The All on Four Dental Implants technique was designed by Portuguese dentist, Dr. Palo Malo, to eliminate the need for expensive bone grafting. An implant dentist can use this system to place a full arch of teeth for a patient with low bone density.
How it Works
Highly angled implants are placed in the anterior of the jaw. This angled placement attempts to provide more stability to the denture when there isn't enough bone present. This concept is demonstrated in the photo shown to the right.
Problems With This System
Dr. Elrawy will give you the full story so you can make an informed decision about this system.
On the other hand, a well-known national chain of dental implant clinics puts all-on-four in just about everybody they see that's missing teeth. Dr. Elrawy will perform this procedure when it is appropriate, but it is not for everyone. Many feel this technique is a shortcut used by dentists to save money and treatment time.
Bone grafting is the standard of care when placing dental implants. When this step is cut out, there is an increased likelihood of failure. The increased stress placed on the implants makes long-term stability a problem.
Bone atrophy is another concern when using this treatment. When you are missing teeth, your body resorbs the bone and minerals to be used elsewhere. Dental implants prevent bone resorption and stimulate new growth. Since implants are only placed in the anterior portion of the jaw, this leaves other areas at risk for weakening, shrinkage, and fracture.
