Abstract Objective Agglomeration is a common problem facing the preparation and application of nanomaterials, and whether nano-hydroxyapatite (nano HA) can modulate oral microecology left to be unclear. In this study,…
Highlights • The composite filaments were successfully developed via melt-blending technique. • AMP-PEEK filaments can serve as feedstock for 3D printing of patient-specific implants. • The bioactivity of the composites…
Highlights • The clinical procedure to adhesively lute ceramic restorations is complex, by which a simplified application procedure is desirable. • Silane-coupling monomers degrade in water; hydrolysis is avoided when…
Abstract Objectives Tetrahydrofurfuryl-methacrylate (THFM) and hydroxypropyl-methacrylate (HPM) were used to partially or fully replace HEMA in experimental RMGICs. The experimental materials were compared with home and commercial products in terms…
Abstract Objective Water sorption, high volumetric shrinkage, polymerization stress, and potential estrogenic effects triggered by leached compounds are some of the major concerns related to BisGMA-TEGDMA co-monomer systems used in…
Abstract Narrow-diameter implants (NDIs) traditionally have been associated to higher rates of failure in comparison with regular-diameter implants (RDIs) and wide-diameter implants (WDIs), since they generate a more unfavorable stress…
Abstract Objectives The purpose of the study was to compare the mvM stresses occurring in inlays, onlays and endocrowns made from different materials and their bonding with molars in a…
Highlights • An increased surface roughness of zirconia reduces cell spreading of osteoblasts. • An increased tetragonal phase ratio of zirconia increases cell viability of osteoblasts. • Wettability is increased…
Abstract Objective To investigate the impact of high-speed sintering, layer thickness and artificial aging in a chewing simulator on the fracture load (FL) and two-body wear (2BW) of 4Y-TZP crowns….
Graphical abstract Abstract Objective This investigation tested pre-shaded 3Y-TZP materials on optical, mechanical and structural properties and calculated correlations between these properties. Methods Seven A2-shaded 3Y-TZP zirconia materials were investigated…
Highlights • Pre-heating does not reduce polymerization stress of resin composite restorations. • Thio-urethane addition increases resin composite degree of conversion. • Thio-urethane addition reduces resin composite polymerization stress. Abstract…
Graphical abstract Highlights • AgNPs cross-linked within glass ionomer cement (GIC) matrices generated antibiofilm effects at the nanocomposite surface. • AgNP-containing GICs had higher compressive strengths and equivalent flexural strengths…
Abstract Objectives Dental plaque build-up on the cervical area adjacent to gingival margins is a trigger factor for secondary caries around restored root caries lesions. Dimethylaminohexadecyl methacrylate (DMAHDM) and amorphous…
Highlights • Transmitted irradiance is affected by surface reflection, attenuation and scattering. • A correction calculating true transmitted irradiance can be implemented. • The model can be applied for individual…
Highlights • The C-factor is the relative thickness of the fully constrained boundary layer. • The boundary-layer thickness is proportional to the specimen’s diameter only. • The optical test presented…
Highlights • Composites with up to 40 wt% of fluorapatite could be made using dual asymmetric centrifugal mixing. • At high filler loads, fluorapatite rods introduced additional toughening mechanisms. •…
Abstract Objective Due to past failures of orthopedic 3Y-TZP femoral implants linked to accelerated tetragonal-to-monoclinic phase transformation ( t → m ), the susceptibility to ‘low-temperature degradation’ or ‘ageing’ of…
Abstract Objectives This study aimed to investigate the collective influence of material properties and design parameters on the fracture behavior of monolithic dental crowns. Methods Three-dimensional (3D) models ( N…
Graphical abstract Highlights • Material-dependent biomineralization achieved in vitro . • Performance of gold standard acid-etched titanium confirmed in in vitro test system. • Biomineralization leads to functional integration of…
Abstract Objectives Previous studies have shown that the fracture toughness of ceramics can be determined from the fractal dimensions (D) of their fracture surfaces and that the surface should be…
