ABSTRACT
BACKGROUND:
The tissue-engineered scaffold, as a substitute of autogenous bone graft, plays an important role in bone repair. In the meanwhile, three-dimensional (3D) printing technology has obtained more attention because of its accurate adjustment.OBJECTIVE:
To review the in vitro or in vivo studies on the 3D-printed scaffolds applied in bone repair, thus providing basis for clinical research.METHODS:
The first author searched the PubMed database using the English keywords of tissue engineering, bone,three-dimensional printing, scaffold for pertinent articles addressing 3D-printed tissue-engineered scaffolds.RESULTS ANDCONCLUSION:
There are plenty of studies on 3D-printed tissue-engineered scaffolds, and recent research focuses on the material selection and surface modification. The appropriate porosity is vital, and with the development of manufacturing technology, each property of the scaffold is improved, and composite materials prevail gradually. All above improvements enhance the mechanical property and promote cell adhesion and proliferation.Furthermore, the surface modification promotes the implant-bone interaction. In vivo and in vitro research both indicate that composite materials with the surface coating of bone induction can improve the scaffold performance and osteogenesis.
