FRIARIT^®-2 BoneCondenserを用いた上顎洞底挙上の1例

抄録

The socket lift technique, a version of osteotome sinus floor elevation (OSFE), in which the sinus floor in raised through the implant socket and bone graft is added, is simpler, less invasive, and requires less quantity of bone graft material compared with previous sinus lift methods, in which the access is obtained through the lateral wall of the alveolus. This report presents a case of oral rehabilitation performed in the edentulous region of teeth Nos 25 to 27 using FLIALIT®-2 (F-2) with a socket lift technique in proportion to Summers osteotome sinus floor elevation technique.
Case report:A 59-year-old female presented for implantology in the maxillary left posterior segment of teeth Nos 25 to 27. Implant sockets were prepared using BoneCondenser and the sinus floor was partially malleted upward. The space created between the raised sinus membrane and the alveolus was filled with bone graft material, and then 3 F-2 implant bodies were inserted. The bone graft was harvested from the buccal region along the oblique line of the mandible.
Prognosis: After 6 months of healing, prosthetic rehabilitaion was accomplished with the PMS method. A dental X-ray taken 4 months after operation revealed radiopacity of the bone graft. Good functional rehabilitation was also obtained at 3 months after prosthesis placement.
