sinus elevation
In the upper maxilla there is often a scarcity of bone due to the fact that the maxillary sinuses are very pneumaticised with barely a few millimetres height within which to insert the implants
If a lot of implants are to be inserted it will be necessary to perform a sinus elevation opening up an osseous window on the facial side and filling in part of the sinus with autologous and heterologous osseous materials.
On other occasions, where the bone scarcity is not as pronounced, height can be gained with the transinusal sinus elevation using Summers osteotomes.
At the Clinic, in collaboration with Dr. Nicolás Romano, we have designed specific osteotomes which enable us to double bone height.
In the case we show to follow, the patient lost an upper molar. With this example you will understand the basic principles of this technique.

In the panoramic x-ray you can see that we only have 6mm of bone height in which to insert an implant. |
In the same intervention a sinus elevation was performed using osteotomes. Bone graft was inserted together with an implant of 13mm height by 5mm width. In the image you can see how the bone surrounds the end part of the implant. |

After 5 years you can see how the implant is surrounded by bone (the whiter structure) and the osseointegration is perfect. |
