Offers the very latest on the theory and practice of integrating mini-implant techniques into clinical practice This all-new second edition of The Orthodontic Mini-implant Clinical Handbook provides a thoroughly revised and expanded update to the theoretical and practical aspects of using mini-implants in orthodontic practice. Taking a practical step-by-step approach with hundreds of clinical images, it presents updated clinical techniques and new clinical cases, covering all topics of importance for utilising mini-implants. It also includes a new chapter on mini-implant anchored maxillary expansion appliances. It begins with a chapter that looks at mini-implant principles and potential complications, before moving onto clinical and design factors for maximising mini-implant success. Other chapters cover incisor retraction; molar distalisation and protraction; intrusion and anterior openbite treatments; bone anchored rapid maxillary expansion; orthognathic surgical uses; and ectopic teeth. Provides a comprehensive guide to both theoretical and practical advice for the use of mini-implants in orthodontic practice Covers updated clinical techniques and new clinical cases Presents a new chapter on mini-implant anchored maxillary expansion appliances Takes a highly illustrated step-by-step approach ideal for clinical practice The Orthodontic Mini-Implant Clinical Handbook is an essential resource to orthodontists, maxillofacial surgeons, practicing dentists, and anyone with an interest in mini-implant skeletal anchorage.
