The methods of perfecting the surface of titanium alloy-based endoprostheses used in pediatric oncology

Abstract

The rehabilitation of pediatric patients with oncology diseases localized in the maxillofacial area is a complex and long-term process. Most frequently, the resection area involves the maxilla or the mandible, which, in turn, impairs the functioning of the whole dentofacial system. The restoration of the integrity of the facial structures is the key task in the treatment of such patients. One of the main materials used for reconstructing the jaws is the titanium alloy. However, despite its beneficial properties and characteristics, there is a high risk of inflammation, encapsulation or failure of the endoprosthesis. The aim of the research was to analyze the data available up to date on the methods of perfecting the surfaces of titanium endoprostheses based on the published research works. After analyzing the articles devoted to the modification of the surface of titanium constructions used for endoprosthetics, for the period from 2008 until 2022 (n=41), we came to a conclusion that the modification of the surface of titanium endoprostheses results in an increase in its osteointegration, which decreases the risks of failure for the constructions.
