Summary: The experiment aimed to evaluate the biological behavior of two xenogenic scaffolds in alcohol-induced rats with tibia defects. Results showed that both biomaterials promoted bone formation, with Bio-Oss((R)) being superior to OrthoGen((R)), while alcohol intake had a negative impact on the healing process and new bone formation.

Summary: The study found that the addition of BM and the type of implant surface did not have a significant impact on osseointegration in areas grafted with sintered deproteinized bovine bone at high temperatures. There were no differences observed in the quantity of mineralized tissues around the implants or the bone-implant contact between the different groups assessed.

Summary: Comparing different bone grafts for treating critical-size defects, autogenous bone showed the best results and there was no significant difference in new bone formation among the experimental groups. The use of an e-PTFE membrane did not significantly affect new bone formation.

Summary: This study compared the osseointegration and osteogenesis of particulate deproteinized porcine bone mineral (PDPBM) and collagenated block deproteinized porcine bone mineral (BDPBM) in single-stage maxillary sinus augmentation with the lateral window. Results showed that BDPBM required less time for bone substitute insertion and provided similar bone-to-implant contact compared to PDPBM. BDPBM also showed better osteogenesis and osseointegration in the augmented sinus area. Therefore, BDPBM may save time and provide comparable bone formation and integration.

Summary: This study compares the use of synthetic hydroxyapatite and xenograft for bone defects in rat calvaria, and found a significant enhancement in new bone matrix formation in groups using biomaterials compared to the control group. However, the addition of bone marrow mononuclear fraction did not further enhance the potential of hydroxyapatite-based biomaterials to induce bone matrix formation.

Summary: The study compared the bioreactivity characteristics of titanium implants pre-treated with a novel bone bioactive liquid (BBL) and commercially available BLT-SLA active in an animal model. Results showed that implants pre-treated with BBL exhibited improved osseointegration properties and reduced crestal bone loss compared to the control group, suggesting enhanced healing and tissue regeneration at the implant site.

Summary: The study investigated the immunohistochemical characteristics of a highly porous synthetic bone substitute and a cross-linked collagen membrane for guided bone regeneration. Results showed that combining biphasic calcium phosphate with a crosslinked collagen membrane resulted in extended osteogenic potential compared to deproteinized bovine bone mineral and a native collagen membrane. There was no significant difference in the angiogenic potential between the different groups.

Summary: The aim of this study was to investigate the effect of synthetic bone substitutes in combination with deproteinized bovine bone mineral on bone formation. The results showed that the combination of alpha-TCP and DBBM resulted in similar levels of new bone formation compared to the negative control. Micro-CT analysis indicated resorption of the combined materials, but without any change in volume.

Summary: This study assessed bone height between novel tapered implants at different inter-implant thread peak (TP) distances, and the impact of TP distance from outer buccal bone (BB) on marginal bone levels (MBL). The results showed that inter-implant bone height between adjacent implants can be maintained even at an inter-implant TP distance as low as 1 mm, but a minimum TP to outer BB distance of 0.75 mm is required for predictable maintenance of MBL.

Summary: This review provides a comprehensive overview of the applications of stem cells and biomaterials in bone tissue regeneration. The interaction between bone biology, stem cells, and biomaterials is briefly explained. The behavior and mechanism of biomaterials influencing stem cells during bone tissue regeneration are emphasized. Lastly, the future outlook for overcoming the current challenges in designing biomaterials/stem cell materials for bone tissue engineering is discussed.

Summary: This article explores the recent advances and future prospects for diamond-based coatings of conventional osteo-implant materials, emphasizing the ability of these coatings to improve integration with existing bone, enhance implant mechanical properties, facilitate surface chemical functionalization, and provide anti-microbial properties. In addition, diamond coatings may have an osteo-inductive effect, improving implant integration through stem cell recruitment and bone regeneration. Current research is highlighted to support further improvement in implant integration through an osseoinductive effect from diamond composite materials.

Summary: Understanding the optimal conditions for bone healing is crucial for addressing non-unions and large bone defects. In this study, a tissue engineered complex combining bioactive factors, regenerative progenitor cells, and biomaterials was tested in vitro and in vivo. The results showed enhanced gene expression and mineral deposition in the biomaterials in vitro, but limited ectopic bone formation and no enhanced bone healing in vivo. The study highlights the discrepancy between in vitro and in vivo outcomes and calls for more complex in vitro models for translational studies.

Summary: This study investigated the stability of orthodontic mini-implants under immediate orthodontic functional load, with or without splinting, and examined the histomorphometric parameters of the adjacent bone tissue in an in vivo experimental model. Mini-implants were placed in rabbits' proximal tibia and loaded with a 150g force. The study found that splinting reduced the tipping of mini-implants to levels similar to unloaded implants, and immediate loading increased bone formation at the peri-implant region. This study highlights the importance of splinting in minimizing displacement while promoting bone formation in orthodontic treatment with mini-implants.

Summary: The study reveals that in mid-adult life, appetite disinhibition is associated with higher BMI and accounts for 34% of genetically-linked BMI differences. Hunger is also linked to higher BMI and slightly steeper weight gain, but does not attenuate the impact of disinhibition.

Summary: This study compared the subgingival microbiota of patients with aggressive and chronic periodontitis to healthy individuals and explored their associations with host genetic variants. The results showed limited microbial differences between AgP and CP, challenging the notion that periodontitis is associated with increased subgingival microbial diversity compared with periodontal health. Different microbial abundances were observed between periodontitis patients and healthy individuals, but no associations between genetic variants and microbial findings were detected.

Summary: Researchers studied cytokines as predictive biomarkers of peri-implantitis and characterized the soft and hard tissues in patients with the disease. The presence of mast cells and osteocytes was observed in all samples, and the expression of APRIL and BAFF was associated with bone resorption in peri-implantitis.

Summary: This study investigated the effect of in vitro biofilm decontamination on the surface characteristics, wettability, chemistry, and biocompatibility of dental implants. The results showed that different decontamination methods altered the surface chemistry and morphology of the implants. The type of decontamination and implant surface had a significant impact on biocompatibility, with chemical agents and micro-rough surfaces showing higher cytotoxicity. Smooth surfaces and photofunctionalization of the TiO2 layer had a beneficial effect on biocompatibility after decontamination.

Summary: This study investigated the concentration levels of various biomarkers in the peri-implant crevicular fluid (PICF) of patients with peri-implant mucositis, peri-implantitis, and healthy implants. The results showed that the concentrations of CCL-20/MIP-3 alpha, BAFF/BLyS, IL-23, RANKL, and Osteoprotegerin were higher in the diseased groups compared to the healthy group. IL-23 and RANKL may play a role in the pathogenesis of peri-implantitis, and further research is needed on BAFF/BLyS for early diagnosis.

Summary: This study developed a novel in vitro microcosm biofilm model for peri-implantitis, a disease influenced by dysbiotic microbial communities. The model successfully simulated the progression from peri-implant mucositis to peri-implantitis and identified the bacterial shifts associated with the disease. This research provides valuable insights into the development of peri-implantitis and its treatment.
