For the correct acquisition of the patient’s CBCT, some rules should be followed so that the acquisition result is correct for use in surgical splint design software.
If any of the rules are not observed during the download, it is possible that the 3D volume (CBCT) is not satisfactory and cannot be used to print the splint.
The rules for the correct reception of the cone beam computed tomography, CBCT, do not only apply to its use in the construction of a surgical splint, but also to its correct reading and the transfer of correct information to the attending physician.
Instructions for correct download:
1. A complete tomography of the jaw is required, not a segmental one
2. The patient should remain motionless throughout the radiation. Any movement will cause the image to blur and will not be usable.
3. The use of soft tissue retraction forceps helps to delineate the gingival sulcus.
4. High definition CBCT and DICOM files will facilitate case analysis.
5. The patient should not be in a concussive position to avoid overlap of the teeth.
6. If the patient is edentulous, a base plate should be used.
After each examination the CBCT files should be reviewed immediately and if any of the above is not the case the download should be repeated.
