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.
