Neuromuscular adaptations of superficial masseter and anterior temporalis muscle was compared, following treatment of class II div1 malocclusion in growing children, with flexible and rigid fixed functional appliances. It was observed that there was a significant decrease in the muscle activity at 4 weeks with both types of fixed functional appliances. The most significant and prominent difference between the two types of appliances was observed during maximum voluntary clenching, in which, the decrease in the muscle activity was more significant in subjects treated with rigid fixed functional appliance than those treated with flexible fixed functional appliance. This difference was attributed to faster occlusal contacts that were achieved in patients treated with flexible fixed functional appliance. In view of the decreased EMG activity observed in the present investigation, our findings are more consistent with the concept which assigns a major role to the viscoelastic elements of muscle and increased lip strength as mechanism for neuromuscular adaptation, to account for the skeletal changes associated with functional appliance therapy in treating Class II malocclusion.

Orthodontic appliances are the appliances created by orthodontic technology that is used for the treatment of malocclusions. There are two main types of orthodontic appliances: active and functional. They can either be fixed or removable appliances. The active appliance is the tool that is used to apply forces to the teeth in order to change its relation. Some examples of fixed orthodontic appliances are begg light wire appliances, bi helix, self-ligating edgewise appliances, tri helix, pre-adjusted edgewise appliances etc. The functional orthodontic appliance is used to produce orthodontic forces by utilizing the muscle action of the patient and responses of the nervous system. Some examples of fixed orthodontic functional appliances are herbst appliance and twin block appliance. This book provides comprehensive insights into the field of fixed orthodontic appliances. It covers in detail some existent theories and innovative concepts revolving around this domain. Researchers and students in this field will be assisted by this book.

An increasing awareness of the benefits of orthodontic treatment, plus advances in both the sophistication and capability of fixed orthodontic appliances have stimulated a great deal of interest from both dentists and patients. Modern materials offer much improved physical characteristics and the availability of 'aesthetic' appliances has resulted in an increase in the number of patients requesting treatment. However, the readiness with which fixed appliances can now be provided carries with it the danger of their use in inexperienced hands, and the purpose of this book is to provide the newcomer to orthodontics with an understanding of the basic principles involved as well as the mechanisms appropriate for moving teeth with fixed appliances. It also gives general guidance on how to position teeth in order to achieve optimum functional, aesthetic and stable results. Emphasis has been placed on simplicity and clarity, and the book is profusely illustrated with numerous line drawings and colour plates. 'Fixed Orthodontic Appliances' should be essential reading for any graduate commencing orthodontic training, as well as for the interested general practitioner and final year student.
