Interfacial tensile strength between polymethylmethacrylate-based bioactive bone cements and bone

OsteoInk: Bioactive Bone Cements

Bactericidal strontium-releasing injectable bone cements based on bioactive glasses.

Strontium-releasing injectable bone cements may have the potential to prevent implant-related infections through the bactericidal action of strontium, while enhancing bone formation in patients suffering from osteoporosis. A melt-derived bioactive glass (BG) series (SiO2–CaO–CaF2–MgO) with 0–50% of calcium substituted with strontium on a molar base were produced. By mixing glass powder, poly(ac...

Regional variation in shear strength of the bone-polymethylmethacrylate interface.

Many investigators consider the polymethylmethacrylate-bone interface the weakest link in the bone-cement-implant system. Push-out tests, frequently used for in vitro evaluation of the bone-cement interface, produced inconsistent results of shear strength. Therefore, a more reliable model for testing the shear failure of the interface was developed. Better understanding of intrinsic variations ...

Evaluation of Tensile Bond Strength between Dentin and Metallic Copings Using Different Resin Cements

Statement of the Problem: For a successful clinical outcome, luting agents should have a high bond strength. Bond failure is still one of the main reasons of restoration failures. Purpose: The present study was designed to comparatively evaluate the retention of metallic copings using different resin luting cements. Materials and Method: In the present experimental study, 40 intact premolar tee...

No increased bone formation around alendronate or omeprazole loaded bioactive bone cements in a femoral defect.

Alendronate and omeprazole have been found to influence bone healing by interfering with osteoclastic activity, resulting in increased bone formation. The biological effect of these conventional drugs, incorporated into bioactive bone cement (G2B1), was investigated in a rabbit model. The 2 materials and a control were inserted in defects created in the femoral condyle of rabbits. Implantation ...
