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?
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.
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.
