Reliability enhancement of medical implants through using innovative manufacturing and coating techniques

Project goal
The research aims to develop new innovative biocompatible coatings and related technological processes for the effective manufacture of affordable medical adaptive orthopedics implants with improved biocompatibility and osseointegration properties.

Project tasks:

1. Comprehensive analysis of titanium alloys for medical implants and different techniques of coatings with bioactive materials
2. Development of advanced technologies for the effective production of small-scale samples of titanium medical implants with bioactive coatings
3. In vitro analysis of small-scale samples of titanium medical implants with bioactive coatings for biocompatibility and antibacterial activity
4. Development of 2 types of medical implants prototypes and their quality characterization

Abstract: Currently, the priority direction of solving problems related to public health protection is the development of high-tech competitive technologies to produce affordable medical products that meet international quality standards, particularly metal implants for dentistry and orthopedics, and are patient-specific or adaptive. Such implants are needed to speed up the patient’s recovery, reduce the risk of post-surgery complications associated with implant rejection, and ensure long service life. Nowadays, more than 5% of embedded implants are rejected by the patient’s body due to the development of bone necrosis, which occurs when the implant surface is destroyed, deformed, and metal particles penetrate the surrounding tissues of the body; or due to the development of periprosthetic bacterial infections. Therefore, the development of new technologies for surface treatment of medical implants to increase their biocompatibility, ensure their non-toxic and antibacterial properties, and provide osteoconductivity osseointegration to shorten the patient’s recovery time and prolong the life of the implant is of great importance. In this project, we propose additive manufacturing of metal products by selective laser melting, and development of innovative coatings from biocompatible materials with controlled structure and properties, and the automation of related technological processes to produce affordable medical implants for dentistry and orthopedics.
