The set of stereometric parameters for characterization of the poroaccessibility of intraosseous implant porous coating outer layers and the equivalent parameters proposed for determination of the interspike structural-osteoconductive potential in the MSC-Scaffold prototype.
The poroaccessibility of the intraosseous implant porous coating outer layer can be evaluated by the following parameter set | The MSC-Scaffold prototype structural accessibility for ingrowing bone tissue can be assessed by the proposed parameters set |
---|---|
The effective pore depth pdef | The effective height Hef |
The representative pore size pSrep | The representative interspike distance Dis-rep |
The effective volumetric porosity ϕVef | The relative volume fraction of the interspike space ϕVis-ef = f(Hef, Dis-rep) |
The representative surface porosity ϕSrep | The relative surface fraction of the interspike compartment cross-section ϕSis-rep = f(Dis-rep) |
The index of the porous coating outer layer space capacity VPM | The index of the capacity of the interspike space Vis = f(Hef, Dis-rep) [mm3/cm2] |
The representative angle of the poroaccessibility Ωrep | The representative angle of the interspike space osteoaccessibility Ωrep-is = 90°−αi/2, where αi is the vertical angle of spikes |
The bone-implant interface adhesive surface enlargement index ψ | The bone-implant interface adhesive surface enlargement index ψis = f(Hef, Ωrep-is) |
