Bone grafting


Your body is very adaptable. You may know it from a fracture, for example, when the leg is in a cast and has to be rested for a long time: The muscle breaks down. Conversely, a bodybuilder has built up more muscle mass through above-average effort. Just like a muscle, a toothless jaw also tends to lose bone mass as soon as the load is removed. It is no longer needed by the body because there are no roots for the bone to support. Over time, your body reacts. A visual comparison is provided by the images on the right (please activate).

In order to be able to plan your dental implants perfectly, you need sufficient bone mass, because implant requires good hold in the bone to be able to transfer the occurring forces properly. The function of an implant can only be fulfilled in the long term if it is embedded deep enough in the bone. Therefore, bone augmentation is sometimes a necessary therapy that must precede implantation.

Long periods of edentulism have weakened the bone and caused the bone mass to decrease. The amount of bone is no longer sufficient to provide the proper foundation for dental implants. Strengthening of the jaw bone is medically advisable before implant planning is performed.

2. insertion of the bone block

Digital volume tomography enables us to prepare the exact-fitting bone block before the procedure. This makes the insertion itself much shorter for the patient and a very predictable step for the implantologist.

3. FIxation of the bone block

Special screws are used to fix the bone block in the right place. Just as with a fracture that has been treated, the body normally begins to form new bone material of its own. In the course of therapy, both bones join and fuse naturally.

4. the bone is "built up

When the bone has gained mass and the inserted bone fragment has fused with your jaw, the implant can be placed and will find sufficient support through sufficient bone mass as desired.

Where does the new bone come from?

To obtain suitable bone material there are 3 possibilities:

  • Bone from the body either from the jawbone or, in particularly extensive situations, from the iliac crest (hip)
  • Synthetic materials when only a small amount of bone needs to be built up.
  • Biological substitute material, for example highly purified bone material from cattle or pigs. Here, a special membrane is usually inserted to support healing.

What procedures are available for bone augmentation?

  • Sinus lift - bone augmentation in the maxilla
  • Bonespreading - gently spreading the existing bone to stimulate new formation in the gap.
  • Distraction osteogenesis - bone gain through natural growth
