BUT! Due to modern methods nothing is lost, even in case of defective bone structures. Such circumstances can be found mostly in the upper jawbone. In the jawbone, the region above the teeth, there is the facial cavity. If the teeth get lost, the jaw-backbone begins to decline, and the bone structure grows so thin, that there is not enough room under the facial cavity, even for the shortest implant.

In such cases implantation can happen by lifting the basement of the facial cavity. We use own or artificial materials to replace bones.
