“…At the same time, the dimensional accuracy of 3D printed prosthetic restorations depends on diverse factors, such as the position and angle of the restoration on the printing platform, the amount of supportive material, the laser speed, the material’s shrinkage rate, the post-processing procedures, and the type of design software. In addition to the above, the selection of interim restorations—with regard to their manufacturing process and materials—should be individualized considering the following factors: chewing forces, chewing pattern, parafunctions, length of edentulous spans, the age of edentulism, and the type of prosthetic restoration (supported by natural teeth or by dental implants) [ 58 , 59 , 60 ].…”

The purpose of this study was to analyze the oxidative stress level and inflammatory status of saliva in the presence of certain materials used for obtaining interim prosthetic restorations. Four types of interim resin materials were investigated: a pressure/heat-cured acrylic resin (Superpont C+B, SpofaDental a.s Czech Republic, /KaVo Kerr Group), a milled resin (Telio CAD polymethyl methacrylate, Ivoclar Vivadent AG, Liechtenstein), a 3D printed resin (NextDent C&B MFH, NextDent by 3D Systems, the Netherlands), and a pressure/heat-cured micro-filled indirect composite resin (SR Chromasit, Ivoclar Vivadent AG, Liechtenstein). The disk-shaped resin samples (30 mm diameter, 2 mm high) were obtained in line with the producers’ recommendations. The resulting resin specimens were incubated with saliva samples collected from twenty healthy volunteers. In order to analyze the antioxidant activity of the tested materials, certain salivary parameters were evaluated before and after incubation: uric acid, gamma glutamyl transferase (GGT), oxidative stress responsive kinase-1 (OXSR-1), and total antioxidant capacity (TAC); the salivary levels of tumor necrosis factor (TNFα) and interleukin-6 (IL-6) (inflammatory markers) were measured as well. The obtained results are overall favorable, showing that the tested materials did not cause significant changes in the salivary oxidative stress level and did not influence the inflammatory salivary status.

Medical 3D printing is emerging as a clinically relevant imaging tool in Directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. 3D printer technology is one of the innovations brought by the industrial age. It has been in our lives for many years. This miracle manufacturing method has been frequently preferred for medical applications in recent years. The main aim of this project is to minimise the time and cost for the design and manufacturing of the prosthesis. Getting the DICOM file from the MRI or CT scan which gives the body part dimensions (or) views of the body part in different directions . AUTODESK MESHMIXER and 3D SLICER software’s are used to extract and design the 3D prosthetic body part in this project, flexible Biomaterial is gone to be used for the flexibility in the respiration process. There are a lot uses of 3D printing technology in surgery, pharmaceutical industry, disease modelling, development of customized implants and prostheses, organ printing, vet medicine and tissue engineering applications have been explained and this new method compared with traditional methods that used in the biomedical field. In addition, this study includes future opportunities that are expected to become widespread and developed in the future. Keywords: 3D Printing, DICOM File, AUTODESK MESHMIXER, 3D Slicer.

“…Instead, photocurable resins at the liquid state are used. Stereolithography (SLA) is a vat polymerization technique in which the photocrosslinking of each layer is achieved by indirect exposure to an ultraviolet (UV) light laser beam [ 63 ]. Figure 16 shows a representation of SLA equipment.…”

Electroactive Polymers Obtained by Conventional and Non-Conventional Technologies

Electroactive polymers (EAPs), materials that present size/shape alteration in response to an electrical stimulus, are currently being explored regarding advanced smart devices, namely robotics, valves, soft actuators, artificial muscles, and electromechanical sensors. They are generally prepared through conventional techniques (e.g., solvent casting and free-radical polymerization). However, non-conventional processes such as those included in additive manufacturing (AM) are emerging as a novel approach to tune and enhance the electromechanical properties of EAPs to expand the scope of areas for this class of electro-responsive material. This review aims to summarize the published work (from the last five years) in developing EAPs either by conventional or non-conventional polymer processing approaches. The technology behind each processing technique is discussed as well as the main mechanism behind the electromechanical response. The most common polymer-based materials used in the design of current EAPs are reviewed. Therefore, the main conclusions and future trends regarding EAPs obtained by conventional and non-conventional technologies are also given.
