Polyglycolic acid-collagen tube combined with collagen-binding basic fibroblast growth factor accelerates gait recovery in a rat sciatic nerve critical-size defect model.

Journal of Biomedical Materials Research. Part B - Applied biomaterials, 2020
Several nerve conduits have been investigated for their potential as alternative sources of autografts for bridging neural gaps. However, autologous nerve transplants remain the most effective for nerve repair.

3D Printing in Treatment of Soft, Hard, and Critical-Sized Oral and Maxillofacial Tissue Defects

2021
Intraoral scanning, computer-aided object designing, and 3D printing, collectively known as digital workflow, are gradually becoming an indispensable procedure in modern dentistry. However, this approach has not yet been extensively investigated for the fabrication of oral and maxillofacial tissue substitutes.

The effect of print size on reading rate for adults and children

Australasian journal of optometry, The, 1994
Print size is one of the numerous factors affecting reading rate. The purpose of this study was to investigate the print sizes which give maximum reading rates for adults and children. Using a forced scrolling technique to move the reading material and

Advanced reconfigurable scaffolds fabricated by 4D printing for treating critical-size bone defects of irregular shapes

Biofabrication, 2020
Abstract While scaffold-based tissue engineering has been widely used to treat bone critical-size defects, challenges such as implantation of scaffolds in defects with irregular shapes and implantation of scaffolds through minimally invasive surgery remain in the tissue engineering field. Customized bioactive bone

Regeneration of critical‐sized mandibular defect using a 3D‐printed hydroxyapatite‐based scaffold: An exploratory study

Journal of Periodontology, 2020
AbstractBackgroundThree‐dimensional (3D) printing has become an available technology to fabricate customized tissue engineering scaffolds with delicate architecture. This exploratory study aimed to evaluate the potential of a 3D‐printed hydroxyapatite‐based scaffold as a biomaterial for obtaining guided bone regeneration (GBR) in vivo.MethodsScaffolds ...

Three‐dimensionally printed polyetherketoneketone scaffolds with mesenchymal stem cells for the reconstruction of critical‐sized mandibular defects

The Laryngoscope, 2017
ObjectiveAdditive manufacturing offers a tailored approach to tissue engineering by providing anatomically precise scaffolds onto which stem cells and growth factors can be supplied. Polyetherketoneketone (PEKK), an ideal candidate biomaterial, is limited by a poor implant–bone interface but can be functionalized with adipose‐derived stem cells (ADSC ...

A fully ingrowing implant for cranial reconstruction: Results in critical size defects in sheep using 3D-printed titanium scaffold

Biomaterials Advances, 2022
Current alloplastic materials such as PMMA, titanium or PEEK don't show relevant bone ingrowth into the implant when used for cranioplasty, ceramic implants have the drawback being brittle. New materials and implant designs are urgently needed being biocompatible, stable enough for cranioplasty and stimulating bone formation.
