All-on-four/All-on-six dental implants is a solution to recover teeth for those who have lost all their teeth or lost many teeth without using too many fixtures.
In the past, removable denture was the first choice for those who have lost all their teeth because of 2 main reasons:
However, the removable denture has many defects (such as entanglement in the mouth, break-in time to adapt, chewing function reducing…) that makes many patients afraid to do.
Nowadays, with the development of modern dental implants, the All-on-four / All-on-six dental implants technique were invented to help effectively teeth restoration, bringing many outstanding advantages.
All on four Dental Implants
All on four dental implants is the solution provided by Nobel Biocare (USA), which is recommended by leading implant experts for cases of total teeth loss. In particular, this technique is applied commonly for the lower jaw; if it used for the upper jaw, the jawbone needs to be strong.
All on four dental implants uses 4 implant fixtures on one jaw, including 2 straight implant fixtures in the 2nd tooth position and 2 tilted implant fixtures in the 5th tooth position with a maximum tilt angle of 45°. In addition, the all-on-four dental implants technique is supported by Multi-unit Abutment, restoring 12 teeth per jaw on 4 Implants.
All-on-six Dental Implants
All on six dental implants technique is an improved solution when using up to 6 Implant fixtures to place in the jawbone. With the All on six implants technique, the fixtures are usually erected. The installation position is also distributed more evenly than using all-on-four dental implants.
