Book Description
The purpose of this research was to verify a proposed closed-form solution which solved for the reaction forces on a patient's teeth during orthodontic treatment using finite element analysis. The results were verified by constructing a progressive series of models in Abaqus and comparing the calculated displacements to their closed form solutions. The final orthodontic model featured a Nickel Titanium archwire subjected to the fourteen reaction forces obtained from the proposed closed form solution. Elastic and plastic behavior was considered through use of a bi-linear model. The displacements obtained from the FEA model were compared to the actual displacements measured between the start and end positions of the patients teeth.The error between the analytical and numerical solution in the elastic regime was miniscule. The graphs of displacement obtained from the closed form and FEA solutions overlapped each other. The error between the analytical and numerical solution in the plastic regime was found to be approximately 25%.The results of this research is the validation of the closed form solution using a modified form of Castigliano's Theorem, as well as the establishment and visual representation of the relationship between applied force and orthodontic displacement.

Book Description
One of the governing ideologies in orthodontics is gradually imposing remodeling, which involves progressive and irreversible bone deformations using specific force systems on the teeth. Bone remodeling results in the movement of the teeth into new positions, with two tissues having a major influence along with it: the periodontal ligament and the alveolar bone. There is a definite connection between the mechanical, biological and physiological reactions to the orthodontic forces. The development of the Finite Element Analysis and administration of this new age computer-aided method in orthodontics applies to this chapter. Finite Element Analysis is a computational procedure to calculate the stress in an element, which can show a model solution. The FEM analyses the biomechanical effects of various treatment modalities and calculates the deformation and the stress distribution in the bodies exposed to the external forces. The ideology behind this particular chapter is to introduce this scientific approach to the orthodontist and to reinforce the effects and advantages to the ones who are already aware of the same. In this chapter there is a detail discussion and explanation systematically on Finite element analysis method and its application strictly in and around orthodontics without much deviation from the subject.

Book Description
In the field of dentistry a variety of sophisticated procedures and equipment are used, which are based on basic concepts of engineering. One such important procedure is the Finite Element Method . It's a procedure for the numerical solution of the equations that govern the problems found in nature. It is an engineering method for the numerical analysis of complex structures based on their material properties to determine the distribution of stress and strain when such structures are subjected to forces by means of discretizing a continuous structure into sub-domains called Finite Elements. It also makes it possible to model cranio-facial and dental structures to study their biomechanical behaviour without using any invasive techniques. It is helpful in improving different types of appliances, techniques, designs, etc. in the orthodontic practice such as brackets and their attachments, arch wires, loops, and adjuncts such as the headgears and transpalatal arch. This powerful design tool has significantly improved both the standard and methodology of the design process in many orthodontic applications.
