The study described a novel bone tissue scaffold fabricated by computer-aided, air pressure-aided deposition system to control the macro- and microstructure precisely. The porcine bone marrow stem cells (PBMSCs) seeded on either mPEG-PCL-mPEG (PCL) or mPEG-PCL-mPEG/hydroxyapatite (PCL/HA) composite scaffold were cultured under osteogenic medium to test the(More)
This study investigates the effect of implant neck design on primary stability and overload using 3D finite element analysis. Four commercial dental implants and mandibular segments are created. Various parameters including the osseointegration condition (non-osseointegration and full osseointegration), force direction (vertical and horizontal), and(More)
We have simulated photon migration with various sourcedetector separations based on a three-dimensional Monte Carlo code. Whole brain MRI structure images are introduced in the simulation, and the brain model is more accurate than in previous studies. The brain model consists of the scalp, skull, CSF layer, gray matter, and white matter. We demonstrate(More)
OBJECTIVE The purpose of this study was to evaluate the influence of Cu-GHK aids for the LED-PI on fibroblast proliferation and collagen production in vitro. BACKGROUND DATA Light-emitting diode photoirradiation (LED-PI) and copper-glycyl-L-histidyl-L-lysine complex (Cu-GHK) treatment may be useful in accelerating the rate of wound healing. Red LED(More)
The aims of this study were to examine the effect of implant neck design and cortical bone thickness using 3D finite element analysis and to analyse the stability of clinical evidence based on micromotion and principal stress. Four commercial dental implants for a type IV bone and maxillary segments were created. Various parameters were considered,(More)
Bone tissue engineering is an emerging approach to provide viable substitutes for bone regeneration. Poly(ethylene glycol) (PEG) is a good candidate of bone scaffold because of several advantages such as hydrophilicity, biocompatibility, and intrinsic resistance to protein adsorption and cell adhesion. However, its low compressive strength limits(More)
The purpose of this research is to develop a new Masked Photopolymerization Rapid Prototyping (MPRP) System using liquid crystal displayer (LCD) panel. The design concept of the MPRP system is to use a dynamical photo mask for the layer profile. The layer pattern of the dynamic mask, generated by a thin film transistor liquid crystal displayer (TFT LCD)(More)
An innovative rapid prototyping (RP) system using direct mask photo curing (DMPC) is proposed in this paper. The underlying principle of RP system is to fabricate a three-dimensional part layer by layer. The design concept of the DMPC RP system is to use a dynamical photo mask for the layer profile. The image of the dynamic mask, generated by a thin film(More)
This study proposes a new methodology for dental implant customization consisting of numerical geometric optimization and 3-dimensional printing fabrication of zirconia ceramic. In the numerical modeling, exogenous factors for implant shape include the thread pitch, thread depth, maximal diameter of implant neck, and body size. Endogenous factors are bone(More)
