Measurement
Turn on measurement, then click two points on the bone, the implant or a screw. Distances are in millimetres, on the manufacturing meshes.
Implant section in blue, bone section in ochre. Models simplified for the web: measurements are indicative; the reference dimensions are those of the design file.
Reading the case
What the model shows
The implant follows the curvature of the contralateral vault and rests on the bone edge all around its perimeter. Eight peripheral tabs each take an osteosynthesis screw: fixation stays outside the defect, on healthy bone.
What to look at in the viewer
- 01Coronal or axial plane through a tab: the screw’s path through the tab and into the bone.
- 02Transparent bone: distribution of the eight screws around the defect.
- 03Implant moved away: shape and limits of the bone defect.
- 04Measurement: diameter of a perforation, distance between two screws.
