Acknowledgements

We are extremely grateful to our many colleagues who have been kind enough to source and donate figures used in this book. We have acknowledged individual sources in the relevant figure legends, but are particularly grateful to Christoph Huppa, Evelyn Sheehy and Zahra Kordi who made great efforts on our behalf to locate relevant clinical pictures. We would also like to thank a number of people who kindly proof-read and made numerous comments on the text within various chapters; Raymond Edler and Sue Mildenhall for the relevant sections on contemporary treatment of cleft palate; Peter Kesling, who cast his expert eye over sections relating to Tip-Edge mechanics; Eric Whaites, who advised on the complex and controversial subject of radiation protection and Oliver Bowyer, who read several draft chapters and gave relevant feedback from the perspective of an orthodontic trainee. We would like to thank James Abbott who constructed many of the removable appliances illustrated in the book and Padhraig Fleming, Paul Scott and Saba Quereshi for numerous figures and their support.

At Elsevier, we would like to thank Michael Parkinson, who had enough faith in our original proposal to commission the book in the first place; our development editors, Hannah Kenner and Carole McMurray who cheerfully dealt with the original manuscript and our project manager Bryan Potter, who set the book up and happily accommodated our multiple last-minute changes.

Finally, we would like to acknowledge the immense help and assistance provided by our wives Jackie and Sarah. Not only for their expert proof-reading and checking of all things related to orthodontic theory (Jackie) and English grammar (Sarah); but also for putting up with our three-year preoccupation with this project—particularly as two (soon-to-be three) children have been born during the writing and production of this book.
