For many years lingual orthodontics was perceived as extremely complex and problematic, therefor it’s not widely used.

Kinju Fujita 1967 first introduced the mushroom shaped arch wire and practiced lingual orthodontics in 1971 for the treatment of class I and II cases with extraction of four bicuspids.

In the 1970’s when lingual orthodontics was first practiced, orthodontists used the traditional outside braces but placed them on the inside of the teeth. Unfortunately, this approach while it was a beginning had three main problems. The brackets tended to fall off, they were too bulky, and it was difficult to get as good a result as could be achieved with outside braces.


Why lingual orthodontics?


1. The aim of orthodontic treatment is to achieve a balance, or reasonable compromise, between:

·       Optimal occlusion and function.

·       Acceptable dento-facial esthetics and reasonable stability.

·       Considering the patient’s main complaint and their demands for short and esthetic orthodontic treatment.

Lingual orthodontics meets the patients requirement for esthetic orthodontic treatment and may be the shorter treatment course


2. Lingual orthodontics are useful for patients with susceptible enamel surface and patients with multiple vestibular surface caries




1. The biggest advantage of lingual braces is that they aren’t visible.

2. Lingual braces come in various designs. There are many types of bracket systems that these braces can have. This allows lingual braces manufacturers to come up with designs and bracket systems that would be helpful in specific cases.

3. Since lingual braces are placed on the inside, they don’t have to look unpleasant when they get stained or discolored.

4. There are many well-known brands of lingual braces and you can choose one that attends to your needs within a budget that you have present.



1. One of the biggest disadvantages of lingual braces is its cost. They are considerably more expensive than traditional metal or ceramic braces.

2. Lingual braces are extremely difficult to clean. You don’t get to see your braces so you don’t know how dirty they are or how stained they are.

3. Lingual braces can be very uncomfortable at the beginning. Once they are installed, they can be painful, they would severely impair speech and eating, the tongue would get sore and one may also find it unbearable.

4. Lingual braces take longer time to be placed, adjusted or cleaned.

5. Lingual braces don’t work very well in extremely complicated or severe misalignment problems.

6. There can be soreness in the tongue after lingual braces are placed.
