Effect of particulate and putty-like tricalcium phosphate-based bone grafting materials on bone formation, volume stability and osteogenic marker expression after bilateral sinus floor augmentation in humans

摘要

Six months after implantation of both TCP-based graft materials bone formation and matrix mineralization were still actively progressing in the tissue surrounding the TCP particles. The TCP putty material displayed more favorable surgical handling properties compared to TCP-G without the Hyac hydrogel matrix having any adverse effect on bone formation, bone tissue maturation or graft volume stability. Consequently, TCP-P can be regarded as excellent grafting material for sinus floor augmentation in a clinical setting.
