Abstract
Metallic implants are widely used in the field of implantology, but there are still problems leading to implant failures due to weak osseointegration, low mechanical strength for the implant, inadequate antibacterial properties, and low patient satisfaction. Implant failure can be caused by bacterial infections and poor osteointegration. To improve the implant functionalization, many researchers focus on surface modifications to prepare the proper physical and chemical conditions able to increase biocompatibility and osteointegration between implant and bone. Improving the antibacterial performance is also a key factor to avoid the inflammation in the human body. This paper is a brief review for the types of coatings used to increase osseointegration and biocompatibility for the successful use of metal alloys in the field of implantology.
Highlights
Metallic implants are widely used in the field of implantology, but there are still problems leading to implant failures due to weak osseointegration, low mechanical strength for the implant, inadequate antibacterial properties, and low patient satisfaction
Inserting implants into living organisms must be carried out in accordance with the natural conditions of living systems; considering that the functionality of the human body is achieved through the normal activity of each physiological system, any organ dysfunction is transmitted to the whole living system [1]
Laser treatments are employed for covering the surfaces of metal implants with thin layers; these are sometimes structured at micro- and nanolevel obtained by more sophisticated or simpler chemical and electrochemical techniques that are overall more efficient than the bare metal surface
Summary
Inserting implants into living organisms must be carried out in accordance with the natural conditions of living systems; considering that the functionality of the human body is achieved through the normal activity of each physiological system, any organ dysfunction is transmitted to the whole living system [1]. To increase and improve the mechanical, chemical, and biological (biocompatibility, antimicrobial, and drug release) performances of metallic implants, a multitude of coatings have been proposed and investigated [17]. Functional coatings such as calcium phosphate coatings [2], titanium oxides [18], composite coatings [19], multilayer coatings [20,21], polymeric coatings [22], or antibacterial coatings [23] were used by surface modification techniques. Protect the host’s defense system; Achieve long-term implant fixation; Minimize implant-associated infection; Biocompatible; Facilitate the biological fixation of the implant in the human body; Promote osteointegration; Promote cell proliferation; Facilitate cell proliferation, tissue repair and growth, and the delivery of biomolecules; Biodegradable
