Abstract :

Abstract In this study we compare natural frequency in normal teeth and ankylosed teeth. In orthodontic treatment teeth move and rotate is principal. If ankylosis doesn't diagnosed orthodontic treatment will be time consuming or useless. More over in CT scan picture ankylosis is difficult to understand. In this study CT scan picture transform to 3D model via MIMICS software then in Magic it is prepare to analysis after that in SOLIDWORKS alveolar bone and periodontal ligament add to teeth finally in abaqus CAE define density, Poisson ratio, Young modulus for finite element analysis also interaction is defined. Natural frequency for alveolar bone and tooth in separate condition is greater than tooth, alveolar bone and periodontal ligament combined and ankylosed tooth, alveolar bone and periodontal ligament is much greater natural frequency than normal tooth, alveolar bone and periodontal this natural frequency will help to diagnosis ankylosed teeth.
