Failing maxillary implants

The implants at sites 18, 17, 15, 13, 21, 23, 25, and 28 all exhibit negligible osseous coverage and are on the verge of failure. The bone grafting material demonstrates no evidence of osseointegration. The floors of the right and left maxillary sinuses are intact. Removal of these existing implants is indicated to prevent further osseous destruction within the maxillary alveolar process.

Axial views of maxillary implants

These axial cross-sectional images demonstrate the fragmented appearance of the maxillary alveolar process, which is partially due to failed graft osseointegration and also due to bone destruction caused by the existing maxillary implants.

Failing mandibular implants

The mandibular implants at sites 47, 44, 42, 32, 34, and 36 exhibit minimal osseous coverage and are pending failure. The right and left mandibular nerve canals have not been compromised. Removal of these existing implants is recommended to prevent further destruction of the mandibular alveolar process.

Axial views of mandibular implants

These axial cross-sectional images demonstrate the absence of osseous coverage overlying the buccal aspect of the implants at sites 44, 42, 32, and 34. The implants at sites 36 and 47 exhibit minimal osseous coverage.

Coronal views of maxilla and mandible

These coronal cross-sectional images demonstrate the preservation of the maxillary sinus floors and the mandibular nerve canals bilaterally.

Evaluation of maxillary implant sites

Inadequate bone is available at sites 17, 16, 15, 14, 13, 12, 11, 21, 22, 23, 24, 25, 26 and 27.

Axial views of maxillary arch

These axial cross-sectional images demonstrate inadequate bone volume available to accommodate implant placement at sites 17, 16, 15, 14, 13, 12, 11, 21, 22, 23, 24, 25, 26 and 27.

Moderate mucositis in the right maxillary sinus

Moderate mucositis is present within the right maxillary sinus. This level of mucosal thickening occupies approximately 50% of the antral air space and may impede a potential right maxillary sinus lift.

Moderate mucositis in the left maxillary sinus

Moderate mucositis is present within the left maxillary sinus. This level of mucosal thickening occupies approximately 50% of the antral air space and may impede a potential left maxillary sinus lift.

Evaluation of mandibular implant sites

Inadequate bone is available at sites 47, 46, 45, 44, 43, 42, 41/31, 32, 33, 34, 35, 36 and 37.

Axial views of mandibular arch

These axial cross-sectional images demonstrate inadequate bone volume available to accommodate implant placement at sites 47, 46, 45, 44, 43, 42, 41/31, 32, 33, 34, 35, 36 and 37. Note that virtually no bone separates the alveolar crest form the mandibular nerve canal at sites 47, 46, 45, 35, 36, and 37, and implant placement should be avoided in these areas.

1. Sphenoid sinus mucositis

Mild mucositis is present in the right loculation of the sphenoid sinus. This is a non-significant incidental finding.

2. Ethmoid sinus mucositis

The ethmoid air cells are partially opacified. This is suggestive of the presence of ethmoid sinus mucositis.

3. Mild cervical degenerative joint disease

Small osteophytes and a joint mouse are present in the articular regions of the atlas and dens of the cervical vertebrae. This is a common incidental finding with no clinical significance that is suggestive of mild cervical degenerative joint disease.
