“…HA can form a direct chemical bond with adjacent bone tissue and facilitates rapid osseointegration of implants. Acceleration of the process of osteosynthesis in orthopedics is a key factor, as this leads to a reduction in the duration of treatment of patients, and consequently to a reduction in the economic costs of medical discussion [1][2][3][4][5][6][7][8][9][10][11].…”

Calcium apatite and sodium alginate based composite material with ZnO microparticles doping Among the various materials for orthopedic use, hydroxyapatite (HA) is the most common material, due to its chemical similarity to bone. However, the application is limited because of low mechanical properties (especially high brittleness), low water solubility, low antimicrobial activity. The introduction of trace metal ions, as well as biopolymers, can improve its properties. The present work is devoted to the synthesis and complex study of bioactive material based on nanostructured hydroxyapatite with the addition of sodium alginate and ZnO, which has properties close to bone tissue. The article presents information on the method of preparation and the results of the investigation of a new composite material based on HA and sodium alginate with the addition of ZnO microcrystals. In the research work next methods were used: scanning electron microscopy with the possibility of energy-dispersion analysis, transmission electron microscopy and IR spectroscopy. The morphology, the particles phase statesare described, the regularities of the structural features of the new material are revealed. The main characteristics like, the ratio of Ca/P and functional groups correspond to the generally accepted parameters. An explanation of the grouping of ZnO microcrystals in the pores of the structure of a synthesized composite material is proposed.

: Titanium (Ti) and its alloys are potential metal materials in dental and orthopedic applications, due to excellent comprehensive mechanical properties and biocompatibility. Despite this, revision surgery is painful for millions of patients and may cause secondary injury. Nowadays, it is time to solve the tricky problem. Compared with the clinically used antibiotics, novel biomaterials displayed powerful application potential due to their stronger antibacterial activity, less drug resistance and excellent biocompatibility. Antibacterial ions have a crucial effect, especially for nanostructured metal. The review mainly aims at the antibacterial function and osteogenic properties about surface modification based on Ag ions, Zn ions, Cu ions and other nonmetallic ions. The first part of the present review briefly described the problem of the bacterial infection of Ti implants. Then the methods of surface modification were detailed introduced. At last, other strategies, which were used to improve antibacterial and osteogenic properties were mentioned. Although anti-infective research is fruitful, there are some problems to be solved between mentioned and clinically implemented strategies. It is urgent to transform study into clinical application.
