Dental implants are titanium root forms that are surgically placed into the jawbone. They replace tooth roots and help stabilize the jawbone, preventing bone loss. When bone loss has already progressed, bone grafting can rebuild the bone enough to support implants. But for some patients, this procedure is out of reach. Dr. Palo Malo, a dentist from Portugal, created the All on 4 dental implants technique to help his patients who were faced with this situation.
What are All On 4 Dental Implants?
The All On 4 dental implants technique uses just four smaller dental implants to anchor a set of dentures. The four implants are placed in highly angled positions in the front of the mouth. While the technique can work well for people who might not otherwise be candidates for implant-supported dentures, but it has associated risks you should be aware of.
All on 4 Dental Implants Risks
The risk of failure for All on 4 dental implants is greater than for regular implants. The photo to the left shows the difference between a regular dental implant and the kind used in the All on 4 process. As you can see, the regular implant has longer and deeper threads which make it more stable.
And although the All on 4 procedure is quicker and less expensive, if one of these smaller implants fails, the entire treatment will fail because there is no way to repair a part. In addition, the fact that it is recommended for people with less than normal bone density, there is a greater risk from the beginning that there will not be enough bone structure to adequately support the implant.
