Implant Dentistry deals with dental implants or placement of artificial tooth root. This method is adopted by people who have lost a tooth or teeth due to injury, periodontal (gum) disease or some other reason. An artificial tooth root is surgically placed into the jaw to hold a replacement tooth or bridge. Implant Dentistry is generally practiced by surgeons with advance levels of knowledge, expertise, training, facilities and require a high level of accuracy and precision. When compared to other methods of tooth replacement, dental implants are expensive.
