Al-Azhar Journal of Dentistry
Purpose: This study was conducted to investigate the influence of cubic and diamond unit cell types, with 80% porosity on mechanical behavior of titanium alloy (Ti6Al4V) scaffolds and cell attachment. Material and Methods: The titanium scaffold was fabricated by Selective Laser Melting (SLM), and then surface modification was done by biomimetic coating. Morphological characterization of the samples was performed through SEM, EDX and XRD system before and after modification. The samples were cultured for cell attachment and then subjected to compressive loading to assess the mechanical properties of the scaffolds. Results: The morphological results demonstrated that the geometric dimensions of …

Purpose: The present study aimed to synthesize and characterize photocurable resin with lower cost to be used in DLP 3D printing to fabricate clear dental appliances like surgical guides and aligners. Materials and Methods: Mixture of acrylates of 1,10 decandiol diacrylate, pentaerythritol tetracrylate and isobornyl acrylare were mixed together and dissolve the photo initiator phenyl bis (2,4,6 trimethylbenzoyl) phosphine oxide and optical absorber 2,5-bis (tert-butyl-benzoxzzol-2-yl) thiophene by proper mixing for 30 mins at room temperature. Then experimental resin specimens were fabricated by DLP 3D printer 12 specimens were subjected to post curing for 15 mins and another 12 specimens were …
