What to send:
– Prescription form;
– CT/CBCT scan data in DICOM format;
– Model, impression or optical scan of the surface in .stl or .obj format.
CT/CBCT scan data requirements:
– Dentate Patient (3 or more teeth)
– CT/CBCT examination should be taken using a bite fork/block (not in occlusion).
– All removable prosthetics should be removed.
If the patient has a large distal defect(s), fixed objects which cause streak artifacts (f.e. radiopaque dental restorations or orthodontic brackets) or not radio-opaque fixed prosthetic(s), the CBCT examination should be taken wearing a radiolucent impression tray filled with impression material (A – or C – silicon).
The pictures should be clearly visualized, including both rows of teeth, corresponding bone structures and areas of interest.
Before sending the impressions to the laboratory perform its assessment.
– clear display of all the teeth, gingival grooves, alveolar bone and surrounding soft tissues up to transitory fold;
– absence of pores in the impression;
– good adhesion of the impression material to the tray;
– the inner surface of the impression should not contain thinned or bowed areas;
– the impression should be free of saliva and should not contain traces of blood.
The impression should be decontaminated through disinfection immediately after removal from the patient`s mouth.
Stone model (with no defects or voids)
.stl file generated from an intraoral scan (with no tears or overlapping layers);
If you do not have access to an intraoral scanner a dental lab may be able to create a .stl file from your traditional impression or stone model using a benchtop scanner.
Surgical (drilling) protocol:
Pilot-, Full- and various intermediate protocols are possible.
