Construction of biomimetic hydroxyapatite bilayer scaffolds via DLP 3D printing for bio-root regeneration.
Digital light processing (DLP) 3D printing of hydroxyapatite (HA) bioceramics offers a promising strategy for fabricating complex, patient-specific bio-root scaffolds with high resolution and bioactivity. However, achieving adequate mechanical integrity while guiding the formation of a periodontal ligament (PDL)-like e...
