Abstract 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.

Enviro Dental Journal dentaljournal.org Vol. 02, No. (1) 2020, Pg. 04-08 INTRODUCTION Since its inception in 1960 Titanium implants (Ti) have dominated oral implantology. Titanium can be found in different combinations with other metals for use in dentistry. Titanium dental implants, considered gold standard in oral implantology and have stood the test of time in restoring partial and complete edentulism. They are also well suited to use as orthodontic anchors. The survival rate of titanium implant restorations is approximately more than 90% in different clinical studies. 1 Titanium is dark greyish colour and gives unaesthetic huethrough the peri-implant mucosa. This situation becomes more pronounced in the presence of a thin mucosal biotype, gingival recession, unfavourable soft tissue conditions and is of great concern in maxillary anterior region. 2 Thus, patients’ high
