Body<br />

Objectives: The aim of this study w<strong>as</strong> to evaluate the accuracy and compare image information<br />

obtained using cone beam CT (CBCT) and multi-detector CT (MDCT).<br />

Methods: A lower mandible from a human cadaver w<strong>as</strong> examined using CBCT (3DX Accuitomo,<br />

Morita Co, Kyoto, Japan) and MDCT (Asteion 4, Toshiba Co, Tokyo, Japan). The height of the<br />

mandible w<strong>as</strong> me<strong>as</strong>ured in three sections and w<strong>as</strong> calculated <strong>as</strong> the length of the vertical line<br />

from the alveolar crest to the superior border of the mandibular canal in each section. DICOM<br />

viewer CT imaging data were simulated using the Nobel Guide Procera software (Nobel Biocare).<br />

The simulated images were used for evaluation and examination of cortical and cancellous<br />

bones <strong>as</strong> well <strong>as</strong> trabecular structures.<br />

Results: The quality of simulated images w<strong>as</strong> good for both MDCT and CBCT. However, greater<br />

details were obtained from CBCT images. T<strong>here</strong> w<strong>as</strong> no significant difference in the simulations<br />

of the implant surgery software images obtained using MDCT and CBCT.<br />

Conclusion: CBCT w<strong>as</strong> superior during observations, such <strong>as</strong> the observations of trabecular<br />

structures, and had high distance accuracy.<br />
