Interaction of bone-dental implant with new ultra low modulus alloy using a numerical approach

摘要: Although mechanical stress is known as being a significant factor in bone remodeling, most implants are still made using materials that have higher elastic stiffness than of bones. Load transfer between the implant and surrounding bones much detrimental, osteoporosis often consequence such mismatch. The concept biocompatibility has now been considered for more decade. However, it limited by choice materials, mainly Ti-based alloys whose properties too far from cortical bone. We suggested bulk material relation with development new beta titanium-based alloy. Titanium suitable biocompatible metal, beta-titanium metastable TiNb exhibit very low apparent modulus related to presence an orthorhombic martensite. purpose present work investigate interaction occurs dental 3D finite element models adopted analyze behavior bone-implant system depending on implant, different types geometry, friction force, loading condition. geometry mandibular incisor Occlusal static forces applied implants, their effects bone-metal interface region assessed compared bone/bone configuration. This shown induces distribution closer actual physiological phenomenon, together better jump along interface, regardless design.
