Beschreibung
Zusammenfassung:	The invention relates to a biomimetic biodegradable composition for making osseous implants, consisting of an organic phase comprising 30...70% hydroxyethylmethacrylate, 30...70% polycaprolactone dimethacrylate, 0.5...3% diethylene glycol dimethacrylate within which there is dispersed an inorganic material comprising 40...60% hydroxyapatite or tricalcium phosphate previously treated in order to create an affinity to the filler/polymer matrix interface. The composition as claimed is made of two components to be mixed before use and to be cured in a dual system of chemical and photochemical UV polymerization. Prezenta invenţie se referă la o compoziţie biodegradabilă biomimetică, pentru confecţionarea de implanturi osoase, formată dintr-o fază organică, constituită din 30...70% hidroxietilmetacrilat, 30...70% policaprolactonă dimetacrilat, 0,5...3% dietilenglicol dimetacrilat, în care se dispersează material anorganic constând din 40...60% hidroxiapatită sau fosfat tricalcic tratat în prealabil, pentru crearea unei afinităţi la interfaţa umplutură/matrice polimerică. Compoziţia este concepută sub forma a două componente care se amestecă înaintea utilizării, cu întărire în sistem dual de polimerizare chimică şi fotochimică în UV.
