Abstract
The morphology and quantity of bone are essential for preoperative planning of implant placement in the mandible. The thickness of the cortical bone has a larger influence on the initial stabilization than the length of the implant fixture. Earlier studies reported that the cancellous (CAB) and cortical (COB) thickness is the key to successful implantation. Implant success rate might be affected by the CAB and COB thickness. The quantity of bone is an important factor for long-term maintenance of the stability of the bone-implant interface. In the present study, we quantitatively and precisely evaluated the CAB and COB thicknesses in five sections from 6 mm anterior to 18 mm posterior to the mental foramen. To our knowledge, this is the first computed tomography study to report on quantitative measurement of the CAB and COB thicknesses and morphology of the mandible in a wider area from anterior to posterior of the mental foramen. For implant installation, careful evaluation and full knowledge of the thicknesses of CAB and COB thickness, as well as the shape of a mandible, are necessary, providing anatomic guidelines to clinicians, which will be helpful for implant surgery.
