Dental medicine, as a clinical and scientific discipline, is followed by the rapid development of dental technology. Materials used in dental medicine have a long history. Starting with beeswax, "Plaster of Paris", thermoplastic materials, hydrocolloid and elastomeric materials, to the 20th century’s 3D digital impressioning systems. Digital technologies represent the majority of technological processes in the development of prosthetic devices. Global leaders, which set high standards in digital dentistry, have become the companies 3Shape, CEREC and Amann Girrbach. The advanced techniques of optical scanning and completion of other imaging technologies such as CBCT's, MRI, ultrasound, and similar, allow us to produce digital impressions thoroughly comparable to the conventional ones. Traditional way of impressioning can cause traumatic and stressful situations for both the patient and the dentist. With digital impressioning we can avoid these situations, moreover it can eliminate several procedural steps in dental work. The use of digital impressioning has reduced the number of repeated impressions and restoring works, and generally it has increased the overall dental efficiency. Furthermore, digital technology could be applied in the processes of making a custom tray, which could be significantly improved by comparison with conventional procedures and technologies. However, function impressions are still indispensable at the moment.
