(20) The mechanical strength of the porous coating on the prosthetic surface should be improved and the prosthesis should be tested in limited clinical studies before cementless fixation can be recommended.
Spongiform
Definition:
(a.) Resembling a sponge; soft and porous; porous.
Example Sentences:
