AUTHORS Fig. 8: Simple evaporating of the CAD/CAM abutment is common practice, however, this does not comply with the hygiene requirements for a semi-critical medical device. A clean result according to the RKI guidelines is not obtained. performed. Evaporating is not sufficient, and could, in fact, be counterproductive (Fig. 8) . This requires rethinking and readjusting the dental work processes. The third part of the article (logo 40) will present a validated 3-step cleaning protocol which leads to a clean and perfectly hygienic abutment surface [2]. Abutments are medical devices We should be aware that implant abutments are medical devices which have to meet certain criteria. Dental technicians in particular, are faced with a new range of tasks which they should take on responsibly. It should be determined in advance between the team partners dentist and dental technician, who is responsible for which step, and how documentation is to be performed. Conclusion After the first article covered manufacturing and the second article the surface quality of implant abutments, the third part will discuss the following questions: which tasks are assigned to the dental technician in the finishing of pre-assembled or customized implant abutments? Which formula ("cooking recipe") leads to the desired goal? Which steps does a clean abutment surface according to RKI guidelines bring with it? These are all new work steps for dental technicians which need to be incorporated into a state-of-the-art laboratory concept. This information is summarized by the authors on a video which can be viewed on the Sirius Ceramics YouTube channel. The intention, status quo and the validated procedure are presented in an interesting and understandable manner. Scan QR code and view video
