Abstract

A two-dimensional, finite element method was used to examine the influence of material selection and suprabony exposure of the implant coating on thermal and mechanical stress distribution. Hydroxyapalite coating reduced the heat conduction to (he surrounding tissue because of its low thermal conductivity. However, Ihermal stress resulted from thermal expansion of the hydroxyapatite and titanium core. This might influence the success of hydroxyapatite-coated implants because the biomechanical roperties of ceramics are so poor for tensile and shearing stress. In addition, this tendency becomes more pronounced when the hydroxyapatite coating surface extends beyond the cortical bone.
