If you have ever been told you are not a candidate for dental implants or that you would need bone grafting, you may have looked into the All-On-4 dental implants technique. Normally, dental implants that are surgically implanted into the jawbone require that there be enough bone material to support and stabilize the implant root form. However, some patients who have been without teeth for a number of years don’t have enough bone left to support regular implants. In these cases, bone grafting has been a good solution for many. However, it requires more healing time and financial resources than some patients have. Dr. Paulo Maló of Portugal developed the All-On-4 technique to help his patients who were facing these problems.
The Newer All-On-4 Dental Implants
Dr. Maló realized that just four angled dental implants in the front of the jaw could anchor an entire denture arch. The illustration to the left shows the placement and angle of the four dental implants.
There Are Risks Involved
We want to make you aware that there are some risks associated with the technique. It’s important to understand them, so you can come to an informed decision about the type of treatment you decide to go with.
To begin with, the procedure is recommended for patients who already have low bone density. This can be a possible source of risk, because there needs to be sufficient bone structure available to anchor the implants. In addition, the technique involves greater risk of the entire prosthesis failing because, if just one implant fails, there is no way to just repair the faulty part and the entire case has to be re-done.
In addition, the root forms used in the All -On-4 technique are significantly smaller than those used with regular dental implants. The photo to the left shows a traditional root form and this smaller form. Notice that the threads of the regular implant are longer and deeper. The smaller implant can become loose more easily, which would lead to failure of the prosthesis.
In the long run, the best way to decide which kind of implants will work for you is to discuss your situation with a qualified dentist. Dr. Root can help you make that decision. In the meantime, you can learn more, by clicking here to read our Implant Overdentures page.
