LEARNING OUTCOMES
The course aims to the acquisition of the necessary scientific and applied knowledge which will enable students to design and fabricate fixed dental prostheses and in particular a variety of fixed all-ceramic restorations in accordance with the current scientific trends and materials.
Upon completion of the course, students will:
- know the contemporary all-ceramic systems and their use
- know the fabrication steps of the most widespread contemporary all-ceramic restorations in both theory and practice.
- know which steps are of their own responsibility and how to cooperate harmoniously with the dentist.
- know all the variations of the contemporary all-ceramic restorations that are currently part of the everyday dental technology practice.
