Changing O-Rings on Overdenture?

Helen, a dental implant patient, asks:

I have two lower dental implants with ball attachments. The overdenture seems to fit fine and is retentive and comfortable. The problem is that my dentist has to change the O rings every 2 months and he charges me every time he changes them. Is there any way for me to buy the O rings and bulk and then change them myself? What are my other options?

I have a patien who has had a similar overdenture for almost 20 years. Her husband took an o- ring to an hydraulic cylinder supplier and they matched the o-ring. She can get a dozen or so for a few dollars. She is very diligent in seeing me for an annual cancer screening, or any percieved trouble. Another consideration is to trade out the o-ring retention for locator attachments that tend to last longer and have variable levels of retention

I encourage my patients to try to do so and supply them with a few o-rings to get started although a two month interval in my experience seems a bit frequent. Regardless, you can consider attempting to purchase online from "attachments international" based in California in the SF area. Although they likely only sell products to dentists, "don't ask, don't tell" will probably work. Good luck. And a final note: it can be a little triky to change these. A small instrument, like a dental explorer, to remove the old ones, and a bit of lubrication like vaseline to help with insertion of the new.

First of all the dentist should charge you when he changes the o rings. Would you expect anything less from any other professional service you receive? Second of all and more importantly if you're going through the o rings every 2 months you most probably need to have the overdenture relined.That's why the o rings are getting chewed up. Third ,if possible the locator is a MUCH better attachment.If you can upgrade it will be well worth it.Good Luck.

I agree that dentists should charge for o ring replacement, on the other hand my wife's dentist charges her $250.00 to change 4 o rings, which takes all of 10 minutes. Is it a wonder I'm going to start doing it myself. Total robbery for sure. If you figure how much he would make in an hour changing o rings it would come out to $1500.00 . One week's wages for the average worker.A dentistry licence should not be a licence to abuse the folks that don't possess the skill or the ability to change their own. A price governing group is badly needed in the dentistry profession. Cheers , Jacques Morneault.

The Mini implants are not convertible to Locator abutments. Some of the o-ring manufacturers, The OSO o-ring for example wears way faster than those by Imtec or OCO Biomedical. If the patient has a dry mouth, the o-rings will wear out that fast because there is no lubrication. A little vaseline will help, but not prevent the premature wear. The advantage of the o-ring retainer is better lateral stability than a locator. It biggest disadvantage is that if it is opposing natural teeth, especial those with porcelain crowns, the o-ball eventually can be worn down. With the lower profile the locators does not have this problem as much.

What kind of a dentist would suggest his patients to change the o-rings themselves.It is totally out of the question for one who considers himself more of a DOCTOR than a dental technician.

I would not recommend that patients buy o-rings from sources other than FDA approved providers (i.e. dental suppliers). Companies like the IMTEC Corporation sell bulk packages of the o-rings but will only sell them directly to dentists (as they should). I routinely show my patients how to change their own o-rings and after a few recall visits without problems I’ll give them a few extra to last until their next recall visit.

Hi All, changing of the o-rings seems to vary from patient to patient. I would also suggest changing to the locators and instead of using vaseine, use a small quantity of KY Jelly or a similar based product. Vaseline is a petroleum byproduct and KY Jelly and such products will give the lubrication,and is water soluable.

My case is worst, I have two lowwer dental implants with two ball attachments, the first set of o-rings lasted 2 weeks, the second, only 2 days. Can you explain why they wear out so quickly? Thanks

my guess would be that the implants are not parallel. This would cause each post to have a different path of insertion which could cause the o rings to tear etc.

I don't know what are locators but i feel Dala bona attachments are definitely better in the sense they do not wear off for yers together plus can be adjusted for their fitting.I recently got a call from a patient whom i treated 4 years back for an upper complete denture(Implant retained)doing fine.

