Different treatment modalities exist to restore the chewing function in case of an (extreme) atrophic maxilla. We describe a technique for reconstructing the jawbone in a manner that in a second stage oral implants can be installed with a high reliability in the long term. At the same time this technique allows immediate fixed function from the start of the treatment to provide immediate comfort in these otherwise utterly unpleasant transient healing period.

Monocortical cranial bone blocks are taken to reconstruct the atrophic maxilla. Immediate provisional implants are installed upon which the next day a temporary fixed bridge is cemented. After six months of healing, regular oral implants are inserted following again an immediate loading protocol with a temporary fixed bridge. After another healing period of 6 months the final bridge is made.

The long term results up to more than 10 years will be discussed. The overall implant survival is 95% without marginal bone loss (MBL) in 65% of these implants. 80% has less than 0.19mm MBL . Furthermore the prosthetic advantages and procedure of this treatment will be discussed.

These results prove that this method is a comfortable and reliable treatment option in case of an (extreme) atrophic maxillae.
