next comparison table shows that each system can be used to treat a similar range of conditions. But because Express involves the use of fewer aligners (see above), the total amount of tooth movement that can be accomplished with it is less.
