3D Facial Surface Scanning

Our facial scanner technology uses an optical scanning technique to capture the shape, texture and appearance of the face.

This information is gathered without the use of X-rays at an extremely high resolution. Differences of less than ½ mm can be detected in three dimensions.

Sophisticated software allows the surfaces of one facial scan to be matched up to the surfaces of another scan taken at a later date, and this means that changes in the face can not only be visualised qualitatively, but can also be measured and quantified.

This is already a powerful tool, but when used in conjunction with cone beam CT scanning, the possibilities become even more extraordinary, in that the surface scan can be matched up with (registered) the cone beam CT scan so as to visualise and quantify the changes in the face as a result of changes in the jaws. Using sophisticated surgical planning software, it is also possible to simulate the changes in the face that may result from planned surgical procedures.

Face scanning in orthodontics will also allow the face to be studied as orthodontic treatment takes place and will make it easier for the orthodontist to observe both positive, and negative alterations in facial profile and appearance.

Scan data is presenting on CD and may be viewed on any Windows 98 or XP computer. A print out is also provided of 8 standard views, all derived from a single 1.5 millisecond scan. The short scan time means that even children and babies may be scanned with ease.

The 3D surface image is captured using a high precision, ultra-fast (1.5 milliseconds) 3D photography device – the 3dMDface System from 3dMD ltd.
