Accuracy of Surgical Guide in Implants

Keywords

Surgical guide, Computer guided implantology, CBCT voxel size

Brief summary

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 .

Detailed description

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 (voxel size 0.4mm & 0.2mm)
