Dental chair corrosion

[gtidriver]

Not sure where to put this thread but here we go. Calling all Dentist/oral hygienist .. does anyone have an Ancar dental chair and if so have you suffered with corrosion issues?? mainly in the area of the spittoon and the water dispenser. Many thanks.

I'll wager its galvanic corrosion between aluminium and possibly stainless? The only cure is to isolate the two metals effectively. Something like epoxy primer.

Cheers MW,I thinking its powder coated alloy but poorly applied.It has a dusty white look when the corrosion is revealed, We also have a 13 year old Ancar chair with no corrosion at all. Sign of the times, charge more but do less..

So, go on, how much does some of these things cost? Not cheap, I imagine.

[gtidriver]

I think the last one I bought was around £23000, but a knee brake or bariatric chair is a lot more. Plus all the extras, monitor camera etc, you could get into the £40000 price bracket.

About £230.00

And it suffers from corrosion?!

I initially thought ancar were Italian, but they are Spanish - they all rust like that sir!

And if you really want a laugh, try to find a poor implantologist.

Just as an aside, it is scary how much money is involved in dentistry, every year there is a show held alternately between the NEC and the Excel, the first time i went was in 2016 at the Excel and the sheer amount of finance being taken out was staggering but equally, the cost involved in some of the stuff for sale is mind blowing.

Aircraft costing millions also corrode.

If you buy a dentist chair from solid gold it should be ok.

The OP has stated he has a 13 year old chair without corrosion, which would suggest the newer chairs should also be capable of not corroding.

At that kind of price I don’t think he is wrong to think they should be able to withstand the chemicals/usage a dentist is likely to put them to and last a considerable time without corroding.

I agree with the OP, its astounding how much these companies extract from your wallet, while providing poor products.
The industry is rotten to the core.

There is a product called duralac which is designed to form a barrier between materials that create galvanic corrosion. You would need to judge for yourself whether you could have it potentially come in to contact with customers depending on its location although I don't believe it's especially harmful. The corroded part would clean up and recoat easily enough if it is removable. If it isn't easily removable and the design allows you could clean the corroded area up thoroughly, and make a neat piece of self adhesive vinyl and cover it. Then bolt the spittoon back down, the vinyl hopefully protecting the bare alloy from future corrosion.

Perhaps the OP has been kidnapped and this is code? Shall we send in Arnie?

I'm just going to nip out of the room while we take the x-ray. I'll be back.

I think it's quite nasty stuff, though, not sure if it would be considered appropriate in a clinical setting?

What a brilliant thread. Who knew this was even 'a thing'?
