Hello

I have just got and hawley retainer with brakets and a headgear. (From the braces shop)

I have an overbite of 8mm, a deep bite, and  my uppermolars is not symmetric with my lower molars - The upper molars is forward of the lowers.


My questions is, is it possible to move my upper maxilla back, using this setup?
- Is it possible to reduce my deep bite, with a high pull headgear?
- If so, how much should I wear the headgear?

Happy to hear your thoughts, experience and ideas.

Yes, it probably is possible. But I wouldn’t do it. There is so high of a risk of doing it wrong and damaging your joints that it just won’t be worth it. This is exactly the sort of thing that ruins your life. If you want it fixed, you have to go to an orthodontist.

But again, yes, with extended wear, it is probably possible. It just isn’t smart.

Hi Bracesdk,

- Is it possible to reduce my deep bite, with a high pull headgear?

That definitely doesn't work! A high-pull headgear will make the deep bite even worse due to its pulling direction.
The force vectors intrude the molars of the upper jaw.


- If so, how much should I wear the headgear?

The high-pull headgear is unsuitable for your misalignment. Use it for fun, but not for medical purposes.

Greets,

I appreciate your answers!

I do not think that I will do it anyway, - but I like to work with the idea of how it could work.
Is quite interesting to see which method which could potential be considers in my case.

Would you suggest a cervical headgear instead? How much force would you apply?
What would be the ideal wear time?

Any other appliances that may be of potential?

All suggestions are welcome :-)

normally in your case a highpull headgear is used but only with medium force in growing jaws. I would also use midline elastics to correct the midline. And also brackets on all teeth with a specially bended bow for the lower jaw.

But ... this wont work with removeable plates and not on adults

As an adult, the possibilities of correction a deep bite with removables are very limited.
Theoretically, a classic activator could be used, but it would have to be constantly adjusted. the wearing time would then have to be 16 hours or more per day. this could cause the posterior teeth to elongate. But there is only little chance that it would work.

A cervical headgear would work better. It can extrude the molars if it is inserted directly into metal bands. Use max. 200 grams of force. However, fixed braces would then also have to be inserted.
Other modern methods are, for example, appliances that are anchored to mini-pins in the bone in the upper jaw. These can extrude the posterior teeth and intrude the anterior teeth. However, this is definitely not something you should do yourself with a battery-operated screwdriver.  ;D

Great information! - Would you be using 200g force for how much time?

The force of 200g is only indicated if the entire dental arch is fitted with brackets. Then you can extrude with 100g per side. This is already too much for a single tooth. Extrusion increases the risk of nerve damage to the affected tooth. I personally consider the headgear to be unsuitable for self-experimentation.

For all tooth movements: The longer the wearing time per day, the better. Studies show that tooth movement can occur from as little as 8 hours a day. In adulthood, it has to be a little longer because there is no more bone growth. The maximum movement of a tooth through the bone is determined by the turn-over rate of the osteoclasts and is approx. 1.8 mm per month. Higher forces generally lead to damage to the tooth roots.
