Evaluation of Bioactive Glass as a Bone Graft Extender in Sinus Elevation Surgeries

This study evaluated histologically and radiographically sinus elevation surgeries using PerioGlas (PG) in combination with autogenous bone (AB) or freeze dried bone (FDB).Methods: Thirty-two elevations were done in 27 patients with five patients receiving bilateral elevation. PerioGlas was mixed with AB or FDB in a 1:1 ratio. All sinus elevation and implant surgeries healed uneventfully. Histologic samples were obtained as part of the subsequent implant placement procedure. A total of 37 Bio-Lok implants, 10-13 mm in length were implanted.Results: All implants osseointegrated and successfully restored. Average bone gain at 6 months was 5.6 mm for PG + AB and 7.4 mm for PG + FDB with no clinically significant difference between either. PerioGlas, in addition to its osseous regenerative properties, displays excellent handling characteristics and with its osteostimulatory properties, can be used as a bone graft extender for sinus elevation surgeries.
