Dental implants have been a tooth replacement option for almost 50 years. They are now considered to be one of dentistry’s standard therapies. Furthermore, implantology is based on a solid scientific foundation of research and experience. A natural tooth consists of a crown and a root. A dental implant is an artificial dental root which is positioned directly in the jawbone to replace a missing tooth. Over a period a few weeks to several months, the dental implant bonds with the bone (osseointegration). During osseointegration, bone cells form new bone around the implant. This new bone develops a firm anchor for the implant. The bonding of the implant with the bone is a prerequisite for achieving a strong foundation for the artificial crown. After healing, the implant acquires the same function as that of a natural tooth root. Just like a natural root, implants can prevent bone recession in edentulous jawbone, compared to conventional bridge and prosthetic restorations. This means that dental implants also serve a preventative function.
