Orthodontic Mini-implant Clinical Handbook (eBook)

Richard Cousley is a Consultant Orthodontist at the Peterborough and Stamford Hospitals NHS Foundation Trust, and in private specialist practice. He is the Associate Editor for the Journal of Orthodontics and a Membership in Orthodontics examiner for the Royal College of Surgeons (England). Richard has pioneered mini-implant usage in the UK since 2003 and designed the Infinitas mini-implant system. He has published numerous clinical papers on bone anchorage techniques, and has been an invited lecturer at British, European and American orthodontic conferences and university programmes. Most recently he became the UK clinical advisor for an orthodontic aligner company.

"I strongly recommend this book to all cliniciansinterested in introducing skeletal anchorage into their practice.The book is competitively priced, particularly when considering theamount clinical material provided." (EuropeanJournal of Orthodontics, 2 October 2013)

"I have no hesitation in recommending this book as anessential read for orthodontic specialty trainees who may benefitfrom the pro-gressive approach." (BritishDental Journal, 28 September 2013)
