Innovation requires not only developing or improving materials, but also providing the state of the art knowledge to select and use that materials in the best possible way. GC regularly organizes qualitative education courses for dentists and dental technicians at the GC Europe Campus Meeting and Education Centre. On the 16th and 17th of January, GC held the 2nd ‘Train the trainer for indirect restorations’ in order to coach dentists and opinion leaders towards their future luting trainings.
