The poroaccessibility of the intraosseous implant porous coating outer layer can be evaluated by the following parameter set  The MSCScaffold prototype structural accessibility for ingrowing bone tissue can be assessed by the proposed parameters set 

The effective pore depth p_{def}  The effective height H_{ef} 
The representative pore size p_{Srep}  The representative interspike distance D_{isrep} 
The effective volumetric porosity ϕ_{Vef}  The relative volume fraction of the interspike space ϕ_{Visef} = f(H_{ef}, D_{isrep}) 
The representative surface porosity ϕ_{Srep}  The relative surface fraction of the interspike compartment crosssection ϕ_{Sisrep} = f(D_{isrep}) 
The index of the porous coating outer layer space capacity V_{PM}  The index of the capacity of the interspike space V_{is} = f(H_{ef}, D_{isrep}) [mm^{3}/cm^{2}] 
The representative angle of the poroaccessibility Ω_{rep}  The representative angle of the interspike space osteoaccessibility Ω_{repis} = 90°−α_{i}/2, where α_{i} is the vertical angle of spikes 
The boneimplant interface adhesive surface enlargement index ψ  The boneimplant interface adhesive surface enlargement index ψ_{is} = f(H_{ef}, Ω_{repis})
