Sinus Lifting

Expansion of the sinus

With the loss of teeth, especially the loss of the posterior group of teeth, there is an expansion of the sinus.

In cases where the sinus is enlarged and the bone is thinned and reduced, it is a method to avoid the sinus, to place the implant towards the front or to avoid the back. In a region where it is not possible to do all these, in cases where the bone is very thin, it is necessary to perform a procedure in the sinus before implant surgery or in addition to implant surgery.

Radiographic Examination

The inner wall of the sinus and the outer wall of the sinus are imaged with three-dimensional tomographs to evaluate the thinness of the bone and also to evaluate the sinus structure. In this imaging, it is also possible to examine bone density. As a result of the grading of bone density, the enlarged structure of the sinus is filled to make room for the implant by using the areas where the thinned bone is the hardest, this process is called ‘Sinus lifting’.

How is Sinus Lifting Procedure Performed?

After the physician decides on the implant size and prosthesis to be inserted, he also determines the amount of the procedure to be performed in the sinus. For this, the enlarged sinus area is filled for the implant by using artificial or the person’s own bone.  This procedure is performed under local anaesthesia. Local anaesthesia is sufficient for this procedure. Bone powders, blood tissue obtained from the person himself/herself are placed through the sinus window opened by the physician.

Implants are also placed during the procedure or the placement of the implant can be postponed until later. After waiting for approximately six months, implant overlays can be applied.

The physician can measure whether the implant holds or not with special devices. This measurement makes it safer to place teeth on the implant.
