New fiber reinforced composite material for custom-made craniofacial implants

Lazar MA

University of Medicine and Pharmacy, Romania

T

he aim of the present research was the elaboration and

the characterization of new fiber-reinforced composites

(FRCs) that will serve cranial bone reconstruction, particularly

in thecases of large bicortical calvarial defects. Four new

formulations of FRC were obtained using polymeric matrices

(combinations of monomers bisphenol A glycidylmethacrylate

(bis-GMA), urethane dimethacrylate (UDMA), triethylene

glycol dimethacrylate (TEGDMA), hydroxyethyl methacrylate

(HEMA)) and E-glass fibers (300g/mp). Every FRC contained

65% E-glass and 35% polymeric matrix. The newmaterials were

extensively characterized and tested for their chemical, phisical

and biological properties, using well estabished methods

(high performance liquid chromatography, scanning electron

microscopy, atomic force microscopy, X ray diffraction, flexural

and compression strength tests, citotoxicity and implantation

tests) and the best formulation was selected. The selected

material was used to produce personalized implants for the

reconstruction of critical size defects of rabbit calvaria. Local and

general impact upon animal health, quality of reconstruction,

bone and dura reaction to the material were investigated by

means of clinical, imaging and histological analysis. The results

of our research pointed out that the FRCs based on UDMA resin

reinforced with E-glass fibers could be an optimized alternative

to the similar nowadays available materials used for the

reconstruction of bone defects in the cranio-maxillofacial area.
