Decision-Tree to Choose the Appropriate V2R Scanning Protocol

Warning Please make sure to use the V2R Scanning Protocol that is suited for your case.





1. V2R™ Single Scan Protocol for Teeth-supported Surgical Guide

Warning: If the patient has metal crowns and/or amalgam, you should preferably use the V2R™ Dual Scan Protocol for Teeth-supported Surgical Guide (#2) because of possible artifacts that could be created by existing restorations.

1A Full Arch Impressions

1A.1 Make an accurate impression of the arch to be treated.

1A.2 Make an impression of the opposing arch and take a bite registration.

Note:

These impressions will later be scanned and transformed into detailed 3D computer images that will be the basis for the surgical guide design. It is therefore important to provide accurate impressions.

1B CT-Scan of the Patient

Preparation of the Patient

1B.1 Patient must remove all metal prosthesis, as well as metal jewellery that might interfere with the region to be scanned.

1B.2 Patient should be in a static position, with the head upright.

1B.3 Patient’s bite should be secure with cotton pads in order to avoid possible artifacts from the opposite arch.

Upper and lower teeth should not touch each other during the scan acquisition.

Recommended space = 5mm

1B.4 Patient must not move or swallow during the scan acquisition.

DO NOT

SWALLOW

DO NOT

MOVE

Scanning Instructions 1B.5 The occlusal plane should be parallel to the plane of image slice generated, with no tilt.

1B.6 The height must be set in order to center the occlusal plane in the field of view (FOV).

1B.7 In case that both arches need to be treated, please provide a separate scan for each arch.

Use the following scanning parameters to perform the CT-Scan :

Parameters Values Gantry Tilt None (0°)

Slice Thickness min 0.2mm / max 0.4 mm Reconstructed Slice Increment Same as Slice Thickness

Reconstruction algorithm Bone Compression None

Format DICOM 3

Requirements • Remaining teeth should be clearly visible (no artifacts). • Upper and lower teeth should not touch each other.

Preparation of the Patient 2B.1 Patient must remove all metal prosthesis, as well as metal jewellery that might interfere with the region to be scanned.

2B.2 Patient should be in a static position, with the head upright.

2B.3 The radiographic guide must be placed firmly in the patient's oral cavity.

2B.4 Patient should bite on cotton pad, in order to avoid possible artifacts occurring from the opposite arch.

2B.5 Patient must not move or swallow during the scan acquisition.

Scanning Instructions 2B.6 The occlusal plane shall be parallel to the plane of image slice generated, with no tilt.

2B.7 The height must be set in order to center the occlusal plane in the field of view (FOV).

2B.8 In case that both arches need to be treated, please provide a separate scan for each arch.



Slice Thickness 0.4 mm (maximum) Reconstructed Slice Increment Same as slice thickness


Format DICOM 3

Requirements • At least 6 radio-opaque markers must be distinguishable on

the CT-scan images. Please ensure that markers are not "lost" in possible artifacts created by existing restorations.

2C. CT-scan of the Radiographic Guide with the Master Model

Scanning Instructions 2C.1 The radiographic guide must be installed precisely onto the master model.

2C.2 The resulting assembly must be placed in the scanner in a position similar to its position during the patient scan.

2C.3 The resulting assembly must be supported by a highly translucent material (such as polyethylene or polyurethane foams).

Use the following scanning parameters to perform the CT-Scan:


Slice Thickness min. 0.2mm / max. 0.4mm Reconstructed Slice Increment Same as slice thickness


Format DICOM 3

Note:

If both arches are to be treated, please proceed to scan one assembly at a time.

3. V2R™ Dual Scan Protocol for Gum-supported Surgical Guide

3A. Full Arch Impression


Note: This impression will later be used to pour a master model in order to validate the fit of the surgical guide. It is therefore important to provide accurate impressions.

3B. Denture with Markers

3B.1 Examine the denture of your patient to decide if you can use it to perform the Dual Scan protocol.

The ideal denture should have: • Teeth of proper size, shape and length • Well established occlusion • Buccal flanges wide enough for gutta-percha markers and

retentive pins positioning • Hard reline only • Secure and close fit to soft tissue and patient cast • No radio-opaque (like Triad® from Dentsply) or metal

materials

Warning: If the actual denture does not meet the ideal denture criteria that are mentioned above, please make a new one before doing the scan acquisition. The V2R™ Gum-supported Surgical Guide is designed from the shape of the denture. It is therefore essential to work from a denture of good quality in order to get a safe and accurate surgical guide in return.

3B.2 Insert 6 or more radio-opaque markers on the outer surface of the denture: • Use the #3 round bur to create at least 6 small holes on the

flanges of the outer surface of the denture - some close to the tooth-gingiva border, others close to the outer border.

• Drill spherical holes of 1mm deep and 1-1.5mm diameter. Avoid making the holes larger than indicated (larger volume of radio-opaque material might cause artifacts).

• Fill holes with a radio-opaque material (preferred material is gutta-percha).

• Plan marker positions evenly on lingual/palatal and buccal/labial regions. Preferred positions of the markers on the denture (case of six markers):

• Ensure markers are randomly distributed in several planes.

Avoid placing markers on the inner surface of the denture.





Note: Radio-opaque markers are used to facilitate the merge of the scanned denture to the CT-Scan of the patient wearing the denture.

3C. CT-scan of the Patient Wearing the Denture

Preparation of the Patient 3C.1 Patient must remove all metal prosthesis, as well as metal jewellery that might interfere with the region to be scanned.

3C.2 Patient should be in a static position, with the head upright.

3C.3 Patient must wear the gutta-percha filled denture.

3C.4 Patient should bite firmly in centric occlusion.

3C.5 Patient must not move or swallow during the scan acquisition.

Warning: If the patient is scanned without your presence, practice the correct seated position of the denture with the patient.

Scanning Instructions 3C.6 The occlusal plane should be parallel to the plane of image slice generated, with no tilt.

3C.7 The height must be set in order to center the occlusal plane in the field of view (FOV).

3C.8 In case that both arches need to be treated, please provide a separate scan for each arch.

V2R™ File Transfer Instructions

1. Before sending any scan data, please make sure that the case prescription was previously sent to V2R Biomedical (by fax: 1.855.432.2850 or email: [email protected]).

2. Create a .ZIP archive with each main folder containing the DICOM file series. For a double scan, there should be 2 separate main folders, so you should create a .ZIP archive for each.

3. Identify the .ZIP files by renaming them:

“LAST_FIRST_Patient.zip” for the patient scan and “LAST_FIRST_Prosthesis.zip” for the prosthesis only scan (if applicable).

4. Go to www.wetransfer.com

5. Add the first .ZIP archive by clicking the “+” sign in the first box and locating it on your computer.

How to compress and uncompress files (zip files) on Windows

A. Locate the file or folder that you want to compress.

B. Right-click the file or folder, point to Send To, and then click Compressed (zipped) Folder.

A new compressed folder is created. To rename it, right-click the folder, click Rename, and then type the new name.
