Objective: To establish a three-dimension finite element model for orthodontic anchorage microimplant and analyze the influence of different titled angle on the biomechanical characteristics of orthodontic anchorage implant-bone interface. Methods: Use ANSYS (Analysis System) finite element analysis software to perform the finite element modeling of the micro-implant with 7 different tilted angle, including 30°, 40°, 50°, 60°, 70°, 80°and 90°. A simulated orthodontic force, which was 200 grams, was loaded mesiodistally to the mathematical models, the stress and displacement distribution on the implant-bone interface was analyzed. Results: As the titled angle increased, the Von-Mises stress at the cervix of the implants were 1.0792Mpa, 1.0104Mpa, 0.8848Mpa, 0.8181Mpa, 0.7583Mpa, 0.6339Mpa and 0.5608Mpa while the displacement were 5.5513μm, 4.9900μm, 3.7419μm, 3.1264μm, 2.5874μm, 1.3624μm and 0.8027μm. Conclusion: The microimplant can be safely loaded with 200 grams mesiodistal orthodontic force. The increase of the titled angle can efficaciously enhance the implant's ability of bearing mesiodistal orthodontic force. Thus we should choose the vertical angle when the micro-implant is embedded.
