Porous bone implants
24
TL;DR: Porous conical implants made by sintering micro-spheres made from bioactive and bio-compatible glasses have been tested mechanically as well as in vivo by inserting the implant through the cortical bone into the bone marrow.

Porous architected biomaterial for a tibial-knee implant with minimum bone resorption and bone-implant interface micromotion
TL;DR: The numerical results suggest that the overall amount of bone resorption around the graded porous tibial stem is 26% lower than that around a conventional, commercially available, fully dense titanium implant of identical shape and size.

The role of strontium and potassium on crystallization and bioactivity of Na2O–CaO–P2O5–SiO2 glasses
TL;DR: In this article, the effect of the substitution of the glass oxide constituents in determining the crystallization and bioactivity behavior of the prepared thermally treated glasses was discussed. But, the role played by the glass oxides constituents in the determination of the apatite layer's surface and the surface reactivity was not discussed.

Effect of microstructure on the tensile property of porous Ti produced by powder metallurgy technique
TL;DR: In this paper, the microstructure, tensile deformation and final fracture behavior of porous Ti were investigated using PMMA as a space holder, and the failure mechanism has been discussed by taking the intrinsic microstructural features into consideration.

TL;DR: Its high modulus and brittle nature makes its applications limited, but it has been used in combination with poly-methylmethacrylate to form bioactive bone cement and with metal implants as a coating to form a calcium-deficient calcium phosphate layer.

TL;DR: Cell culture results support the potential use of synthetic porous bio-glass as an OOKP skirt material in terms of limited inflammatory potential and capacity to induce and support tissue ingrowth.

Bonding mechanisms at the interface of ceramic prosthetic materials
TL;DR: A theoretical model to explain the interfacial bonding is based upon in-vitro studies of glass-ceramic solubility in interfacial hydroxyapatite crystallization mechanisms, compared with in- vivo rat femur implant histology and ultrastructure results.

In vivo behaviour of glasses in the SiO2-Na2O-CaO-P2O5-Al2O3-B2O3 system
TL;DR: In this article, the authors used SiO2-Na2O-CaO-P2O5-Al 2O3-B2O3 system to study the bone-bonding of 16 glasses and found that up to about 1.5 wt % of Al 2 O3 can be included in the glass without destroying the bioactivity.

Evaluation of the acceptance of glass in bone
TL;DR: In this article, six glasses in the SiO2-Na2O-CaO-P2O5-Al 2O3-B2O3 system were implanted in rabbit tibia.

TL;DR: It is concluded that ZA induces the proliferation and differentiation of cells of the osteoblast lineage and TGF‐β is a potent mitogen for osteoblasts.
