Are you a Candidate for the ALLON4
Fewer Implants, Less time and Money combined with a lot of publicity and marketing, the All On 4 has become a very popular and requested treatment option, but is it a good option for you? only In the appropriate circumstances.
The most common reasons I found were –
If there are 6 Implants placed and there is an instance that an implant fails due to infection, non osseointergration then the arch is still in a good position having 5 Implants left. When an implant fails with 4 in place the arch is compromised and you will have a 0-on-3. Basically the specialists like to err on the side of caution for the successful outcome for the patient.
6 is often recommended in the upper maxilla as the bone is less dense than the lower adding more assurance on a long term successful outcome
Patients who have worn dentures for years have substantial bone loss but also lip and cheek support that makes it difficult to achieve a truly esthetic result with the 4 Implants.
The Allon4 Technique requires removing bone
All-on-4 dental implants cannot be placed in the molar areas of the mouth where bite force is greatest.
If one of your angulated implants fails, it will destroy a lot of bone dur
