Assesment of the Accuracy of Surgical Guide Designed From CBCT With Different Voxel Sizes

Assesment of the Accuracy of Surgical Guide Designed From CBCT With Different Voxel Size in Computer Guided Implantology Randomized Clinical Trial

Accuracy Of CBCT affected by many factors. On of the most factors the affect the image quality is voxel size. Larger voxel size give a higher accuracy of the images but with higher radiation dose.

The study is to assist the accuracy of surgical guides designed from CBCT with different voxel sizes .
