“…However, owing to their brittle nature, they are not suitable to be used in the bulk form or for load-bearing applications [ 20 , 21 ]. To overcome this issue, HAp can be used as thin film coatings on other groups of materials for bone-graft material applications [ 22 , 23 ]. According to previous works, the modification of materials with HAp ceramic coatings can improve the bioactivity, osteoconductivity, osteoinductivity, and resorbability of composite biomaterials [ 7 , 24 , 25 ] Meanwhile, HAp can also be used in its fine-powder forms as a filler, for example in tablets and capsules, to make the medicines easier to measure [ 26 ].…”

The application of various materials in biomedical procedures has recently experienced rapid growth. One area that is currently receiving significant attention from the scientific community is the treatment of a number of different types of bone-related diseases and disorders by using biodegradable polymer-ceramic composites. Biomaterials, the most common materials used to repair or replace damaged parts of the human body, can be categorized into three major groups: metals, ceramics, and polymers. Composites can be manufactured by combining two or more materials to achieve enhanced biocompatibility and biomechanical properties for specific applications. Biomaterials must display suitable properties for their applications, about strength, durability, and biological influence. Metals and their alloys such as titanium, stainless steel, and cobalt-based alloys have been widely investigated for implant-device applications because of their excellent mechanical properties. However, these materials may also manifest biological issues such as toxicity, poor tissue adhesion and stress shielding effect due to their high elastic modulus. To mitigate these issues, hydroxyapatite (HA) coatings have been used on metals because their chemical composition is similar to that of bone and teeth. Recently, a wide range of synthetic polymers such as poly (l-lactic acid) and poly (l-lactide-co-glycolide) have been studied for different biomedical applications, owing to their promising biocompatibility and biodegradability. This article gives an overview of synthetic polymer-ceramic composites with a particular emphasis on calcium phosphate group and their potential applications in tissue engineering. It is hoped that synthetic polymer-ceramic composites such as PLLA/HA and PCL/HA will provide advantages such as eliminating the stress shielding effect and the consequent need for revision surgery.

“…The development of implant materials for orthopaedics and dental replacement inserted in the human body has attracted considerable attention in recent years [1][2][3]. Implant materials should have good mechanical strength, high chemical stability, high degree of crystallinity, high corrosion resistance, low toxicity and excellent biocompatibility [4,5]. Hydroxyapatite (HA) is a biocompatible and bioactive material which has attracted much attention, but the brittle nature of HA ceramic limits its clinical use in a load-bearing situation [6][7][8].…”

In this paper, the influence of different laser power and scanning speed on the microstructure of laser remelted as-sprayed hydroxyapatite (HA) coatings was studied and the optimum technological parameters were obtained. The morphologies, elements and phase analysis of both sprayed and remelted coatings were examined by means of electron probe microanalysis, x-ray diffraction and so on. The results show that the plasma sprayed coatings could be improved by laser remelting and the optimum technological parameters are that the laser power is 600 W and the scanning speed is 11.2 mm s−1. In the technological condition, the remelted coating which has compact columnar and cellular dendritic crystal consists of HA, α-TCP, CaO and TiO2 phases, and the Ca/P ratio of the coating is the most approximate to that of HA. When increasing the laser power and slowing the scanning speed, the structure of the coating will become much coarser and the Ca/P ratio will deviate more from that of HA. On the contrary, if the laser power is reduced and the scanning speed is accelerated, the influence of technological parameters of laser remelting on the sprayed coating will be weakened.
