The invention relates to an implant for the human or animal body, which on its outer surface comprises at least one calcium salt that is soluble in a polar liquid. The invention also refers to various methods for the preparation of the preceding implant. The calcium ions contained on the surface of the implant provide said surface with four chemically and biologically advantageous properties: hydrophilicity, protection against atmospheric contamination, a pro-coagulant property and a pro-mineralising property.本發明關於一種用於人體或動物體之植入物,其外表面上係包含至少一種可溶於極性液體之鈣鹽。本發明亦關於各種製備前述植入物的方法。該植入物之表面上所含有的鈣離子對該表面提供四種化學上及生物上有利之性質:親水性、對抗大氣污染之保護、促凝血性質、及促礦化性質。
