Sinus lift with bone loss from missing teeth
The maxillary sinus is the largest Nasenebenhöhle and lies on both sides just above the alveolar processes of the maxilla.

After loss of the maxillary teeth of the alveolar bone loss in this region rapidly in height, so that pushes the insertion of endosseous implants in this area for lack of bone problems. The claim that is greater after the loss of teeth, the maxillary sinus is wrong and based on the relative impression on the radiograph.
Anatomical location of the maxillary sinus in relation to the surrounding anatomy
For successful implantation in the maxillary area should have a bone height of at least 10 millimeters available, shorter implants are possible but the chances of success low.
Bone as an anchor
In order to augment the bone in that region again, the technology has established itself the Sinusliftoperation. It was first published in 1980 and presented by Tetsch 1988 in German literature. 
The principle is to be placed on the maxillary sinus floor bone material, so that by the ridge again increases in volume and height. There is a lateral fenestration of the maxillary sinus, the bone of the window is retracted into the sinus cavity and wrapped it carefully dissected the sinus mucosa (Schneiderian membrane) into the maxillary sinus. Among the now created cavity can substitute whatever origin always be placed.

Situs after insertion of the augmentation
After appropriate Ausheilungszeit then implants can be placed.


Principle of the sinus floor augmentation (side view)
DVT control screen in the maxillary sinus floor augmentation of a successful on both sides with 3 implants:

Internal and open sinus lift
Various modifications have now emerged. Thus there are internal sinus lift and the open sinus lift. The open sinus lift corresponds to the previously described scheme. The internal sinus lift is that it is raised above the pre-drilled bone canal for the implant to the remaining bone and thus the maxillary sinus mucosa using various Osteotome. In this way, the augmentation is introduced. Each method has its indications and are dependent on the particular anatomy.
Principle must always be taken that at the time of Sinusliftoperation the sinus infection has not. If in such an operation in a maxillary sinusitis hineinoperiert "" it can lead to serious complications.
Artificial bone material or own?
At moderate augmentation alone can be used with artificial bone substitute. If the loss is greater, so it makes sense to augment with a mixture of autologous bone and bone substitute. For best results, however, with the stem cell therapy (see stem cell therapy to reach), is being greatly accelerated by the body's own stem cells in bone growth augmentation. In addition to the shortened healing time of implants in bone built up the quality of bone after the recent scientific findings of over 20% has improved. The healing time of bone structures Stammzellenunterstützten is 3-4 months.
The healing time for the other methods are of course quite different and can take up to one year. However one should give preference to the timely healing.