Helen If you want to buy your own o-rings to save dentists from charging you a fortune to just change a o-ring i have done it for years saving hundreds of dollars for a office visit call the o-company just google the name . (coxsaki do you call a painter everytime you paint at home)NO

My husbands dentist left the area, gave no extra o-rings. The only other dentistwho deals with mini-implants in the area charged our insurance for an office visit and 30.00 co-pay to us then for the replacement of the o-ring he charged 125.00, for a grand total out of our pocket of $155.00, for a 5 dollar o-ring. I am going to check out the o-company, there has to be a less expensive way. A dental lab just pulled one out and gave us the exact measurements to get them on our own.

How often should O rings be replaced. I've been told once a year? One dentist quoted $1000. Seems too expensive for me.

I use a size 4 dental implant o-ring and I was able to get about 500 o-rings for about $10.00 on Amazon through Mr. O-Ring, which is also nicely tucked in my buying history, so I can easily find them again. I also later went to Mr. O-Rings site (www.mroring.com) and typed in their search box 004 nitrile o-ring it brings up 26 options, go till you see number N70004 I typed in quantity 500 it said $8.66 (that was on 10/1/2020), The staff at Affordable Dentures charged me $75.00 to put 3 new o-rings in my mouth, that's not very affordable (will never do that again) On vacation in Tennesee when I needed new ones while away from my stash of 500, I was able to get some immediately at Rural King where I got 3 small o-rings size 3/32 x 1/16 part #83291 for about $1.50 or so, in their plumbing department I had just pulled out the old one, and took it in and compared them. I knew to try there because I had purchased them before at my home town Rural King. I am currently trying to find a reasonably priced O-ring inserter because I want to save myself the money, but they are a little hard to handle, someone suggested vaseline or ky-jelly to make insertion easier. I pushed my in with tweezers, and a nut pick, like that you use at Christmas, it can be done, it just takes some work. Where there's a will, there's a way! Never hurts to ask, or Google, cause someone will know! It looks like you were asking this question sometime ago, but if you don't need the information now, someone else might find it handy. I know when I first started trying to find my size o-ring I read other people's comments to see where they were getting their stuff at! I also talked to people in the hardware stores that were knowledgeable about o-rings. Best of Luck to all of you who are on a mission to do it yourself. I know I don't have $75.00 to throw around, when it cost under $2.00 to buy through Rural King, and way cheaper than that when you get 500 for little of no money, I figured worse case scenario, even if I bought all the wrong sizes, and it cost me $75.00 to figured it out, it was going to be the last $75.00 I spent!

The O company has changed its name and will only sell to dentist now. The dentist must have gotten mad that they were selling to the public and not making that money. They are saying that you are risking your health to change these yourself so now there is a hefty fine if they are caught selling to the public.

I have lower dentures and the dentist has trapped me as well. I was ordering from IMTECH and now they merged with 3m and will not sell to the general public anymore. I have been changing my own O rings for 3 years. Fine tip tweezers and some patience works every time. I refuse to pay huge prices for 5 minutes of the dentists time and when the rings themselves costs only $5. However i am in a spot of finding them again. If i can not find them and have to pay hundreds of dollars for a simple thing i will opt to have them removed. I will not be trapped. I paint my own house as well as do many others things that others have chosen as a profession!!!!!

Today I took my elderly sister in to have a o ring replaced and we had the o ring so there was not purchase for it. The dental assistant changed the o ring and the Dr. looked at it and said that it was in. The cost was $75.00 for the most a ten minute procedure. I think we should be able to purchase the o rings and put them in ourselves.

I just had the O rings on my lower over denture replaced for the first time. I have 4 mini implants. The entire process was 30 minutes and included a cleaning, and 1 minute oral exam. Total cost was $1000. Insurance paid $600, but this is ridiculous! I am a senior citizen on fixed and limited income.

In USA You can order replacement kits of O-rings of all types . You must only ask for an offer for a kit of O-rings for your implants from Topcaliforniadentist (14052) I must tell You that the change of old rings is a litle difficult but is not impossible. I am 86 year old , but I used to change them myself
