Calcium phosphates (CaP) are the most commonly used group of bioceramic compounds due to their good biocompatibility, osseointegration and osteoconductivity. Their application is wide, but they are best known for use in dental and orthopedic medicine where, due to their chemical similarity to mammalian bones, they are used as coatings on implants. Implants represent a replacement/substitution of a damaged part of bone or tissue and are designed with the aim of restoring function to the damaged part of the body. The most commonly used implant materials are metals and their alloys such as titanium, stainless steel and cobaltchromium alloys. In tissue engineering for bone regeneration and osseointegration, the implant surface is modified by calcium-phosphate coatings (CaP coatings), which improve and accelerate the processes of bone growth and fixation. CaP coatings increase bioactivity, biocompatibility, corrosion resistance and other biomechanical properties of implant systems. There are numerous methods of preparing CaP coatings, the most common of which are described in this work. One of the most widely used method is electrochemical deposition, a low-temperature method with high availability and low cost of equipment. Due to high proportion of the elderly population, and increasingly frequent bone diseases and degenerative and inflammatory conditions (including necrosis and osteoporosis), the use of tissue engineering, i.e., the need for bone and tissue regeneration, is increasing so that the development and improvement of implant systems with CaP coatings are the subject of constant research.
