Should My Husband Get All-On-Four Dental Implants?

My husband needs to replace his bottom teeth. His upper teeth have been gone for a while and he has dentures there. We were told that you shouldn’t do dentures on bottom teeth because they won’t stay in the way the top ones do. Our dentist said he needs to get all-on-4 dental implants. I just want to explore if there are other options before we make a decision?

Dear Pricilla,

All-on-4 Dental Implants

I am curious why that is the only option he gave your husband. A dentist is ethically obligated to give his or her patients all of their options. He is correct that dentures are a bad idea on bottom teeth. While it is true that dentures will struggle to stay in on the lower arch, that does not happen right away. This is an issue because of bone resorption.

When his teeth are removed, his body recognizes that and begins to resorb the minerals in his jawbone in an effort to be as efficient as possible with his body’s resources. The big problem with that is after ten or so years, he will no longer have enough jawbone left to retain his dentures. This is known as facial collapse.

This bone structure is important no matter what tooth replacement option he chooses.

All-on-4 Dental implants (pictured above) are what dentists will sometimes offer to patients who have lost some jawbone structure but still want dental implants. However, there are other options.

Implant-supported denture

The first thing to find out is whether or not he has lost bone structure. If he hasn’t, then his best option is to get an implant overdenture. This uses between for and six dental implants and then anchors a denture to them.

If he is missing bone, depending on the amount, he has two choices. First, he can have the all-on-4 procedure his dentist suggested, as long as he hasn’t lost too much bone. The one downside to this procedure, however, is that if one implant fails, the entire unit has to be redone. A second option, no matter how much bone he’s lost, is to have a bone grafting procedure done to build it back up. Then, he can do implant overdentures if he wants. He could get a denture too, but bear in mind he will end up with facial collapse. Having dental implants in the jaw bone, prevents that from happening.

Dental Implants Keep Falling Out

I have dentures and have for the last year. I thought I would adapt to them but really hated them. I finally decided nothing was going to change so I opted to get implant-supported dentures. I had six implants placed. In less than a week two of them have fallen out and I can tell a third one is loose. Here are my questions. Should I have to pay for the ones that came out? Do you think more of them will come out? Is there any way this can be fixed?

Dear Clarence,

Implant Overdentures
Implant Overdentures

I will say right off the bat that you made a good choice in what procedure you chose to replace your removable dentures. Dental implants are the closest thing to having healthy, natural teeth in your mouth again.

Your big problem here is your dentist. He doesn’t seem to have any idea what he is doing. With dentists who know what they are doing, there is a 95% success rate. Your dentist has about a 50% success rate and that is just in the first week. Plus, I do not have high hopes for the remainder of your implants. I would not expect them to last.

To answer your questions, no, you should not have to pay for the dental implants that fell out. As I mentioned earlier, I don’t think you should hold out much hope on the others. What I would like you to do is see a dentist with more expertise. I’d like him or her to examine your dental implants and tell you the cause of the dental implant failure.

Reasons for Dental Implant Failure

There are quite a few reasons why dental implants can fail. Here are just a few:

  • One of the major causes of dental implant failure is infection. Often this is the result of poorly fitting dentures.
  • Some dentists try to increase their profits by purchasing sub standard implants from overseas.
  • Inadequate bone support. This is completely preventable if your dentist does the correct diagnostic procedures. If you know ahead of time (as you should from the diagnostics) that you do not have enough bone support, there is a simple solution of having a bone grafting procedure done.
  • Incorrect placement of the implant. It is important that your dentist does 3-dimensional diagnostics, such as a CT scan so that the dental implant is placed correctly. Without that, there can be poor placement that results in serious damage such as damaging a nerve or perforating your sinus cavity.
  • Premature loading—It is important that you wait for your implants to integrate wtih your jawbone. If you don’t and put weight on it with the dental crown before integration, it will cause your implants to fail.

Once you know the cause of the dental implant failure, then you can formulate a plan to get the implants you need for your implant overdentures. I think you will be better off getting a full refund from your dentist and then following the treatment plan of a dentist with a lot more experience who can do this properly.

Then, you will have a stable smile that you will be proud to share.
