| Popis: | As computerized tomography (CT) becomes more widespread in implant treatment planning, dentists are bound to encounter more uncharacteristic anatomical conditions in the jaws. This retrospective study examined the prevalence of one such anatomic variance on 78 CT scans of human mandibles. Irregular heterogeneous circular radiopacities with internal radiolucencies were present in a majority (97.4%) of the CT scans examined; however, the phenomenon only appeared pronounced in 28.9% of this group. Bone radiodensity was higher in the regions with the phenomenon as compared with adjacent bone without the phenomenon, which suggested no adverse indications for implant placement. |
