This guide explains reasons for adverse therapeutic outcomes in orthodontic treatment. It begins by looking at tooth and jaw movements associated with increased risk of relapse, then analyzes
retention protocols and presents clinical guides for the use of materials and techniques employed in the fabrication of removable and fixed retainers. Part 1 covers orthodontic retention, with
material on history, the biological basis for relapse, and review and assessment of clinical evidence. Part 2 is devoted to stability and relapse of types of treatment such as Class II
malocclusion treatment, anterior open bite treatment, transverse dimension orthodontic changes, and orthognathic surgery. Part 3 details retention protocols and materials, looking at acrylic
removable retainers, fixed retention in orthodontics, biomaterials used for fixed retainers in orthodontics, and long-term effectiveness of fixed retainers. The guide contains color photos,
b&w medical images, and two-color data and summary charts. Annotation ©2017 Ringgold, Inc., Portland, OR (protoview.com)
