Summary: This study presents a practical and effective strategy to improve osseointegration in patients with osteoporosis. By coating titanium implants with polydopamine followed by strontium modification, the bi-functional implants promote bone regeneration and immune regulation. The results show good biocompatibility, sustained release of strontium ions, and stable osseointegration between bone tissues and implants.

Summary: This literature review investigated the characteristics and management of bisphosphonate-associated bilateral atypical femoral fractures (AFFs). A comprehensive analysis of 43 patients with bilateral AFFs revealed that 67% had prodromal symptoms, 49% occurred simultaneously, and 51% occurred sequentially. X-ray was used for initial diagnosis, with 53% having complete fractures. Surgical treatment was performed for all patients, except for those with incomplete fractures who received either surgical or medical treatments. Teriparatide was the most commonly used medication after bisphosphonate discontinuation.

Summary: This study aimed to compare the efficacy of alendronate and teriparatide in the treatment of glucocorticoid-induced osteoporosis. The study found that compared to alendronate, teriparatide could reduce the rate of new vertebral fractures and increase the bone mineral density of the lumbar spine, femoral neck, and total hip. There was no significant difference in the incidence of non-vertebral fractures and adverse events between the two groups.

Summary: This study aimed to investigate the risk of major osteoporotic fractures in diabetes patients initiated with alendronate and denosumab. Results showed that the risk of incident major osteoporotic fractures among subjects with diabetes was similar between those initially treated with alendronate and denosumab, suggesting both treatments are equally effective in preventing osteoporotic fractures in subjects with diabetes.

Summary: The study investigated the short-term effects of postoperative systemic alendronate on osseointegration using a mouse implant model. Results showed that alendronate treatment enhanced osseointegration, increasing bone mass and maximum pullout load, while decreasing peri-implant osteoclasts. This data supports the postoperative clinical use of bisphosphonates, especially in patients with high risks of aseptic loosening.

Summary: The combination of alendronate and metformin has a positive effect on improving glucose metabolism and bone metabolism in diabetic mice. Alendronate significantly increases serum glucagon-like peptide-1 levels, while metformin improves bone microstructure. The combined use of alendronate and metformin shows better anti-diabetes and anti-osteoporotic effects compared to diabetic mice.

Summary: Patients with osteoporosis often experience surgical failure after oral implantation due to low bone density and poor bone healing ability. This study investigated the effect of new-type implants on osseointegration in osteoporotic rats. The results showed that the implants induced more new bone formation and tighter osseointegration, suggesting a potential new strategy for implant surgery in osteoporosis patients.

Summary: The study aimed to evaluate the effects of vitamin D alone or in combination with teriparatide on peri-implant bone tissue in orchiectomized rats. Through an in vivo study, it was found that treatment with vitamin D and teriparatide together can increase the volume of bone tissue around the implant and improve bone quality. However, given the increasing population with bone metabolism disorders seeking dental implant rehabilitation treatment, the verification of medications that promote an increase in bone density is essential.

Summary: Type 1 (T1DM) and type 2 (T2DM) diabetes mellitus affect glucose metabolism and cause bone damage through various mechanisms, including the impact on osteoblasts. This study examined the osteoblast differentiation of mesenchymal stem cells (MSCs) from rats with T1DM or T2DM and the effects of removing hyperglycemia on the osteogenic potential of these cells. The results showed that both T1DM and T2DM inhibited the osteoblast differentiation of MSCs cultured in hyperglycemic media, with T1DM having a more significant effect. Restoring normoglycemic conditions partially recovered the osteogenic potential of MSCs from rats with T1DM but not with T2DM. These findings highlight the need for targeted therapies for T1DM- or T2DM-induced bone loss, as both conditions disrupt osteoblast differentiation at different levels and likely through different mechanisms.

Summary: This study evaluated the bone repair in critical defects using a polydioxanone membrane (Plenum((R)) Guide) and a collagen-based membrane (Bio-Gide((R))) in rats. The results showed that the Plenum((R)) Guide group had better bone regeneration and gene expression, but there was no significant difference between the two groups in histometric and micro-CT analyses. Therefore, the absorbable polydioxanone membrane is an effective guided bone regeneration membrane.

Summary: After tooth loss, bone remodeling can cause significant decreases in bone height and thickness, which can compromise the success of dental implants. Leukocyte-platelet-rich fibrin (L-PRF) has shown potential in promoting tissue regeneration and several protocols have been proposed to improve its regenerative potential. In this study, different centrifugation protocols were evaluated for their effectiveness in bone healing in rat calvaria defects. The results showed that platelet aggregates, especially with horizontal centrifugation, improve bone neoformation and have more biological potential for bone healing.

Summary: The study aimed to investigate the efficacy of chlorhexidine in preventing ventilator-associated pneumonia (VAP). A systematic review and meta-analysis were conducted, and data were obtained from Pubmed, Cochrane Library, and EMBASE. Ten randomized clinical trials involving 1233 mechanically ventilated patients were included. Results showed that oral application of chlorhexidine reduced the incidence of VAP, but the evidence quality for mortality rates was very low.

Summary: This study compared senile rats (SENIL) with young ovariectomized rats (OXV) to select a critical animal model for assessing bone repair with implant installation. The results showed that the SENIL group had lower cell viability, more critical gene expression, lower alkaline phosphatase activity, and mineralization nodules. In vivo histometric and biomechanical analysis also indicated inferior bone condition in the SENIL group. Confocal microscopy revealed fragile bones in the SENIL group. Microtomography results were similar between the groups. These findings suggest that the senile model can provide a more critical bone condition for investigating biomaterial properties and topographic changes.

Summary: This study evaluated the effects of infrared laser (IRL) on bone repair in rats with ovariectomies. The results showed that IRL increased bone turnover and promoted new bone formation, especially in rats with low bone mineral density. These findings suggest that IRL could be used intraoperatively to optimize bone repair.
