Introduction: Maxillary molar intrusion has been regarded as one of the difficult orthodontic tooth movements when prevention of undesirable movement and root resorption are empirically considered. The purpose of the study was to evaluate the effects of various intrusive forces on maxillary first molar using - finite element method. Materials and Methods: Geometric model of maxillary 1 st molar was generated using software ANSYS Workbench 11. The loading condition was designed to mimic conventional orthodontic tooth movement which was subjected to three different intrusive force magnitudes via 150 g, 180 g and 210 g and was put through finite element analysis (FEA). Results: The results were suggested high stress concentration at furcation level of the tooth and compression was seen in apical third of root area of the periodontal ligament (PDL) except in palatal side of palatal root. Conclusion: The furcation area of the tooth is most prone to root resorption and compression was observed in apical third of all root area of PDL except in palatal side of palatal. Displacement at cervical region in palatal side of PDL, at central fossa of the tooth and at the cervico-palatal region of alveolar bone. The results gained through FEA should be integrated with the clinical experiences to maximize accuracy.
