Body<br />

Objective: Several imaging techniques are currently <strong>available</strong> for the presurgical and postsurgical<br />

examinations <strong>including</strong> intraoral films (i.e., periapical and occlusal radiographs), panoramic<br />

radiographs, cephalometric radiographs, plain (conventional) tomography and CBCT. The<br />

purpose of this study w<strong>as</strong> to compare the accuracy of these different modalities in implant<br />

placement.<br />

Materials and methods: Articles in PubMed from 2000 to 2010 were reviewed.<br />

Conclusion: A combination of techniques is usually used to obtain the required diagnostic<br />

information for implant placement.<br />

Virtual implant planning using CBCT data allows the clinicians to predict and be prepared<br />

for complications within and after implant placement. The 3-D image volume that can be<br />

reformatted using software enables the technicians to visualize the relative structures, e<strong>as</strong>ily.<br />

Considering that minimal radiation dose in 3D imaging modalities (1/8th the radiation dose<br />

in CT), higher geometric accuracy and lower cost, Cone-beam CT is an advantageous system for<br />

implant treatment planning.<br />
