Implant therapy is now one of the important dental treatments for reconstruction of oral function. Recently, increasing attention has been paid to several complications related to implant treatment, including inflammatory peri-implantitis. To solve these implant complications and restore missing functions of dental implants as compared to the natural tooth, several efforts have been performed to construct periodontal tissues around the implant, mimicking the anatomical structure of a natural tooth. In this mini review, we will first overview the previously reported studies to form periodontal tissues around the dental implant. Secondly, we will demonstrate our recent trial to construct a periodontium-based implant using cell sheet engineering. We succeeded in the formation of cementum- and periodontal ligament-like tissue around a titanium implant by transplanting a periodontal ligament cell sheet with a surface-modified implant in dogs. Finally, as future directions, some considerations that may be useful to obtain more stable periodontal apparatus structures around implants will be discussed, including artificial formation of the cementum on the titanium surface. This mini review aims to summarize previous trials and recent progress in the formation of implants with periodontium and to provide further insights for innovative implant therapy.
