Zygomatic Dental Implants Bone Thickness/Thinness Comparison

Zygomatic dental implants are used in cases of more extreme bone loss in the upper jaw.  They rely on anchorage into the base of your cheek bones which are called  “ zygomatic bone.”  They are commonly done for full arch replacement with a Prettau, zirconia dental implant bridge.

Generally speaking this bone is dense and moderately thick.

The 3D CBCT x-ray image posted shows a comparison of two different patients with different amounts of bone.  The diagnosis of this is critical.

The one on the left has very thin zygomatic cheek bone area for anchorage while the patient on the right has a very thick zygomatic cheek bone.  Obviously having more is always better.  Most people have somewhere in between these 2 images.  The image on the left is likely not sufficient enough to place zygomatic implant and “may”  be better off with sinus lift bone grafts.

This is an excellent article on comparing sinus lift bone grafting versus zygomatic dental implants.  Both have their merits in both are very successful procedures in my hands.

Zygomatic bone -thick versus thin analysis

Often times patients with very thin upper jaw bones also need nasal lifting which is too in the bone graft on the inside of the nose through the mouth.  I will make a post about that soon.

Thank you for taking a look.
