APPENDIX D Stereolithographic Reproduction of Anatomic Structures Using a CT or CBVT Scan
1. Call the scanning facility for appointment, or if you have a cone beam volumetric tomography (CBVT) scanner in your facility, schedule the patient according to the usual procedure.
2. Determine whether the facility has ever used the scanning protocol required for anatomic model generation.
4. Send a scan protocol to the scanning facility. More important, send it to the technologist doing the scan. To prevent any mistakes, send a copy of the scan protocol with the patient.
5. It is important to fill out the patient information sheet and fax it directly to the facility generating the anatomic model, or it can be sent with the electronic computed tomography (CT) data. Because necessary scanner data are included on the patient information sheet, ask the scanning technologist to fill out that portion.
6. To prevent any misunderstanding about the anatomy to be scanned, mark the area to be scanned on the skeletal worksheet and send it with the patient to the scan facility.
7. Whether the data are being sent from the hospital or the implantologist’s office, include the necessary patient information sheet and skeletal worksheet.
8. Send the data overnight delivery; this helps prevent any delays or damage to the electronic data.
9. If you are concerned about the scan facility or with the scan quality, call your model-generating facility, which will call the scan facility immediately before the scan. The scan facility should proceed step by step through the protocol to obtain a quality scan.
2. When scanning the patient, proceed three slices above and three slices below the area of interest.
