“…Furthermore, the ALP activity of rBMSCs on M 2 S-HA scaffolds was much higher than that on M 2 S scaffolds. It indicated that HA coating on M 2 S scaffolds could improve the bioactivity of scaffolds and promote the early osteogenic differentiation of rBMSCs [33].…”

Bone engineering scaffolds with antibacterial activity satisfy the repair of bacterial infected bone defects, which is an expected issue in clinical. In this work, 3D-printed polymer-derived forsterite scaffolds were proposed to be deposited with hydroxyapatite (HA) coating via a hydrothermal treatment, achieving the functions of photothermal-induced antibacterial ability and bioactivity. The results showed that polymer-derived forsterite scaffolds possessed the photothermal antibacterial ability to inhibit Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) in vitro, owing to the photothermal effect of free carbon embedded in the scaffolds. The morphology of HA coating on forsterite scaffolds could be controlled through changing the hydrothermal temperature and the pH value of the reaction solution during hydrothermal treatment. Furthermore, HA coating did not influence the mechanical strength and photothermal effect of the scaffolds, but facilitated the proliferation and osteogenic differentiation of rat bone mesenchymal stem cells (rBMSCs) on scaffolds. Hence, the HA-deposited forsterite scaffolds would be greatly promising for repairing bacterial infected bone defects.

The occlusal splint is a common medical device that is used to treat temporomandibular disorders. However, the current commercial occlusal splints still have several disadvantages in terms of flexibility, abrasion resistance, and occlusal inspection. In this work, ZnS:Mn 2+ /polydimethylsiloxane composite elastomers were prepared, and the mechanical and biological properties were investigated to evaluate their potential as occlusal splint materials. The results suggest that compared to the commercial occlusal splint material, ZnS:Mn 2+ /polydimethylsiloxane exhibits desirable flexibility, improved wear resistance, and excellent biocompatibility and antibacterial properties. In addition, the elastomer shows intense and stable mechanoluminescence under oral conditions with a linear relationship to the applied load. This further provides a visualized approach for the convenient and realtime detection of occlusal high points. Based on the above results, a mechanoluminescent occlusal splint model was fabricated, which is promising to be applied in occlusal splint therapy applications.

“…By developing towards biomimetic design in dental materials, the expanded use of dental monomers comes into focus. In particular, several groups have challenged convention and moved towards composites with continuous and interconnected rigid and pliable constituents [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Additionally, known as polymer infiltrated ceramic networks (PICN), these materials must be preprocessed as CAD/CAM (computer aided design/computer aided manufacturing) blocks or discs.…”

(1) Objectives: This work examined properties of dental monomer formulations of an aromatic dimethacylate (BisGMA), aliphatic urethane dimethacrylate (UDMA), and triethylene glycol dimethacrylate (TEGDMA). The monomers were combined in different ratio formulations and heat-polymerized containing the initiator benzoyl peroxide (BPO) specifically for the purpose of infiltration into polymer-infiltrated composite structures. (2) Methods: The monomers were combined in different weight ratios and underwent rheological analysis (viscosity and temperature dependence), degree of conversion, and mechanical properties (elastic modulus, hardness, fracture toughness). (3) Results: Rheological properties showed Newtonian behavior for monomers with a large dependence on temperature. The addition of BPO allowed for gelation in the range of 72.0–75.9 °C. Degree of conversion was found between 74% and 87% DC, unaffected by an increase of TEGDMA (up to 70 wt%). Elastic modulus, hardness, and fracture toughness were inversely proportional to an increase in TEGDMA. Elastic modulus and hardness were found slightly increased for UDMA versus BisGMA formulations, while fracture toughness ranged between 0.26 and 0.93 MPa·m0.5 for UDMA- and 0.18 and 0.68 MPa·m0.5 for BisGMA-based formulations. (4) Significance: Heat-polymerization allows for greater range of monomer formulations based on viscosity and degree of conversion when selecting for infiltrated composite structures. Therefore, selection should be based on mechanical properties. The measured data for fracture toughness combined with the reduced viscosity at higher UDMA:TEGDMA ratios favor such formulations over BisGMA:TEGDMA mixtures.
