Fused deposition modeling (FDM) is a rapidly growing three-dimensional (3D) printing technology and has great potential in medicine. Polyether-ether-ketone (PEEK) biocompatible high-performance polymer, which suitable to be used as an orthopedic/dental implant material. However, the mechanical properties biocompatibility of FDM-printed PEEK its composites are still not clear. In this study, pure carbon fiber reinforced (CFR-PEEK) composite were successfully fabricated by FDM characterized...
Abstract Objective This in vitro study was conducted to assess the marginal adaptation and fracture resistance of computer aided design/computer manufacturer (CAD‐CAM) fabricated endocrowns restoring endodontically treated molars using different machinable blocks with thermomechanical loading protocols. Materials Methods Devitalized mandibular were prepared a standardized way divided into 4 groups ( n = 10) receive CAD/CAM four materials (Lithium disilicate ceramics, polymer infiltrated...
Cobalt-chromium (Co-Cr) alloy is a widely used base material for dental fixed prostheses. These restorations can be produced through casting technique, subtractive or additive manufacturing technologies. However, limited information available regarding the influence of techniques on properties Co-Cr since most studies different chemical compositions methods. This study compares mechanical properties, metal-ceramic bond strength, and microstructures specimens by casting, milling, selective...
Polyetheretherketone (PEEK) is a prime candidate to replace metallic implants and prostheses in orthopedic, spine cranio-maxillofacial surgeries. Fused-filament fabrication (FFF) an economical efficient three-dimensional (3D) printing method fabricate PEEK implants. However, studies pertaining the bioactivity of FFF 3D printed are still lacking. In this study, samples were fabricated modified with polishing grit-blasting (three alumina sizes: 50, 120, 250 µm) achieve varying levels surface...
The topical literature lacks any comparison between stereolithography (SLA) and direct light processing (DLP) printing methods with regard to the accuracy of complete denture base fabrication, thereby utilizing materials certified for this purpose. In order investigate aspect, 15 bases were printed SLA DLP using three build angles: 0°, 45° 90°. dentures digitalized a laboratory scanner (D2000, 3Shape) analyzed in analyzing software (Geomagic Control X, 3D systems). Differences datasets...
Polyetheretherketone (PEEK), a biomaterial with appropriate bone-like mechanical properties and excellent biocompatibility, is widely applied in cranio-maxillofacial dental applications. However, the lack of antibacterial effect an essential drawback PEEK material might lead to infection osseointegration issues. This study aims apply natural agent, totarol coating onto 3D printed surface find optimized concentration balanced cytocompatibility, osteogenesis, capability.
The utilization of intraoral scanning for manufacturing complete dentures (CD) has been reported recently. However, functional border molding still cannot be supported digitally. A proof-of-concept trial shows two possible pathways to overcome this limitation by integrating a relining procedure into the digital workflow CD manufacturing.Intraoral scans and additional facial were performed with various systems rehabilitation an edentulous male patient. obtained raw data was aligned used...
(1) Background: To date, no information on the polishability of milled and 3D-printed complete denture bases has been provided, which is relevant in terms plaque accumulation. (2) Methods: three groups (n = 30) were manufactured using cold-polymerization polymethilmethacrilate, milling (SM) 3D printing (AM). 10 specimens each group left untreated (reference). more pre-polished (intermediate polishing) final highgloss polished. An additional 20 printed coated with liquid resin (coated),...
The objective of this study was to determine the effect two plasma surface treatments on biologic responses PEEK medical implants manufactured by fused filament fabrication (FFF) 3D printing technology.This created standard samples using an FFF printer. After fabrication, half were polished simulate a smooth surface. Then, argon (Ar) or oxygen (O2) used modify bioactivity printed and samples. Scanning electron microscopy (SEM) profilometer microstructure roughness sample surfaces....
Abstract Titanium dental implants with sandblasted and/or acid-etched surfaces have shown clinical superiority in comparison to their smooth, machined counterparts, and are now state of the art. Sandblasting finished, sintered zirconia implants, however, will damage surface structure affect mechanical properties. To improve osseointegration without impairing original strength by crack initiation partial phase transformation from tetragonal monoclinic, roughening sandblasting before final...
Abstract Purpose The use of computer‐aided design/computer‐aided manufacturing (CAD/CAM) and additive in maxillofacial prosthetics has been widely acknowledged. Rapid prototyping can be considered for auricular prostheses. Therefore, so‐called prostheses replicas fabricated by digital means. objective this study was to identify a superior method fabricate prosthesis (APRs) within workflow. Materials Methods Auricles 23 healthy subjects (mean age 37.8 years) were measured vivo with respect an...
Abstract Background Advanced digital workflows in orthodontics and dentistry often require a combination of different software solutions to create patient appliances, which may be complex time-consuming process. The main objective this technical note is discuss treatment craniofacial anomalies using technologies. We present fully digital, linear workflow for manufacturing palatal plates infants with based on intraoral scanning. Switching scanning infant care advantageous as taking...
Abstract Background Orthodontic treatment of newborns and infants with Robin-Sequence using the Tübingen Palatal Plate (TPP) is a complex procedure that could benefit from simplification through digitalization. The design velar extension (spur) palatal base determines success treatment. Therefore, prototype must be produced inserted under endoscopic supervision in order to determine appropriate shape, length position spur. This technical note demonstrates fully digital workflow for...
