“All On Four” Implants And Fixed Bridges


While this may sound a little complicated, “all on four” prosthetic treatment options are a strong favorite as they are cost-effective, comfortable, simple and convenient for patients. Continue reading for more information about “all on four” implants and fixed bridges so that you can make a more informed decision about your dental treatment.


What Is “All On Four”?

“All on four” is a treatment method trademarked by Nobel Biocare. This method was developed with the intention of eliminating the need for placing several implants into the bone when the patient is in need of a full-mouth restoration. Instead, “all on four” makes it possible for a full-mouth restoration to be done with the use of just four implants, in most cases. In some cases, when the density or amount of bone present in the mouth is less than desirable, the patient may need five or six implants, but this is still much more desirable than the traditional method of full-mouth implant restoration, in which upwards of ten implants must be placed into the patient’s bone. During “all on four”, the implants are also inserted into the bone at a 30-45 degree angle, which has proven to be quite successful in making use of the natural bone structure. Because of this small but effective change, patients with little bone density are considered as candidates for implant placement, whereas with traditional placement methods, they would not.


After the implants are placed into the bone, the patient receives a dental prosthetic that is placed directly on top of the implants. This prosthetic is permanently fixed in the mouth, which will mimic natural teeth as closely as possible.

Fixed Bridges

Bridges are essentially a three-or-more unit cap that is placed over existing teeth in order to fill a small space in the mouth. In some cases, the patient may opt to have the bridge be fixed in place with implants. The implant placement method is the same as that with the full-mouth restoration. After the implants are placed, the bridge will be permanently fastened over the implants. The bridge will be almost impossible to detect with the naked eye, and will function as natural, working teeth.
