Implantology is the study and practice of placing dental implants. Any licensed dentist with proper training in implant dentistry can be considered an implantologist. A dental implant (also known as an endosseous implant or fixture) is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, facial prosthesis or to act as an orthodontic anchor. Despite improvements in dental care, millions of people suffer tooth loss, mostly due to tooth decay, periodontal disease, or injury. For many years, the only treatment options available for people with missing teeth were bridges and dentures. But, today, dental implants are available. Implantologists are specialists in dental implants or replacing tooth roots. Dental implants are small titanium screws which are fixed into the jawbone by an implantologist or implant dentist. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth.
