Experimental substantiation of the use of hydroxyapatite - tricalcium phosphate bioceramics for replacing bone defects after tumor removal.

Background: Recently, bioactive ceramics based on hydroxyapatite (HAP) and tricalcium phosphate (TCP) have been preferred as implants in bone engineering.

Aim: To study bone regeneration under conditions of filling metaphyseal defects with the original HAP-TCP composition.

Materials And Methods: The experiment was carried out on inbred rats, the observation period was 2, 4, 8 weeks.
