Surgical Guide Resources

Product-Specific Records

•CBCT scans (in raw DICOM format). Note: the patient's teeth must be separated during the CBCT scanning process; a commonly used technique involves separation of teeth with cotton rolls.
•Intraoral scans or surface scans (STL format)

•Dual scan records (see Dual Scan Protocol)
•Or CBCT with cotton rolls in between the lips and tongue to show soft tissue contrast in the scan, along with an IOS scan of the patient's ridge
•Bite verification

•The patient's CBCT scan is the only record we ask for. Note: this type of surgical guide will deliver amazing results if we have a good quality scan! Our technicians will perform a quality check and notify your office staff if there is a problem. One of the most common scan defects is a double image, caused by the patient's movement during the scanning process.
•Bite verification

•Series of the patient's full face photographs: comfortable smile looking straight at the camera; exaggerated smile; profile (ask patients to slightly lift their chin so the Ala-Tragus line is parallel to the floor); 2 side photographs (left and right) of the patient's teeth in maximum intercuspation position
•CBCT scan (if the patient is edentulous, follow the dual scan protocol)
•Intraoral scans or surface scans (STL format)
•Bite verification

1Make sure the patient's dentures are not reinforced by any metal substructure.
2Check if the existing denture is fitting well. If there is a space between the intaglio surface and soft tissue, perform a hard reline or use radiopaque impression material to simulate a relined intaglio surface.
3Place radiopaque markers on the denture flange, approximately 5mm from the gingival margin represented in pink acrylic (4 to 6 markers is usually enough).
4Position the denture on a foam block or any radiolucent platform in the CBCT system (teeth should always be oriented upward).
5Confirm the entire surface of the denture was captured in the scan.
6Prior to scanning the patient, make sure the radiopaque marker positions remain the same.
7Perform a second scan of the patient wearing the denture in full occlusion. Note: if denture teeth are separated during the second scan, we cannot guarantee precision of the guided drill trajectory.
