Fraenkel activators
« on: 05. July 2022, 18:40:11 PM »
Hi all
I have never seen a Fraenkel Actovator in person.
I often wonder how it is in the mouth.
Does it clasp to uper (or lower) teeth or it stays somehow free in the mouth?
I mean, when you open the mouth, it is free to move inside ot it stays on the upper jaw like a retainer does?

Thanks fo an answer, and maybe a link to a video, if possible.

Hi Milva,

Please see this link to a nice video regarding Fraenkel Activator. If you have further questions I can give you some more information, because I was wearing a Fraenkel appliance some time ago:

Thanks for the link.
The video is really interesting.

From the video and the underwritten notes I understand that the Frankel Appliances

1) are used on very young patients and not on adults
2) are loose in mouth, not they do not clasp on the upper jaw, so thaqt when you open mouth fro example for speaking they move inside the mouth
3) are worn FULL TIME for a long time

They are BIG and fill the mouth, also because they are somehow "elastic"

It definetely looks like one of the most impressive appliances ever! Maybe more or lesso like a twinblock!

It is pretty noticeable also with your lips shut, because they give youa sort of "squirrel loook" with ceeks full.

Despite the fact that they are inappropriate on adults, I'm curious to find how it feels inside my mouth!


I really cannot imagine how can you speak with it inside

No, also for teenth and in exceptional cases for adults (not for active treatment, but for retention). I myself got the first function regulator as schoolboy at 14 or 15 years. The second one I had to wear as adult during second treatment as retention appliance for training of the face muscels.

2) are loose in mouth, not they do not clasp on the upper jaw, so thaqt when you open mouth fro example for speaking they move inside the mouth
Yes, it is not fixed at the teeth.

3) are worn FULL TIME for a long time
Yes, the appliance has to be worn full time (24h per day / 7 days per week) and should be removed only for eating and sport activities.

They are BIG and fill the mouth, also because they are somehow "elastic"
The large plastic parts are between teeth and cheeks, so there are only wires and little plastic parts in connection with the tongue.

Speaking is not a large problem with the appliance inside, but you have to learn to speak without big movements of the jaws. The teeth have to be nearly closed during speaking. Therefore some training is required, but after this there is no problem.

I had a classmate in school who got a Fraenkel. It was exactly at the time I had to wear a Bionator, so we compared our devices. His Fraenkel was so huge, but he was able to talk much more easy than me with the device in the mouth. This is because there is much less on the mouth´s roof to be able to talk better. Wearing it is similar to a Bionator, you need to bite actively in, but it will not latch into the teeth.

They are used on adults some.  There is one orthodontist in Ohio who uses them a lot.  For TMJ cases he will start the patient out in a removable bite splint.  Then after 6-12 months he will transition them to a Frankel which is supposed to be worn full time except when eating/hygiene.  Then after about 6 months he will move them into braces with lingual arches and elastics.  He continues to have them wear the Frankel at night and lip tape to keep the appliance in place.  Now that really is a mouthful.

1) are used on very young patients and not on adults

That is correct. the appliance is intended to stimulate bone growth. So treatment is hardly possible for boys from the age of 14 and girls from the age of 12.

2) are loose in mouth, not they do not clasp on the upper jaw, so thaqt when you open mouth fro example for speaking they move inside the mouth

exactly. the appliance lies loosely in the mouth and holds the cheeks and lips in place. This causes traction on the periosteum and the bone builds up.

3) are worn FULL TIME for a long time

The more wearing time the patient achieves, the better. Speech is only slightly restricted.
