Retention and fatigue performance of modified polyetheretherketone clasps for removable prosthesis
CONCLUSIONS: Proportions of PEEK clasp arm engaging the undercut positively influenced the retentive force and the fatigue resistance of PEEK clasps was superior than CoCr clasps. It is a feasible method to improve the retention of PEEK clasps by increasing the proportion of clasp arm engaging the undercut. Clinical trials are needed to further verify this innovation.PMID:38598917 | DOI:10.1016/j.jmbbm.2024.106539 (Source: Journal of the Mechanical Behavior of Biomedical Materials)

Development of ZTA (80% Al 2 O 3 /20% ZrO 2 ) pre-sintered blocks for milling in CAD/CAM systems
J Mech Behav Biomed Mater. 2024 Apr 1;154:106533. doi: 10.1016/j.jmbbm.2024.106533. Online ahead of print.ABSTRACTThe present work aims to develop a production method of pre-sintered zirconia-toughened-alumina (ZTA) composite blocks for machining in a computer-aided design and computer-aided manufacturing (CAD-CAM) system. The ZTA composite comprised of 80% Al2O3 and 20% ZrO2 was synthesized, uniaxially and isostatically pressed to generate machinable CAD-CAM blocks. Fourteen green-body blocks were prepared and pre-sintered at 1000 °C. After cooling and holder gluing, a stereolithography (STL) file was designed and upload...

Data analysis of the influence of microstructure, composition, and loading conditions on stress corrosion cracking behavior of Mg alloys
J Mech Behav Biomed Mater. 2024 Mar 26;154:106510. doi: 10.1016/j.jmbbm.2024.106510. Online ahead of print.ABSTRACTStress corrosion cracking (SCC) can be a crucial problem in applying rare earth (RE) Magnesium alloys in environments where mechanical loads and electrochemical driven degradation processes interact. It has been proven already that the SCC behavior is associated with microstructural features, compositions, loading conditions, and corrosive media, especially in-vivo. However, it is still unclear when and how mechanisms acting on multiple scales and respective system descriptors predictable contribute to SCC for...

Evaluation of a vibration modeling technique for the in-vitro measurement of dental implant stability
This study's purpose was to determine whether changes in density, bonding, and drilling technique affect the measured vibration of a dental implant, and whether they can be quantified as a change in the estimated BII stiffness. Stability was also measured using RFA, insertion torque (IT) and the pullout test. Bone-level tapered implants (4.1 mm diameter, 10 mm length) were inserted in polyurethane foam as an artificial bone substitute. Samples were prepared using different bone densities (20, 30, 40 PCF), drilling sequences, and superglue to simulate a bonded implant. Measurements were compared across groups at a significa...

Exploiting light-based 3D-printing for the fabrication of mechanically enhanced, patient-specific aortic grafts
This study reports on the development and characterisation of an alternative vascular graft material. An alginate:PEGDA (AL:PE) interpenetrating polymer network (IPN) hydrogel has been produced with uniaxial tensile tests revealing similar strength and stiffness (0.39 ± 0.05 MPa and 1.61 ± 0.19 MPa, respectively) to the human aorta. Moreover, AL:PE tubular conduits of similar geometrical dimensions to segments of the aorta were produced, either via conventional moulding methods or stereolithography (SLA) 3D-printing. While both fabrication methods successfully demonstrated AL:PE hydrogel production, SLA 3D-printing was m...

Region partitioning of articular cartilage with streaming-potential-based parameters and indentation maps
J Mech Behav Biomed Mater. 2024 Mar 31;154:106534. doi: 10.1016/j.jmbbm.2024.106534. Online ahead of print.ABSTRACTArticular cartilage exhibits site-specific tissue inhomogeneity, for which the tissue properties may continuously vary across the articular surface. To facilitate practical applications such as studying site-specific cartilage degeneration, the inhomogeneity may be approximated with several distinct region-wise variations, with one set of tissue properties for one region. A clustering method was previously developed to partition such regions using cartilage indentation-relaxation and thickness mapping instead ...

Use of marine occurrent extracts to enhance the stability of dentin extracellular matrix
J Mech Behav Biomed Mater. 2024 Mar 14;154:106498. doi: 10.1016/j.jmbbm.2024.106498. Online ahead of print.ABSTRACTChitosan (CS) and phloroglucinol (PhG), two extracts abundantly found in marine life, were investigated for their ability to biomodify demineralized dentin by enhancing collagen crosslinks and improving dentin extracellular matrix (ECM) mechanical and biochemical stability. Dentin obtained from non-carious extracted human molars were demineralized with phosphoric acid. Baseline Fourier-transform infrared (FTIR) spectra, apparent flexural elastic modulus (AE) and dry mass (DM) of each specimen were independentl...

Trueness, physical properties, and surface characteristics of additive-manufactured zirconia crown
CONCLUSION: The AM zirconia crowns showed bubbles and a rougher surface compared to the SM crowns. All groups exhibited typical zirconia traits and trueness levels within clinically acceptable limits, suggesting that current zirconia AM techniques could be suitable for dental applications.PMID:38579394 | DOI:10.1016/j.jmbbm.2024.106536 (Source: Journal of the Mechanical Behavior of Biomedical Materials)

Size effect in polymeric lattice materials with size-dependent Poisson's ratio caused by Cosserat elasticity
J Mech Behav Biomed Mater. 2024 Apr 3;154:106532. doi: 10.1016/j.jmbbm.2024.106532. Online ahead of print.ABSTRACTPolymeric lattice materials with micro/nano-structures are attractive for applications in a wide range of bioengineering systems. Resent experimental results show that elastic constitutive law of polymer materials is in line with the Cosserat elasticity. In this work, a Cosserat continuum spectral element method is employed to explore the size-dependent mechanical performance of polymer polymeric lattice with horseshoe microstructures, efficiently. The mechanical performance predicted by the proposed method agr...
