BackgroundChronic alcohol consumption is a known limiting factor for bone healing. One promising strategy to improve bone augmentation techniques with Bio-Oss^® in oral and maxillofacial surgery might be the supportive application of platelet-concentrated biomaterials as platelet-released growth factor (PRGF). To address this matter, we performed an in vitro study investigating the protective effects of PRGF and Bio-Oss^® in ethanol (EtOH) treated osteoblasts.MethodsThe SAOS-2 osteosarcoma cell line, with and without EtOH pretreatment was used. The cell viability, proliferation and alkali phosphatase activity (ALP) after application of 0%, 5% and 10% PRGF and Bio-Oss^® were assessed.ResultsThe application of PRGF and Bio-Oss^® in EtOH impaired osteoblasts showed a significant beneficial influence increasing the viability of the osteoblasts in cell culture. The synergistic effect of Bio-Oss^® and 5% PRGF on the proliferation of osteoblasts was also demonstrated. Bio-Oss^® only in combination with PRGF increases the alkaline phosphatase (ALP) activity in EtOH pretreated cells.ConclusionsThese results indicate that the simultaneous application of PRGF and Bio-Oss^® inhibits EtOH induced bone healing impairment. Furthermore, in the cells, PRGF induced a protective mechanism which might promote bone regeneration.
