Ti계 생체이식금속의 구성 성분에 따른 물성과 세포독성에 관한 연구+

Today, dental implants are acceptable alternative capable of providing bone-anchored fixed prostheses for improved quality of life and self esteem for many patients. Research advances in dental implantology have led to the development of several different types of materials and it is anticipated that continued research will lead to advanced dental implant materials. Currently used pure titanium has relatively low hardness and strength which possibly limits its ability to resist functional load as a dental implant. Ti 一 6A1—4V also has potential problems such as corrosion resistance, bone biocompatibility etc. The carefully selected Zr, Nb, Ta, Pd, In constituents could improve mechanical strength, corrosion resistance and biocompatibility compared to that of currently used implant metals. On the basis of the totality of the data from our several experiments, it can be concluded that new titanium alloys contained Zr, Nb, Ta, Pd, In are able to provide improved mechanical properties, corrosion resistance and biocompatibility to warrant further investigation of it’s potential as a new biomaterials for dental implant.
