Evaluation of Mandible Second Molar Uprighting Anchored In Minimplant Using FEM.

Objectives: The biomechanical analysis based on 3D finite element method was applied in this study in order to evaluate the stress distribution simulated model of molar uprighting with the use of a mini -implants as orthodontic anchorage device, which was submitted tensile strength lingual, buccal and associated (buccal and lingual).
Methods: It was elaborated for this study it was made a three-dimensional finite element model, a block containing simulated mandibular posterior region with a second molar mesially angled at 30 degrees, and a self-drilling mini-implant of 1.5 x 2.0 x 8 mm, inserted the distal positioned vertically in relation to the molar angled approximately 10 mm apart.
Results: The results were plotted in color maps, standardized, allowing qualitative comparison between the situations tested. The interpretation criteria were based on analyzes of general displacement maps, Maximum principal, and microstrain, each criterion separately described.
Conclusions: It was found that the three types of load employed were effective for molar uprighting and that the application of force to the tooth tilted bilateral movement generates more uniform.
