Abstract:

Objective: To prepare the titaniumaaloy(TC4) dental implant by novel 3D printing laser rapid prototyping method and analyze the mechanical properties of 3D printing TC4 material, and to provide foundation for the application of 3D printing technology in the preparation of dental implant.Methods: The digital models of dental implant and the test specimens were set up and the TC4 samples were prepared by 3D printing method. The phase composition and microstructures were observed by XRD,EDS, metaloscope and SEM, the mechanical properties of 3D printing TC4 material for dental implant were detected by microhardness tester and tensile experiment. Results: The microstructure of 3D printing TC4 material was uniform; the tensile strength, yield strength, and extensibility were (1 821.7±146.2) Mpa,(1 355.9±109.2) Mpa, and(31.3±1.8)%, respectively;the vikershardness was 372.93-428.46HV; the mechanical properties of 3D printing TC4 material met the national medical standards of dental implant material.Conclusion: The 3D printing TC4 material could meet the demanding of mechanical properties for dental implant material, and 3D printing technology is promising in dental implant preparation and immediate individual implantation.
