This book is a comprehensive, state of the art guide to the contemporary diagnosis of temporomandibular disorders (TMDs) that will help to compensate for the frequent lack of experience and inadequate training among health professionals who encounter patients with jaw joint problems. The opening section describes the whole patient philosophy essential for treatment success, examines ethical and legal considerations, and discusses all aspects of anatomy. Pathophysiology, clinical assessment, and imaging evaluation, including by means of modern MR imaging and CBCT, are then considered in detail. Finally, the diagnostic criteria for the full range of TMDs are thoroughly explained and the urgent need to appreciate temporomandibular disorders as the chronic pain conditions they are is addressed. Complementary volumes are devoted to non-surgical treatment of TMDs and to total temporomandibular joint replacement and other surgical procedures, respectively.
