Fabrication of Porous β β -TCP Bioceramics Using Digital Light Processing

β-TCP/PLLA porous scaffold

Background: Ceramic and polymer composite scaffolds are widely used in tissue engineering for bone tissue regeneration. Composite of β-tricalcium phosphate (β-TCP) and poly L-lactic acid (PLLA), due to its biocompatibility and biodegradability, is widely used in bioengineering. However, optimal ratio, porosity and pore size of this kind of scaffolds were not very clear yet. Materials and method...

Proliferation and osteogenic differentiation of human periodontal ligament cells on akermanite and β-TCP bioceramics.

The purpose of this study was to investigate the effects of akermanite as compared to β-TCP on attachment, proliferation, and osteogenic differentiation of human periodontal ligament cells (hPDLCs). Scanning electron microscopy (SEM) and actin filament labeling were used to reveal attachment and growth of hPDLCs seeded on β-TCP and akermanite ceramic. Cell proliferation was tested by lactic aci...

Journal of Craniofacial Surgery Graded Porous β-TCP Scaffolds Enhance Bone Regeneration in Mandible Augmentation

Bone augmentation requires scaffold to promote forming of natural bone structure. Currently most of the reported bone scaffolds are porous solids with uniform pores. The aim of the present study is to evaluate the effect of a graded porous β-tricalcium phosphate scaffolds on alveolar bone augmentation. Three groups of scaffolds were fabricated by a template-casting method: (1) graded porous sca...

Characteristics and osteogenic effect of zirconia porous scaffold coated with β-TCP/HA

PURPOSE The purpose of this study was to evaluate the properties of a porous zirconia scaffold coated with bioactive materials and compare the in vitro cellular behavior of MC3T3-E1 preosteoblastic cells to titanium and zirconia disks and porous zirconia scaffolds. MATERIALS AND METHODS Titanium and zirconia disks were prepared. A porous zirconia scaffold was fabricated with an open cell poly...
