Clinical explanation
- In digital implant treatments, in order to determine the position of the implant inside the software, a piece called a scanbody (Scanbody) is used. The scanbody is fastened onto the implant and is then scanned with an intraoral scanner.
- By seeing the shape of the scanbody in the scan file, the design software understands exactly what position and angle the implant is in. This is done with the help of something called a Library. The library is, in fact, the digital file of each company's parts that helps the software recognize their exact shape.
- After the implant position is determined, the laboratory designs the crown so that it sits and is cemented on the prosthetic parts of the relevant system, such as the Ti-Base. The important point here is that in a digital system, the scanbody, the software library, and the Ti-Base must all be coordinated with each other.
- For example, in one case the implant was the Neodent brand and the crown was to be made on an original Neodent Ti-Base, but the intraoral scan had been done with an Arum scanbody.
- When the laboratory reviewed the scan file, it explained that if the design in the software is done based on the Arum scanbody library, the software usually designs the crown for the Ti-Base of the same system (Arum). Therefore, if we want to use the original Neodent Ti-Base, the exact library of that Ti-Base must exist in the software so that the design is done based on exactly that part.
- If this library is not in the software and the design is done based on another part, we may realize at the time of delivery that the crown does not fit exactly on the Ti-Base or needs adjustment.
- Of course, in some software, such as exocad, it is possible to add different libraries, and in that case one can use the scanbody of one company and the Ti-Base of another company. But this must be done carefully and the laboratory must have the correct library for the part.
- For this reason, in many cases the simplest and lowest-risk approach is for the scanbody and Ti-Base to be from one system, or to be parts whose library exists exactly in the software. This coordination helps the digital design be done more precisely and, ultimately, the crown fits without problems on the Ti-Base and the implant.
