OSTEOSYNTHESIS OF MANDIBULAR FRACTURES USING CONSTRUCTIONS MADE OF TITANIUM NICKELIDE

Abstract

Purpose. Development of new medical technology of surgical treatment of patients with mandibular fractures using materials with shape memory. Materials and methods. With the use of fixing structures made of titanium nickelide with shape memory, developed in the research Institute of medical materials and implants with shape memory, surgical treatment of more than 2,000 patients, both sexes, aged 13 to 80 years, with fractures of the lower jaw of various nature and localization of intraoral or extraoral accesses without immobilization of the lower jaw and combination with other methods of osteosynthesis. Results. The use of fixing structures with thermomechanical memory in the surgical treatment of various types of mandibular fractures allowed to obtain satisfactory results in 95.5% of patients. In the remaining 4.5% of cases there were complications in the form of suppuration of bone wounds, traumatic osteomyelitis, which is associated with late treatment and/or inhibition of reparative function, delayed consolidation, mainly in older and elderly people, as a result of trophic disorders. Conclusion. Due to the biocompatibility of titanium nickelide with tissues of the body, osteosynthesis of mandibular fractures using staples from this material allows to minimize all kinds of complications inherent in this type of intervention.
