The sonic technique represents one of the most advanced innovations in the field of dental prosthesis, offering a highly precise and minimally invasive approach. This two-day course is designed to offer participants a comprehensive overview of the use of sonic instruments in prosthetic preparation, from theory to clinical practice. During the course, the advantages of sonic technology will be explored, such as greater precision in preparation margins, reduced stress on dental tissues, and improved operational efficiency compared to traditional techniques. Participants will have the opportunity to attend practical demonstrations and practice firsthand on simulator models, learning the best techniques for high-quality prosthetic preparations. A special focus will be given to the selection and use of sonic inserts, as well as the optimisation of clinical protocols to integrate this technology into daily practice. At the end of the course, participants will have acquired practical skills and theoretical knowledge to fully benefit from the potential of the sonic technique in dental prosthesis.
