It may be defined as tooth root designed to fill spaces due to missing teeth and generally made of titanium.
Implants basically consist of three parts; the implant is generally made of titanium and it is the part within the bone. Abutment (denture basis): it is screwed on the implant united with the bone and provides basis for the denture (porcelain, zirconium etc.) which is the third structure.
Today, dental implants are made of titanium. Titanium is a material which has the feature to be able to unite with bone without any allergic reaction in body and strength which provides resistance to chewing forces.
