Biomaterials are engineering products that widely used in many medical fields such as orthopaedic applications, facial and maxillofacial surgery, artificial heart parts, metal parts implantable devices. These materials medicine because they compatible with the organism, not allergic, resistant to physical chemical factors. Hydroxyapatites bioactive calcium phosphate ceramics tissues. To increas...

This work aims to explain the effects of sonication periods, ranging from 0 4 h with a step 1 h, on morphology and structural properties Ni-doped hydroxyapatites at constant amount 0.4 at.%. The lattice parameters, crystallinity, crystallite size were affected by time. Among sonicated samples, it was observed that increasing period reduced c/a ratio. It also found ultrasonication duration.

Introduction. The loss of the jaw bone, especially in area alveolar process, can significantly complicate procedure prosthetic rehabilitation patients. reason for bones are physiological and pathological processes. Materials. Bone replacements widely used reconstruction bone defects. optimal characteristics these materials biocompatibility, bioinertness, biofunctionality a special canalicular i...
