A natural tooth consists of two main components: the crown and the root. The crown is the visible part of the tooth whereas the tooth is located below the gum line, in the jaw bone. Dental implant is the artificial tooth root placed into the jaw bone. It often takes the form of a screw that is composed of titanium or titanium alloy. Dental implants are considered as foreseeable prosthetics applied to replace missing teeth. In the long term, a rate of success exceeding 99% is achieved; and this application has become a routine in dentistry. Application of dental implants generally involves a surgical procedure under local anesthesia in a clinic environment.
