Niobium in Oral Implants

Since Prof. Branemark discovered the phenomenon of osseointegration of pure titanium materials in 1952 and used it as a basis for the fabrication of implants, people have not ceased their efforts and pursuits to perfect the performance of implants. Although titanium and its alloys have excellent biocompatibility, corrosion resistance and mechanical strength, and are the most widely used implant materials in clinical practice, their success rate in clinical application was once affected by the mismatch of elastic modulus with bone tissue and low osseointegration strength. Improving the comprehensive performance of titanium-based implants has been one of the hotspots of research, and among the achievements that have been made, the development of B-type titanium alloys (the implant's own material) and the progress of surface modification are particularly prominent. Niobium metal, as a highly biocompatible high-melting metal, is increasingly being used for the improvement and surface modification of implant self-materials.
