Summary: This study successfully prepared borate glasses doped with silver, which showed improved bioactivity and excellent antibacterial properties. The addition of silver enhanced the alkalinity of the glasses in simulated body fluid and led to the formation of hydroxyapatite and fluorapatite phases. Antibacterial tests demonstrated the efficiency of silver-doped borate glasses against both gram-negative and gram-positive bacteria.

Summary: This study investigates the effects of ZrO2 addition on the bioactivity and mechanical properties of a multicomponent bioactive glass-ceramic. The results show that ZrO2 reduces the crystallisation ability and bioactivity of the glass-ceramic, but the addition of YSZ particles leads to improved mechanical strength and bioactivity. These findings suggest a promising method for producing bioactive glass-ceramics for load-bearing clinical applications.

Summary: Silicate bioglass is essential in bone engineering for its bioactivity and osteogenic effects. The study synthesized hydroxyapatite-like bioactive glass based on the xSiO2-CaO-P2O5 system and investigated its structural evolution, apatite-forming ability, and cytotoxicity. Higher heat treatment temperature and lower SiO2 content increase crystallinity tendency and sample compactness, with 30Si sample showing remarkable mesoporous structures and high specific surface area, demonstrating excellent hydroxyapatite formation and no inhibitory effect on hPDLCs.

Summary: A postgrafting strategy mediated by polydopamine (PDA) coating is proposed to incorporate different metal elements into mesoporous silicate bioactive glass nanoparticles (MBG NPs) while maintaining their stability. However, the PDA coating reduces the ion-binding free energy of MBG NPs for calcium and phosphate ions, resulting in minimal deposition of calcium phosphate clusters on the PDA@MBG NP surface after immersion in simulated body fluid for 7 days, indicating a lack of hydroxyapatite mineralization.

Summary: Bioactive phosphate glasses doped with Zn2+ demonstrated excellent bioactivity and bone regeneration potential in simulated body fluid. ZnO concentration and immersion time were found to impact the formation of hydroxyapatite (HAP) layer on the sample surface, while controlled release of Zn2+ ions could monitor the degradation rate. In vitro cell studies showed favorable outcomes in terms of rMSC cell proliferation. Antibacterial activity against E. coli and S. aureus was confirmed, highlighting the enhanced biological and antibacterial properties of the samples due to ZnO doping.

Summary: Most bioactive molecules need to cross or be distributed into biological membranes, and natural products often have lipid modifications to facilitate molecule-membrane interactions. Lipidated natural products primarily contain saturated medium-chain lipids, and lipid conjugation can significantly modulate the permeability, cellular retention, subcellular localization, and bioactivity of small molecules.

Summary: The study evaluates the long-term impact of alveolar ridge preservation (ARP) on peri-implant health and its relationship with common risk indicators such as smoking and history of periodontitis. The findings suggest that peri-implant health can be maintained for at least 5 years in ARP(+) sites using deproteinized bovine bone mineral xenograft. Smoking is a major risk indicator for peri-implantitis, while the association between history of periodontitis and risk of peri-implantitis remains inconclusive.

Summary: In the past decade, additive manufacturing technologies, particularly electron beam melting (EBM), have revolutionized the production of biomedical implants. EBM offers faster build rates and a high vacuum environment, making it advantageous for materials susceptible to oxidation and nitrogen pick-up. EBM manufactured implants have shown great potential in skeletal reconstruction, with anatomical mimickry and macro-porous architecture. The personalized design and diverse clinical applications of EBM in skeletal repair and prosthetic rehabilitation are discussed in this review.

Summary: The success of metal implants in rehabilitation is due to osseointegration, the direct connection between living bone and the implant. Removal torque measurement can assess the extent of biomechanical anchorage between the implant and bone. Various pharmacological agents have been evaluated for their impact on osseointegration, with some substances showing positive effects on removal torque and others showing adverse effects. Factors such as bone quality play a role in the biomechanical anchorage of metal implants, and questions regarding drug metabolism, dosage, and treatment interruption remain unanswered.

Summary: This study investigates the interface between necrotic bone and bacteria in medication-related osteonecrosis of the jaw (MRONJ) using a multimodal and multiscale characterization approach.

Summary: The lacuno-canalicular space of apoptotic osteocytes in ageing bone becomes mineralised, forming hypermineralised osteocyte lacunae that indicate impaired bone function. The mineralised apoptotic debris in the lacuno-canalicular space consists of micrometre-sized nodules of magnesium-rich, carbonated apatite. Additionally, rhomboidal nodules of magnesium whitlockite have been observed in human alveolar bone exposed to the bisphosphonate alendronate. This study provides evidence of Mg-whitlockite formation in alveolar bone exposed to zoledronic acid.

Summary: This study investigates the differences in composition of acid phosphate, carbonate, hydroxyl, iron, and magnesium content between pigmented incisor enamel and unpigmented molar enamel of Sprague Dawley rats. The results reveal that iron-rich pigmented enamel has higher mineral crystallinity, higher levels of acid phosphate and hydroxyl, and no presence of iron oxides or oxy(hydroxides). These findings provide new insights into enamel biomineralization and the functional differences of ameloblasts between incisors and molars in rodents.

Summary: In recent years, there has been an evolution of imaging technologies for visualising cells and investigating their interactions with other cells, anatomical structures, and biomaterials. Resin cast etching (RCE) is a simple technique for observing the osteocyte lacuno-canalicular network in bone using scanning electron microscopy. RCE can be used to investigate various quantitative and qualitative parameters, including size and density of osteocytes, arrangement of osteocytes and canaliculi, and communication between osteocytes and implant surfaces. It has applications in studying bone-related diseases and evaluating the osseointegration potential of different materials.
