Speed, reliability and effectiveness seemed to be most of the desired goals in recent years, very easily attainable through digital tools and machines. "Slow dentistry", a new trend, which arose in Switzerland in 2018, calls for longer appointments and more time for dentist, patient and assistant. 
CEREC is a synonym for digital dentistry and is now used worldwide. With Dentsply Sirona’s new milling unit “CEREC Primemill” the so called superfast milling mode entered the stage. 2 years ago Kuraray Noritake offered a very translucent new Zirconia to the CEREC users: Katana STML. In combination with the CEREC Speedfire dentists can expect brilliant restorations in a very short time of production. Let’s discuss some questions:
Does speed sintering effect mechanical and/or optical properties of Katana STML? 
Do we get Zirconia just as translucent as Lithiumdisilicate, but produced faster?
Does a shorter production time influence the schedule in our practices in terms of a direction towards “slow dentistry”?
