I had 3 - 4.0 4mm intregal direct screw-in post/ abutments with flat connecting surfaces placed on a lifecore sustain internal bevel implant . This was for a 3 part bridge . It fell off after one month . From what I gather, abutment and implant should mate perfectly . Dr. just wants to re glue bridge back on . Any advice would be appreciated . Thank You Robert.

Hi Robert M,

When you say a 3 part bridge do you mean a 3 unit bridge? If so, why were all 3 implants bridged together and not done as separate crowns?

Ideally the parts should mate "perfectly". But in a lot of cases it doesn't work out that way. First of all it is not ideal to mix parts from one implant system with another. However it can be done and sometimes has to be done in certain circumstances where someone comes in with an old implant and needs a new crown and the parts are no longer available. Something that occurs quite frequently (but is rarely if ever mentioned to the patient) is the angulation of the dental implant. It may be a bit skewed meaning the implant itself may be crooked or too close to an adjacent tooth or other implant which makes getting the prosthetic pieces and crown portion a bit difficult to fit properly. This situation can be caused by carelessness on the surgeons part or sometimes it cannot be avoided due to the patient's anatomical structure as the implant needs to be anchored in healthy, adequate bone.

By any chance did the dentist cement this on with temporary cement? That too is commonly done and then after a few weeks the crowns or bridge is removed and cemented on with permanent cement.

Hi Brianna , Thank you for your reply. The reason for a 3 unit bridge is teeth 18,19,20 Take a lot of stress. As far as I can figure , the abutment only rests on implant and the screw is the only thing that keeps it from sideways. The abutment and the implant don't match. I think this is why it is loosing.

Robert,

Any chance you could have the dental office email you a post op xray of the bridge and post it here???

Unless you have a compromised dentition meaning you are missing other teeth and that has affected your bite or you have periodontal disease or some other issue to warrant a three unit bridge.... it is not always ideal to bridge all three implants together as cleaning them can be a bit tedious. So I'm wondering why the dentist chose to do it this way.

The abutment is suppose to be screwed into the implant or perhaps in some systems cemented into the implant. The crown portion is cemented over the abutment. Nothing is suppose to be just resting on the implant. Yes, the proper size screws need to be used and they usually have to be torqued a certain amount for stability. Do you know if he did any of those things??

Here is a cute little animation and explanation of an impalnt...

Hi Brianna , I dont have a post op. but I can tell you that My sustain internal bevel implants are perfect and mouth has no abnormalities. Everything is perfect. I picked this up on the internet. They said that if the abutment doesn't fit properly it can have lateral movement. Which can cause loosening and you wont have microbial seal. This can cause many problems , is this true. Robert

[Bryanna]

Robert,

Yes, that statement is very true.

I have to tell you that it is standard protocol to take an xray after the abutments are placed to be sure that they are seated down all the way. It is also recommended to take another xray after the crowns or bridge are put in to evaluate how that seats interproximally so that the patient can be instructed on how to properly floss around them. It is more difficult to floss underneath a bridge and it would be good for you to know how to do that properly.

Robert, may I ask why were these teeth removed? Had they been root canaled?

These teeth were beyond repair . One tooth was ruined by root canal perforating into the furcation area. as far as seating goes , a flat surface doesnt seat well on a beveled implant from what I have read. Robert

[Bryanna]

Robert,

Again, you are correct. The parts have to be compatible.
So what are you going to do?

Brianna, Will get proper abutments put in and be out $3,200.00. Thanks for your time you took to educate me ,much appreciated R0bert

Robert,

I've been in the dental field for 35 yrs.... I'll let you in on a little secret....
Dentists are accustomed to compromising on their fees or reimbursing them to patients who have had their dental work fail within a short period of time. Whether or not you stick with the same dentist or go elsewhere, the same principal holds true.

Never hesitate to state your discontent and that you want a reimbursement.

I wish you well!!
