No. Dental implants similar to those used in the Dental and Implantology Unit today have been in use for over 40 years now (since the 1960`s) and many millions have been placed and are in use worldwide. In earlier days, implants were normally used in groups to support extensive dental reconstruction including complete upper or lower dental arches. More recently they have also been used to support restorations for small groups of teeth and single teeth. This biotechnology can also be used to support facial prosthesis, artificial limbs and hearing aids.
