In this study, in vivo performance of novel resorbable bone wax based on a miscible blend between PEG-PPG-PEG copolymer mixtures and pregelatinized starch at 0 and 25 percent by weight including hemostasis, tissue reaction and bone healing in a non-critical size tibia defect model were assessed and compared with commercial non-resorbable bone wax. Systemic reaction was evaluated by blood chemistry while local reaction, bone quantity and quality were evaluated by microcomputed tomography (microCT) and histology analyses. It was observed that the resorbable bone waxes did not show any adverse systemic reaction and resorbed from the defects within approximately 2 days after application.
