This missing bone can be reconstructed (augmented) with different techniques. Sometimes this procedure can take place parallel to the insertion of implants. In those cases a second surgical procedure is unnecessary.
To rebuild themselves, our bones need more time than the soft tissue does. To build new bone, it is covered, in its growth phases, with a membrane to protected it from being invaded by soft tissue. This growth phase encompassed a few months. A material substituting bone or one's own bone can support the build-up additionally.
In the sides of the upper jaw, it is possible to correct a too-flat jawbone by decreasing the adjacent sinus cavity. By means of this proven method, it is possible to loosen the mucuous membrane from its base and to relocate it to the top. The tent-shaped cavity is then filled with a bone substitute and stabilized. Covered with a membrane, stable bone grows in in a few months.
