Orthogonal views of embedded wire

These orthogonal cross-sectional images demonstrate the embedded fixation wire from various perspectives. The buccal insertion point of the wire is positioned distobuccally to the cervical third of the distal root of tooth 47. The wire emerges from the crest of the alveolar process approximately 11 mm distally to tooth 47.

Note that the bone surrounding this wire appears completely normal. This wire is not likely the source of the patient's symptoms.

Sagittal views of posterior fourth quadrant

These sagittal cross-sectional images demonstrate the normal appearance of the bone surrounding the embedded wire in the posterior fourth quadrant. However, the right mandibular nerve canal exhibits an unusual shape, and it is likely that the patients symptoms are secondary to an issue related to the unusual morphology of the right mandibular nerve canal.

1. Localized increase in caliber of the right mandibular nerve canal

A localized increase in the caliber of the canal is present distally to site 48. This may represent a traumatic neuroma.

2. Localized decrease in caliber of the right mandibular nerve canal

The caliber of the canal is significantly decreased at site 48. This unusual appearance of the canal is suggestive of a potential history of trauma to the canal.
