Maxillary sinus elevation and simultaneous implant placement using PRGF (plasma rich in growth factors), hydroxyapatite and allogenic graft. Seven year case report

Resumen

Maxillary sinus floor elevation is a predictable surgical procedure meant to vertically increase the amount of bone in the posterior region of the upper jaw to enable placement of a prosthetic rehabilitation device supported by implants. The aim of the present article was to describe elevation of the maxillary sinus fl oor using plasma rich in growth factors, absorbable hydroxyapatite and bone allograft as sub-antral graft materials with simultaneous placement of two surface treated implants (Osseotite, 3i). The present article also reported clinical and radiographic results obtained at seven days, six months and seven years after the surgery. From the clinical and radiographic standpoint suitable healing was observed. The surgical procedure used in the present clinical case was considered a suitable option to place implants in atrophic maxillary areas.
