    Accuracy of additive technologies in dentistry
    Zehni, Danial; Suta, Márton; DE--Fogorvostudományi Kar; Bakó, József; Csermák, Sára; Debreceni Egyetem::Fogorvostudományi Kar::Bioanyagtani és Fogpótlástani Nem Önálló Tanszék
    Additive manufacturing (AM), also identified as 3-dimensional printing or rapid prototyping, is growing in popularity as the demand for greater-performance materials with progressive enhancement and increased geometrical complexities grows. Currently, most of the AM technologies have acceptable accuracy for dental applications and the reproducibility is high but the main disadvantages come with the compatible materials (most of the printers in this field are only good in case ofa limited number of materials), the time it takes to print, price of printer and services, and the extent of post-processing, Nonetheless, this approach has a great potential for development, and the future is bright not only in dentistry but in other aspects of life.

    Preparation and comparison of PEG-DMA based 3D printable hydrogels
    Nguyen, Quang Bach; Bakó, József; Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Szalóki, Melinda; Suta, Márton; Fogorvostudományi Kar
    The use of polyethylene glycol dimethacrylate (PEG-DMA) is extensive in tissue engineering due to its mechanical properties, lack of immunogenicity, recognized cytocompatibility, and ease of synthesis. In our study, PEG-DMA of 550 and 750 Da number average molecular weight polymer-based 3D printable solutions were prepared in a double photo-initiator system including riboflavin (Rb)/triethanolamine (TEA) and water-soluble diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (wsTPO). The 3D printable ink solutions and their consecutive hydrogels were investigated by rheological parameters, compressive and tensile mechanical properties, water swelling, contact angle measurement, and FTIR analysis. The results demonstrated that both PEG-DMA (Mn: 550 and 750) hydrogel systems were successfully printed using Rb/TEA and wsTPO photo-initiator system with an SLA 3D printer, making it an important form of hydrophilic polymer for biomedical applications, as well as in the field of dentistry such as surface modification, bioconjugation, drug administration, tissue engineering, and periodontal regenerative surgery. These properties of the 3D-printed hydrogels make these promising candidates for these applications in the near future.

    Preparation and investigation of BTCP reinforced hydrogel based composites
    Enteshari, Sepehr; Bakó, József; Fogorvostudományi Kar::Bioanyagtani és Fogpótlástani Nem Önálló Tanszék; DE--Fogorvostudományi Kar
    Beta Tri-Calcium Phosphate (BTCP) is a widely used material in the biomedical field. The 3D printability of hydrogel polymeric networks made of polyethylene glycol dimethacrylate (PEG-DMA) reinforced with the addition of BTCP filler was investigated. PEG-DMA was selected as the matrix component of the composite due to its cytocompatibility and absence of immunogenicity. In this research the BTCP contents were 2%, 5%, and 10% (w/w). PEG-DMA of 550 Dalton (Da) molecular weight was the hydrogel base. The three sets of samples all proved to be printable using the commercially available stereolithography type Form2 3D printer. The polymerization reaction chemically was confirmed to have taken place through FTIR testing.

    SLA-type 3D printed hydrogels for drug delivery
    Liu, Xinyi; Bakó, József; Fogorvostudományi Kar::Bioanyagtani és Fogpótlástani Nem Önálló Tanszék; DE--Fogorvostudományi Kar
    Alternative manufacturing techniques, such as 3D printing, have revolutionized medicine. The application of SLA-printed polyethylene glycol dimethacrylate (PEGDMA) hydrogels shows the potential to go beyond traditional “one-size-fits-all” drug designs, advancing personalized medicine through tailored drug delivery systems. This study proves that SLA-printed PEGDMA hydrogels are adaptable and effective for the creation of drug delivery systems. This distinct mechanical, swelling and drug-releasing behavior indicate their potential for personalized applications in different biomedical fields e.g. tissue engineering and wound healing.

    The Application Possibilities of 3D printed Hydrogels in Tissue Engineering
    Kaur, Bavleen; Bakó, József; Debreceni Egyetem::Fogorvostudományi Kar; DE--Fogorvostudományi Kar; Szalóki, Melinda; Suta, Márton; Debreceni Egyetem::Fogorvostudományi Kar
    This thesis discusses 3D printing in the field of regenerative medicine, with the greatest emphasis on its application within dentistry and maxillofacial surgery. Tissue engineering by 3D printing based on the use of human stem cells has shown a promising expansion for the restoration of dental and oro-facial tissues. The practice of using stem cells in regenerative dentistry provides a large amplitude of possible applications compared to synthetic tissues. Hydrogels – the printable bioink has proven to be a favourable material for the printing of live and functional tissues.
