Acknowledgements This edition of the TipBook has been written with the guidance and backing of university lecturers and scientists, specialists and scientific consultants. Our protocols, and the findings that support them, originate from university theses and international publications, which you will find referenced in the bibliography. We have of course gained tremendous experience over the last thirty years from the dentists worldwide who, through their recommendations and advice, have contributed to the improvement of our products. But our special thanks go to each Satelec user who shows faith in us, each time they choose one of our products. Gilles Pierson President
