Abstract

Statement of Purpose: Autologous bone grafts remain the gold standard for craniofacial reconstruction despite limitations of donor site availability and morbidity. A myriad of commercial bone substitutes and allografts are available, yet no product has gained widespread use due to inferior clinical outcomes. The ideal bone substitute is both osteoconductive and osteoinductive. Craniofacial reconstruction often involves irregular three-dimensional defects, which may benefit from malleable or customizable substrates. "Hyperelastic Bone" (HB) is a 3D-printed synthetic scaffold, composed of 90% by weight hydroxyapatite (HA) and 10% by weight poly(lactic-co-glycolic acid) (PLGA), with inherent bioactivity and porosity to allow for tissue integration. This study examines the capacity of HB for bone regeneration in a critical-sized calvarial defect.
