Purpose: To clarify basic clinico-anatomic factors associated with cranio-maxillofacial rehabilitation using implants. Materials and Methods: Morphometrically evaluated were items such as the length and width of bone and the thickness of cortical bone at important sites for implant placement into cranial and maxillofacial bones in 30 cadavers at autopsy. Results: At sites corresponding to potential placement sites for implants as the fixation source for ocular epitheses, the mean length of bone was 7.8 mm, and the mean width was 8.3 mm. Conclusion: Useful data have been obtained for the selection of the placements sites, direction, length, and external diameter of cranio- and maxillofacial implants.
