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 .
