Diabetic Serum Inhibits Osteoblast Adhesion to Titanium Surface Through Advanced Glycation End Products: An In Vitro Study.
CONCLUSION: Osteoblast adhesion on the titanium surface was greatly reduced by the exposure of serum derived from diabetic rats or humans. Recovery of osteoblast aggregates by aminoguanidine treatment suggests that AGEs played a role in this negative effect. The correlating presence of AGEs from the fractionated sera of diabetic rats or humans and impaired osteoblast adhesion on the titanium surface further supports this role.

Immediate Dental Implant Stabilization in a Canine Model Using a Novel Mineral-Organic Adhesive: 4-Month Results.
CONCLUSION: The mineral-organic adhesive provides immediate (osseointegration-like) and continued implant stabilization over 4 months in sites lacking primary stability. Experimental sites demonstrated maintenance of crestal bone levels adjacent to the mineral-organic adhesive and soft tissue exclusion without the use of membranes in this canine model. These results demonstrate that this novel mineral-organic adhesive can enable implant osseointegration in a site where insufficient native bone exists to allow immediate implant placement.

Is History of Periodontal Disease Still a Negative Risk Indicator for Peri-implant Health Under Supportive Post-implant Treatment Coverage? A Systematic Review and Meta-analysis.
Authors: Lin CY, Chen Z, Pan WL, Wang HL Abstract PURPOSE: Among all previous studies, history of periodontitis (HP) has been regarded as a negative indicator for peri-implant health. However, the role of HP under regular supportive post-implant treatment (SPT) has not yet been evaluated. The aim of this review was to evaluate whether HP remains a negative indicator even under regular SPT in terms of clinical outcomes. MATERIALS AND METHODS: Two independent reviewers conducted electronic and manual searches of the literature in English from January 2003 to May 2018. Human clinical studies including both patient...

In Vitro Analysis of the Implant-Abutment Interface Connection and Bacterial Infiltration in Two Extraoral Implant Models.
Authors: de Souza RS, Suffredini IB, Cortizo DL, Larsson A, Nannmark U, Dib LL Abstract PURPOSE: To compare the connection microgaps and the bacterial infiltration of implant-abutment interfaces of two extraoral implant models. MATERIALS AND METHODS: Two implant models were used: the inner connection and the flush connection types. The implant-abutment microgaps of five sets of each extraoral implant were evaluated with scanning electron microscopy. Eleven additional sets of each model design were immersed in Staphylococcus aureus cultures for 24 hours, and samples were obtained from the external surface and fr...

Osteoconductivity of Biphasic Calcium Phosphate Ceramic Improves New Bone Formation: A Histologic, Histomorphometric, Gene Expression, and Microcomputed Tomography Study.
CONCLUSION: The use of biphasic calcium phosphate ceramic resulted in greater immature bone formation than deproteinized bovine bone at an early assessment. The studied bone regeneration genes were downregulated in comparison to the control. PMID: 31923291 [PubMed - in process] (Source: International Journal of Oral and Maxillofacial Implants)
