This is a major new work dedicated to the increasingly prominent area of adult orthodontics. Written by renowned contributors from the orthodontic community and beyond, and compiled by a world-class editor, it provides an authoritative resource on the subject, marrying together clinical guidance with a thorough evaluation of the evidence base. The opening chapters provide the context for adult orthodontics, including patient demographics and aetiology, and the book goes on to detail treatment planning considerations, including patient case profiles, suggesting initial outcomes and longer term expectations. Interdisciplinary and multidisciplinary approaches are discussed, including the links between adult orthodontics and periodontics, prosthetics and temporomandibular disorders. The book is accompanied by a website containing further examples of case studies and a wealth of clinical images.
Set to become the gold standard resource on the subject, this book will be invaluable to all those providing orthodontic treatment to adults and those dealing with orthodontics as part of the inter-disciplinary management of the adult dentition.

limitations, a number of papers have reported on metal ion levels in saliva samples from orthodontic patients. Studies have thus found that initial slightly elevated saliva levels of metal ions gradually decline during orthodontic treatment (Kratzenstein et al. 1988; Agaoglu et al. 2001; Gjerdet et al. 1991; Petoumenou et al. 2008) while some have found no significant differences between appliance and non-appliance wearers (Kocadereli et al. 2000). Some authors have hypothesized that a
crown-to-root-ratio through tooth reshaping will not only have a positive impact on the esthetics of the patient’s smile but also on the mechanical functioning of the anterior segment. Intrusion Versus Extrusion When healthy periodontal teeth are orthodontically intruded, their clinical crown length may shorten. So far, it has not been reported if dental intrusion affects their relationship to the periodontal structures in humans, including the possible gain in connective tissue attachment, as
with pocket depth greater than or equal to 6 mm, Corrente et al. (2003) reported that the probing depth was reduced to an average of 4.35 mm following surgical treatment of the pockets and orthodontic intrusion. Radiologically, the horizontal bone defects appeared to have improved by 1.4 mm and vertical defects were filled by 1.35 mm. In the present case of orthodontic intrusion, regenerative techniques were applied (Diedrich 1996). Case 2 This 40-year-old man required ortho-perio-prosthetic
for the canines and incisors. When posterior slenderizing is to be carried out the canines are the last teeth to be stripped. If anterior slenderizing is to be carried out, begin by placing the elastic separator between the canine and the first premolar. For slenderizing in the canine-to-canine region, an archwire with four omega loops is used (Fig. 18.18). That is, a 0.016 inch stainless archwire with omega loops mesially to the second molar tubes and also mesial to the first premolar brackets
binding angle is a product of the bracket size and the wire dimensions, the flexibility of the wire also plays a role. Stiffer wires result in higher resistance to sliding than flexible wires with the same dimensions. Apart from the angle between the wire and the bracket, in other words, the type of the attempted tooth movement (Articolo and Kusy 1999; Thorstenson and Kusy 2002b, 2003a; Kusy 2004), notching may also influence the displacement of the bracket in relation to the wire.
