Implant therapy is a widely used treatment modality for completely and partially edentulous patient. It gives excellent long term results and has made practice of dental implantology astonishingly widespread. Titanium dental implants have proved to be successful means of prosthetic rehabilitation for more than six decades. Recently, ceramics have been proposed as an alternative to titanium. Zirconia implants with better aesthetics, mechanical and biological properties are showing a promising future in dental implantology. This narrative review analyses the evidences to compare titanium and zirconium implant in a systemic manner. The paper includes the mechanical, biological and clinical consideration involving both implant materials.
