The modern esthetic dentistry is not only about appearance but also about function and functional durability. For functional durability the knowledge about materials and precision of clinical and laboratory work are essential. The clinical part therefore is more demanding for the clinicians especially if we are using minimal invasive approach. Optical devices and digital scanners are helpful for clinicians to achieve that goal. The digital era in dental laboratory today is something that is more and more present but apart to digital dentistry touch of dental technician in high esthetic region is still necessary. For the communication between dentist and dental technician some new protocols should be considered. We have new possibilities for faster and more accurate communications but also some limitations. It is very important for both sides to simplify protocols with respect to precision, function and esthetics.
