Finite element analysis of the mandible with implant applied the force from chin
Objectives To investigate the force effect of implant in the mandible, the stress changes of the mandible and the first molar for mandibular dental implants were analyzed with finite element method when the chin was impacted with 100N horizontal force. Methods The finite element models of mandible missing the first molar and the dental implants were established with CT data of a man head. The mandibular boundary constraints were built, and the chin was impacted with 100N horizontal force. The stress change of the whole mandible and the regional of mandibular first molar dental implants were recorded and observed. Results After the 100N external force being imposed on the mentum, stress changes showed that the lowest values on the section area of the right implant were 9.005 Pa in 10.82 mm and 9.067 Pa in 86.38mm, and the maximum stress was 94.962 Pa in 52.97 mm. For the left first molar, the changes showed that the lowest values were 18.227 Pa in 10.37 mm and 8.867 Pa in 83.82 mm, and the maximum stress was 93.912 Pa in 54.66 mm. The stress change of the overall mandibule recorded showed that the mentum stress area was the largest, with peak reaching 260.524 Pa. Conclusion The implant of first molar does not affect the normal mechanical behavior of mandible.
