Introduction. Fractures of the condyle process of the lower jaw are one of the most common types of its trau-matic lesions. According to the literature, 25-40 % of fractures of the lower jaw are localized in the condyle process. Among them, 25-30 % are the most difficult to diagnose and treat fractures of the head of the lower jaw.
The aim of this study was to evaluate the clinical and functional efficacy of navigation templates and patient-specific retainers in patients with a mandibular head fracture compared to traditional methods of osteosynthesis.
The material of this study was 37 patients with 48 frac-tures of the head of the lower jaw (31 men and 6 women, aged 19 to 61 years, mean age 38 ± 11.8 years). Depend-ing on the method of osteosynthesis of the lower jaw head, all patients were divided into 2 groups, uniform in age, gender and severity of injury.
Patients in both groups were examined according to a standard scheme that included Anamnesis collection, as-sessment of general and local status, and the use of la-boratory and instrumental research methods.
The use of navigation surgical templates and patient-specific retainers in patients with a fracture of the head of the lower jaw can improve the anatomical and functional results of their surgical treatment, namely, to increase the accuracy of restoring the anatomical shape of the head, reduce the frequency of occlusive disorders and second-ary displacements, as well as increase the maximum range of movements of the lower jaw by 6.4-20 %.
