Evaluation of stress distribution in bone at varying lengths and diameters of micro-implant

ABSTRACT:
Introduction: Temporary Anchorage Devices play an important role to overcome the limitations of conventional anchorage control in fixed orthodontic practice.
Aims and Objectives: To evaluate the stress distribution in bone at varying lengths and diameters of the micro-implant.
Material and Methods: 3-D Finite element models of maxilla, mandible, and micro-implants with varying lengths and diameters were generated. The micro-implants were inserted 90ᵒ to the bone surface. A force of 200 g was applied from the micro-implant to the power arm. Stress distribution and its magnitude were then analyzed with a 3-dimensional finite element analysis program.
Results: Increased diameter of micro-implant, showed significant negative correlation with the stress generated. The maximum von Mises stress was found for implant of diameter 1.2 mm and least for implant of diameter 1.8 mm.
Conclusion: Increasing the diameter of the micro-implant reduces the stress concentration in bone, thereby increasing the likelihood of implant stabilization.
