Why are Dental Handpieces Air Driven?

Why are Dental Handpieces Air Driven? I"ve always wondered that. The snake's nest of little airtubes inside a dental chair is a always a mess (to me anyways). Here, Rejean explains why they were air driven - and - why it's time to go electric.

The most benfits of electric handpieces is low sound coming out of it as most patient got afraid of this sound and also noisy, but i think electric hand pieces more expensive and gonna need more maintainance,, thanx for the video

[@AllThingsDentistry]

mohamed hassan let me record the sound. Good point. I didn’t even think aboit that

[@traceymurphy4804]

True, it's quieter but I love the torque and ability to change direction of spin and speed of the byr

I wouldn't say that's the best but it's definitely less annoying to me. I wear earplugs anyway.

[@traceymurphy4804]

I have both and love my electric. The 2 other dentists in my office prefer the air, but I think it's because the weight and size of the electric is bigger and takes time to get used to

[@mrMasterXx]

My experience is that the air rotor generally has less weight, it's much easier to control and doesn't hurt my hand as much after a long day comparing to micro-motor handpiece.

[@crazyabtdance26]

agree about the weight! I can't use electric handpiece for long. Not sure if it's just the brand of electric handpiece I am using. If you have recommendations for electric handpiece, please let me know =)

Electric high-speed handpieces are not very common where I practice (India). Most dentists use air-driven ones for restorative work. There is also something we call a micro-motor handpiece which is used for polishing but it does not have an incorporated water spray and is not very efficient for drilling. How does the water spray system in the motors shown in the video work? Is it all-electric or the water is air driven and the motor itself electric?

[@mohamadmostafa8826]

in Egypt we use an adapter so you can use it directly from the dental unit without using the micro-motor.

[@AllThingsDentistry]

Thanks to Rejean for explaining why these things are air driven. The next series of videos, he'll talk about gear ratios. #dentistrygeeks . LOL

[@joelakin1]

Fascinating video. Really interesting to hear some of the history.

[@AllThingsDentistry]

I have a few more videos I should upload from him. He’s great!

[@erikak8187]

what about old motors for strait hand piece, rotary tool

[@erikak8187]

One of my closest friends who is a dental assistant. The hand piece equipment was ran by a compressor

[@sila8219]

Can you use this for endo , like preparing canals with files ? Would like to see video on that
Thank you

[@guilhermesada5840]

Thanks for the video.

[@AbsoluteXero]

I really like how forward thinking bien air is. Even if there is a problem with the app, it should be easy to fix by software. Then again, it sucks relying on a proprietary hardware like an ipod. If only bien air could come up with their own hardware for touchscreen that'd be perfect haha

[@kkou01]

But what about the big compressor at the back. If the office goes all electric could u go with a smaller compressor. I’m sure electric will will be all the rage when u don’t need the compressor at all. One day maybe.

[@AllThingsDentistry]

We have the choice of electric or air. I can tell you that using electric is the way to go. Unlimited torque in a high speed means that I can prep a crown efficiently without having to brush. I can also slow the high speed down (diamonds) to an exact RPM to finish margins - for example - from 200k down to 50k. It's amazing and I'm grateful for the opportunity to use electric.

[@ray47778]

Can you please contact me regarding buying these motors

[@gauravvij67]

Bien air make good electric motors. I run one chair and the motor has lasted 5 years full time.
But electric handpieces are expensive, have expensive maintaince , are heavy, can cause burns, have the wrong shape and are unergonomic. I've used Chinese sandent high torque turbines for 10 years with quick release burs and exchangable 20 dollar cartridges and can tell no difference between these and high end brands in utility value.
The bien air electric reduction handpieces would have to compete with a 40 buck handpiece for them to be viable economically.
