ソケットシールド技術を用いた歯科インプラント周囲組織における濃縮成長因子の効果

The present case report describes the use of radiographic techniques to assess the quality and quantity of the bone surrounding the dental implants treated with concentrated growth factor (CGF). Intraoral examination revealed a cracked, root canal-treated anterior tooth (#12). After discussing the surgical protocol, including its advantages and limitations, socket shielding was performed, implant osteotomy was prepared, and CGF was placed. Assessment of crestal bone levels, volume, and density was conducted at baseline and at the 9-month follow-up after implantation. Soft-tissue parameters were also evaluated at 3 and 9 months postimplantation. At recall, both bone quality and quantity had increased, and crestal bone levels remained stable. No changes were observed in soft-tissue parameters between the pre- and postimplantation phases. These findings suggest that CGF can promote the regeneration of both hard and soft tissues by enhancing bone quality and quantity and by improving the peri-implant soft-tissue environment.
