Purpose: The effects of a recombinant human bone morphogenetic protein-2/7 (rhBMP-2/7) heterodimer and a RADA16 (Ac-RADARADARADARADA-CONH2) hydrogel scaffold on bone formation during distraction osteogenesis were evaluated.
Materials And Methods: Forty New Zealand white rabbits, which underwent mandibular lengthening, were randomly divided into 5 groups. One group served as the control group.
