Abstract:

The purpose of this study was to design porous implants with particular structure and evaluate their biomechanical behavior. Thus, a segmented porous dental implant (SPDI) was designed and manufactured by 3D Printing and computer numerical control (CNC) composite machining technology. The FE analysis was used to investigate its static mechanical property. Fatigue test was performed to verify its fatigue life. Resonance frequency analysis and pull-out tests were carried out to study its primary stability. Results indicated that better stress distribution was observed for SPDI. Fatigue test showed that no fracture or failure occurred in SPDI samples after 8 million cycles. The average implant stability quotient (ISQ) values of the SPDI inserted into the porous and denser artificial bones were 68.7 and 73.0 respectively. The average maximum pull-out force of SPDI extracted from the artificial bones was 347.5 N. This study provided a new structural design and manufacturing method for porous implant. The results suggested that the novel porous implant obtained good mechanical adaptability and primary stability.
