إنجليزي. Hydroxyapatite is used for bone reconstruction, in order to improve its mechanical properties different substances can be added. In our study new biomaterial is created from deproteinised hydroxyaptite and endodentic cement, its mechanical properties were tested. Material was implanted subcutaneous in rats, then histological and biocompatability tests were performed. Results indicate that stuff has good mechanical properties, short setting time and gradual resorption creating porosity and ability to integrate in bone.

Šajā darbā biomateriāls ir veidots uz dabiska deproteinizēta hidroksiaptīta un endodentīna cementa bāzes, un noteiktas tā mehāniskās īpašības. Materiāls tika implantēts laboratorijas žurku zemādā un veikta histoloģiskā analīze kā arī noteikta biosaderība. Rezultāti rāda, ka materiālam ir piemērotas mehāniskās īpašības kaula sanācijai, īss cietēšanas laiks un pakāpeniskas rezorbcijas rezultātā veidojas poras, kas ir pie mērotas kaulaudu integrācijai.
