Orthogonal views of right zygomatic implant

These orthogonal cross-sectional images demonstrate the appearance of the right zygomatic implant from various perspectives. The superior surface of the implant extends through the floor of the right maxillary sinus, and mild mucosal thickening is noted. The portion of the implant embedded within the right zygoma appears normal.

Orthogonal views of left zygomatic implant

These orthogonal cross-sectional images demonstrate the appearance of the left zygomatic implant from various perspectives. The superior surface of the implant extends through the floor of the left maxillary sinus, but no significant signs of antral inflammation are noted. The portion of the implant embedded within the left zygoma appears normal.

1. Apex of implant 12 extends through nasal floor

The apical half of the implant placed at site 12 extends through the floor of the nasal fossa. The remainder of the implant appears to be embedded in bone.

2. Apex of implant 22 extends through nasal floor

The apical half of the implant placed at site 22 extends through the floor of the nasal fossa. The remainder of the implant appears to be embedded in bone.

3. Exposed buccal threads on implant 33

The coronal third of the buccal threads of the implant at site 33 are not embedded within bone. The remainder of the implant appears osseointegrated.

Normal implant 32

The implant at site 32 appears normal radiographically. No exposed implant threads are radiographically apparent.

4. Exposed buccal threads on implant 31

The coronal third of the buccal threads of the implant at site 31 are not fully embedded in bone. The remainder of the implant appears to be normally osseointegrated.

Normal implant 42

The implant at site 42 appears normal radiographically. No exposed implant threads are radiographically apparent.

5. Exposed buccal threads on implant 43

The coronal third of the buccal threads on implant 43 are not fully embedded in bone. The remainder of the implant appears to be normally osseointegrated.

6. Intracranial calcification of internal carotid arteries

Calcifications are visible lining the walls of the parasellar segments of the right and left internal carotid arteries. These findings may represent signs of arteriosclerosis. The significance of this finding cannot be determined based on CBCT imaging alone.

7. Extracranial calcification of carotid arteries

Calcifications are visible lining the walls of the right and left carotid arteries at the level of C3/C4. This finding may be a sign of atherosclerosis and cardiovascular disease.

8. Mild cervical degenerative joint disease

Small osteophytes and mild subchondral sclerosis are present on the articulating surfaces of the cervical vertebrae. This is suggestive of the presence of mild cervical degenerative joint disease, which is an incidental finding with no clinical significance.

9. Calcified stylohyoid ligaments

The stylohyoid ligaments are partially calcified bilaterally. This is an incidental finding with no clinical significance.

10. Physiologic intracranial calcifications

Midline and parasagittal physiologic calcifications are present intracranially. This is an incidental finding with no significance.
