CT/CBCT scans and data export

Instructions for a successful 3D planning

• Instructions for CT/CBCT scansfor planning of maxgraft® bonebuilder

Patient preparation:• detachable, metalliferous prosthesis must be removed(artefacts can lead to an inaccurate planning)

• keep metal-free prosthesis

• adjust patient‘s head in a way that beam is parallel to lower jaw occlusal plane

• create a space between buccal soft tissue and the jaw bone by using cotton rolls

• scan patient with the CT-rack, check if titan tubes are complete (10 mm)

• if no CT-rack is available let the patient bite on something (prosthesis, spatula, plasticcard etc.) to ensure immobile lower jaw

• enter LJ oder UJ right-aligned in the patient data file

• Instructions for CT/CBCT scansfor planning of maxgraft® bonebuilder

Settings:• Gantry=0, otherwise scan is not compatible with planning software

(FreeForm, OneGraft3D, SimPlant etc.)

• layer bigger/equal to feed, never smaller (good value 1/1/1)

• field of view as small as possible, spine is not desired

(upper jaw ca. 9-10 cm, lower jaw ca. 10-15 cm)

The scan-level indicator needs to be adjusted in axial and sagittal level at right angle. This can be checked in the alignment-record (Topo, Scout) or in the first axial level.

Scanning the lower jaw:• scan from below lower jaw (first bone-free layer) until scan-level indicator

Scanning the upper jaw:• scan from scan-level indicator to lower end of Orbita (including maxillary sinus)

Attention:

• if patient has moved a second scan should be done

• vary the patient name (John Doe2) to create a new data set

Data requirements

• always send uncompressed images, the correct data file consists of alignment record

• do not include secondary reconstructions

• if more than one data file is created, please save them with different names

(John Doe LW2, etc.) otherwise a reconstruction is impossible

•

Layer thickness

Output format DICOM (.dcm)

Digital Imaging and Communications in Medicine

The distance between single layers shouldbe 0.3 mm for a reliable planning.

Data requirementsUnlinked single frame data images (DICOM)

For CT data:

Only axial images are compatible with the planningsoftware, sagittal images cannot be read in andprocessed.

If combinations of axial and sagittal images arecreated, the whole data set is incompatible.

DICOM data export

In case you export your data on your own, you can find examples on how to export for a variety of different scanner software in the ‘Help’-‘Downloads’ section on www.botiss-bonebuilder.com.

Please check the successful export by using a free DICOM-Viewer software (e.g. XNView/www.xnview.de) before uploading to avoid any delays in planning caused by defective data.

No DICOM

Attention!

If you do not find the right format, please ask your radiologist for advice

The output format of a digital radiological device can easily be switched within thesettings without taking another scan.
