Mouthpiece Orthodontics


With Invisalign and Aso Aligner just being two types of orthodontics with a proven track record, we offer the best orthodontic solutions for our patients! We at Toranomon Hills Dental-Medical Ryu Clinic are here to help you with any concerns you may have about your dental health and teeth!

First of all

In recent years, mouthpiece orthodontics has gained a lot of attention as a way to straighten teeth. There are two main types of aligners: Invisalign and Aso Aligner. Both methods involve wearing a clear mouthpiece to move teeth, but each has its own characteristics.

What is invisalign?

invisalign is a mouthpiece orthodontic system developed by Align Technology, Inc. in the United States. It is the most popular mouthpiece orthodontic system in the world, and its main feature is that it is less noticeable when worn due to the use of a highly transparent mouthpiece.

Pros of invisalign

・High transparency of the mouthpiece makes it less noticeable
・The mouthpiece is comfortable to wear and does not use brackets or wires
・Relatively short treatment time

Cons of invisalign

・Relatively high treatment cost
It takes time to start treatment because a dental mold must be sent to the USA before treatment can begin

What is Aso Aligner

Aso Aligner is a mouthpiece orthodontic system developed by the Japanese company Assoa. Similar to invisalign, it is a method of moving teeth by wearing a transparent mouthpiece, but Aso Aligner tends to be less expensive than invisalign.

Pros of Aso Aligner

・More affordable compared to invisalign
・As with invisalign, the highly transparent mouthpiece is less noticeable
・The mouthpiece is comfortable to wear without brackets or wires

Cons of Aso Aligner

・Treatment time can be longer than invisalign
・Failure to adhere to wearing time will make the alignment less effective

Which is right for you?

Invisalign and Aso Aligner are both clear aligner systems, but each has its own characteristics.


Invisalign is recommended for:

・Patients who value a discreet appearance
・Patients who want to shorten the treatment time

Aso Aligner is recommended for:

・Patients who want to keep costs down
・Patients who want to have a Made in Japan aligner

Which one is right for you depends on your own wishes and conditions. First of all, you should have a consultation at the dentist’s office to choose the treatment that best suits your situation.
