All on 4 is an implantology registered technique. It is a technique to replace all the missing teeth of a maxilla, and fewer implants are used than in the traditional method. All on 4 methods have the following characteristics:
The all on 4 only need 4 implants per maxilla.
While traditional full mouth implants may require 8 to 10 implants per maxilla, the All on 4 technique uses only 4. Sometimes 5 or 6 are needed in the upper jaw due to its low bone density.
The all on 4 are angled rear implants for optimal strength.
Instead of being inserted vertically, some of the All on 4 implants are placed at angles between 30-45 °. This means that even those patients who have suffered a bone loss may be suitable for the All on 4. This way, they will save a lot of money and time compared to traditional implants, and perhaps even the process of a bone graft.
