This finite element study was conducted to calculate the distribution of stresses on root surfaces when a orthodontic force of 2N was applied at different degrees namely 0 degree, 30 degree and 45 degree to the horizontal plane. An in-vitro finite element method was used to construct a three dimensional finite element model of a mandibular arch (without first premolars). Mechanical properties like Young's modulus of elasticity and Poisson's ratio were assigned to the model. To this model an orthodontic force was applied at various degrees on the crown of the tooth model. After the application...

Functional appliances are considered to be primarily orthopedic tools to influence the facial skeleton of the growing child in the condylar and sutural areas. All functional appliances take advantage of interaction between mechanical function and morphologic pattern and use common mechanisms of bone turnover, rhythm, activation, resorption, and formation for their action.These effects are produced because of their ability to alter the stomatognathic muscle balance. For growth modification, functional appliances transmit forces (from muscles or viscoelastic stretch of soft tissue) to the...

Orthodontics and Dentofacial Orthopedics is the first speciality in dentistry. The objective of this textbook of Orthodontics is to provide a comprehensive review of this subject that is accessible to students especially post-graduates. Every-day we learn something new through our clinical exposure in this field. With time and experience orthodontists learn many technique adjuncts that work for them and which facilitate the clinical treatment of their patients. A number of these adjuncts are published in different journals. In this book I tried to collate some of these clinical tips. Our goal...

Condylar head inclination proved to be the most significantly correlated condylar characteristics to facial morphology. Hypodivergent pattern is dominant in Class II malocclusion. Symphysis width dimension also vary in different Class II malocclusion.SBL-PNS, Y -axis, Facial -Axis, PFH/AFH X100, Bjork sum and Symphseal width are significant parameters which discriminate between groups. Horizontal facial morphology was seen in 45 % of cases, vertical 8.3% and normal was 46.7%. Facial types of the Class II patients vary and it depends on the position of the condyle in the fossa. It can be...
