When there is a missing tooth, if there is adequate amount of bone, a dental implant can be placed to replace the missing tooth. Implants are prosthesis with surgical component. Dental implant has multiple componants. In surgical stage a prosthesis is placed in the bone that acts as the root of the tooth. Later on when this prosthesis gets integrated to the bone, this process is called osteointegration, then restorative part will begin and a crown will be added to the implant via a connector. There are different implant systems with different lengths and width that can be used depending on the location of the jaw and amount of the bone.  Some of the most well known implant systems are Straumann, Nobel BioCare, Zimmer.
