A major problem of the dental implant is in many cases the lack of sufficient bone offer, because it is believed that an implant for the physiological initiation of the chewing forces in 
the jawbone at least should have a length of 10 millimeters. 
In the mouth, jaw and facial surgery, different surgical procedures are used by which the bone implant can be improved and made up. In the case of large bone defects previously taken routinely autologous bone from the iliac wing of the patient and then transplanted into the respective jaws

After a healing period of about 4 to 6 months can then be implanted into the bone built up. It is, therefore, two surgical procedures that require both a certain time of healing. 
Overall, it is a waiting period of approximately 8 months needed to fix teeth on the implants can be.
As part of the preimplant building measures, it is now using a new method of stem cell therapy, managed to achieve a better and faster bone regeneration and wound healing. With stem cell therapy, the body's own cells are used and allow bone-replacement material in connection with a compact and faster healing.
In this method the patient a small amount of bone marrow is taken from the pelvic bone (Fig. 2) and in a multi-phase recycling process, the "body's own stem cells and other biological building blocks that the body needs for bone formation, and won.

Subsequently, a bone substitute material in bone defects of the jaw is introduced and enriched with the concentrate of stem cells. It is often possible to insert the implants in the same surgical procedure, so that the Gesamteinheilzeit now be reduced to 4 Months.
Side effects, allergic reactions and infection transmission are excluded, since they are stem cells are the body's own constituents.
Benefits of stem cell therapy:
Minimally invasive
No loss of bone volume mounted
No effect on iliac crest
No foreign blood products
No known allergies
The same healing time (3-4 months) as for large-volume bone grafts
Mainly, this method is suitable for augmentation of the maxillary sinus floor augmentation in the form of the so-called (Fig. 3a).
This material is the replacement of the stem cells over a sinus access between sinus mucosa and maxillary placed Fig. 3b).
