Recently, implant has become an important field in
dental clinic. Radiologic examination is essential for
successful implant surgery. To make an pre-surgical
planning, we can use radiologic examination such as
periapical radiograph, panoramic radiograph,
conventional tomography, CT(computed tomography)
scan images. Panoramic radiograph is widely used by
many dentists for preoperative evaluation in dental
implantation surgery. however, it has some
disadvantages, such as variable magnification from
10%-30%, image distortion and invisibility in the
facio-lingual demension.10 Facio-lingual aspect
evaluation can not be accepted to all of radiographs
except CT scan and tomography.
