Investigation on 3D printing ZrO2 implant abutment and its fatigue performance simulation
Source abstract
Abstract
Abstract The zirconia (ZrO2) ceramic dental implant abutment was prepared by DLP (Digital Light Processing) 3D printing technology. The effect of different heat treatment parameters on the sintering quality of ZrO2 was studied. According to TG-DSC, XRD, Raman, SEM and other characterization methods, it could be determined that best sintering parameter was set at 1450 °C for 1.5 h. The final product has a good morphology without holes and other defects, and the relative density is 99.48%. The ZrO2 samples printed in different directions have obvious anisotropy. The three-point bending strength of the sample in the horizontal direction is better than that in the vertical direction, and the strength is 600 MPa. The fatigue load simulation results show that the smaller the pre-angle is, the smaller the maximum stress is and the higher the safety factor is.
