Trabecular bone volume and bone mineral density in the mandible.
OBJECTIVE
To explore the possible correlation between trabecular bone volume and bone mineral density in the mandible.


METHODS
Bone mineral density of the trabecular bone was obtained by quantitative computed tomography of 22 edentulous anterior and posterior sections of nine mandibles obtained at autopsy. A computer-based image analysis system was used for morphometric measurements to derive trabecular bone volume from contact radiographs.


RESULTS
A significant correlation was found between trabecular bone volume and bone mineral density. The trabecular bone volume varied significantly between and within mandibles.


CONCLUSIONS
The high correlation between trabecular bone volume and bone mineral density means that the use of quantitative computed tomography prior to implant treatment is a valid procedure.
