Abstract:
OBJECTIVEThe aim of this study was to investigate how to model an accuracy 3-dimension Finite Element Analysis (3D-FEA) model.
METHODSBased on computed tomography (CT) scan data of a woman, a 3D finite element model of the first molar on the left was rebuilt by computer imagines process and computer aided design (CAD). Analysis of the stress distribution on a cylinder dental implant and in the bone around it was conducted.
RESULTSThe stress distribution showed extremely asymmetry in bucco-lingual section: stress concentrated on the lingual side of the mandible; stress mainly was tensile in buccal side, and on the contrary compressive in lingual side.
CONCLUSIONThe results were more reliable because this model more really displayed the mandible.
