In silico assessment of biocompatibility and toxicity: molecular docking and dynamics simulation of PMMA-based dental materials for interim prosthetic restorations

Journal of Materials Science Materials in Medicine, Год журнала: 2024, Номер 35(1)

Опубликована: Июнь 4, 2024

Abstract Aim: This study aimed to comprehensively assess the biocompatibility and toxicity profiles of poly(methyl methacrylate) (PMMA) its monomeric unit, methyl methacrylate (MMA), crucial components in dental materials for interim prosthetic restorations. Methodology: Molecular docking was employed predict binding affinities, energetics, steric features MMA PMMA with selected receptors involved bone metabolism tissue development, including RANKL, Fibronectin, BMP9, NOTCH2, other related receptors. The HADDOCK standalone version utilized calculations, employing a Lamarckian genetic algorithm explore conformational space ligand-receptor interactions. Furthermore, molecular dynamics (MD) simulations over 100 nanoseconds were conducted using GROMACS package evaluate dynamic actions structural stability. LigandScout pharmacophore modeling, which employs shape-based screening approach identify potential ligand sites on protein targets. Results: studies elucidated promising interactions between key biomolecular targets relevant applications. MD simulation results provided strong evidence supporting stability complexes time. Pharmacophore modeling highlighted significance carbonyl hydroxyl groups as pharmacophoric features, indicating compounds favorable profiles. Conclusion: underscores applications, emphasizing stability, interactions, safety considerations. These findings lay foundation future advancements biomaterials, guiding design optimization enhanced biocompatibility. Future directions include experimental validation computational development PMMA-based improved clinical performance. Graphical

Mechanical Properties of Additive-Manufactured Composite-Based Resins for Permanent Indirect Restorations: A Scoping Review

Materials, Год журнала: 2024, Номер 17(16), С. 3951 - 3951

Опубликована: Авг. 8, 2024

The introduction of 3D printing technology in dentistry has opened new treatment options. ongoing development different materials for these purposes recently enabled the production definitive indirect restorations via printing. To identify relevant data, a systematic search was conducted three databases, namely PubMed, Scopus, and Web Science. Additionally, manual using individual terms performed. Only English, peer-reviewed articles that encompassed vitro or vivo research on mechanical properties 3D-printed composite were included, provided they met predefined inclusion exclusion criteria. After screening 1142 articles, 14 primary studies selected. included mainly utilized digital light processing (DLP) technology, less commonly stereolithography (SLA), once PolyJet technology. material various resins, such as VarseoSmile Crown Plus (VSC) Crowntec (CT), studied, including Vickers hardness, flexural strength, elastic modulus, compressive tensile fracture resistance, wear. aimed to compare behavior tested additive composites each other, conventional composites, subtractive-manufactured materials. This scoping review examined used restorations. aim provide comprehensive overview current knowledge this topic any gaps future research. findings suggest are not yet first option restorations, due their insufficient properties. Due limited evidence, more is needed area. Specifically, there need clinical trials long-term

The present study aimed to characterize the microstructure of a temporary 3D printing polymer-based composite material (Resilab Temp), evaluating its optical properties and mechanical behavior according different post-curing times. For analysis surface establishment best pattern, samples in bar format following ISO 4049 (25 × 10 3 mm) were designed CAD software (Rhinoceros 6.0), printed on W3D printer (Wilcos), light-cured Anycubic Photon for lengths time (no post-curing, 16 min, 32 60 min). structural characterization, analyses carried out using Fourier transform infrared spectroscopy (FT-IR) scanning electron microscopy (SEM). this was determined based flexural strength tests Knoop microhardness. Color translucency performed spectrophotometer (VITA Easy Shade Advanced 4.0), which then evaluated CIELab, gray, black, white backgrounds. All immediately after making repeated thermal aging over two thousand cycles (5-55 °C). results obtained statistically analyzed with significance level 5%. FT-IR showed about 46% degree conversion 37% center resin sample. higher groups polymerized min 1 h, while microhardness did not show statistical difference between groups. also differences According all study, material, post-polymerization h should be suggested improve performance 3D-printed devices.
