The ScanAnalogs unite the function of a laboratory analogue with the one of a scanmarker
The new ScanAnalogs by Zirkonzahn replicate in their role as laboratory analogue the exact position and orientation of the implant.
However, the ScanAnalogs dispose of a special geometry, integrated in the software which also makes it possible to scan them. Contrary to a traditional scanmarker the scanning process is made on the negative impression of the full-arch (img. 1). The detected position can be directly transferred to the software so that the fabrication of a plaster model is no longer required. The ScanAnalogs are being screwed on traditional transfers and fringed in the impression (img. 2).
The ScanAnalogs are made of anodized white metal and dispose therefore of a non-reflecting surface. This makes the use of a scan spray unnecessary. That way possible inaccuracies caused by irregularly distributed scan spray, can be avoided.
The ScanAnalogues have the following functions:
- Scanmarker (digital reference of the position)
- Laboratory analogues (physical simulation of the implant)
The ScanAnalogs are the result of the development of the original idea, which included the use of traditional laboratory analogues on the model. In this case the special analogues would have executed the function of a digital transfer. Thanks to the optimization of their geometry the multitude of its usages has increased:
Its special form makes it possible to scan them and enables the detection of the position of the implant.
Using the detected data physical models can be produced with the help of milling machines, 3D print, stereo-lithography or other similar technologies.
The material, out of which the ScanAnalogs are made, can vary depending on the technology which has been used for the scanning process.
FABRICATION OF DIGITAL IMPLANT MODELS DIRECTLY OUT OF THE IMPRESSION
In this case the special analogues serve as digital markers.
The following sequence shows the process of the production of digital models after the scan with the help of the ScanAnalogs as scanmarker on one hand and as a real physic laboratory analogue.
Matching between scans and implant libraries
The ScanAnalogs can be screwed within the model or glued with the appropriate adhesive (depending on the material of the model and the analogue).
