The Orthodontic Mini-implant Clinical Handbook

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.
