Implantology is a field that is always evolving as fresh research findings help us comprehend the biologic principles that govern the creation of a dynamic interface between living tissue and artificial structures. The potential for implant failure is a serious issue for implantologists, and understanding this inevitable fact is crucial for a good clinical practise. It can be expensive in terms of time and money to deal with complications and loose implants. It is advisable to carefully analyse a wide range of aspects before implant placement, including systemic and local host conditions, as well as the design of a prosthesis. Whenever possible, treatment planning decisions should be based on projections of the greatest long-term success. Failures have been related to biologic, microbiological, biomechanical, biomaterial implant surface treatment and characteristics. Many factors are attributed to immediate failure of the dental implant either directly or indirectly.
