Sinus augmentation combined
with onlay/inlay grafted from chin - 2 |

The procedure is used to restore the alveolar ridge prior to implant treatment in case of a severely resorbed maxillae.
Procedure performed in local anesthesia with proper preoperative sedation. Preoperative antiobiotics and antiinflammatory medication.
This tutorial is the second of two procedure tutorials describing a sinus augmentation combined with onlay/inlay grafted from the chin.

Palatal placed incision. Mucoperiostal flap mobilized by horizontal periostal incision and a light finger pressure.

The access to sinus is obtained through a lateral cortical window by the use of round burr to avoid cutting antral mucosa. The size of the window is determined by the length of the planned augmentation. All bone cutting procedures should preferebly be performed with two suctions to allow bone collecting in a suction device (*) in one of the suction tips. The lateral cortical window is pushed with caution a little toward the sinus to release the antral mucosa at the borderline. The antral mucosa is further mobilized with curved sinus instrument (*).

Finally the cortical window is carefully loosened from the sinus lining and stored temporarily in saline. Alternatively the cortical plate can be pushed all the way inside the sinus together with the antral mucosa.
The antral mucosa is lifted according to the planned augmentation height.
