Abstract

Introduction. The evolution of rapid prototyping technologies, novel high-precision metalworking equipment, and prompt implementation of additive technologies into practice have significantly expanded the possibilities of producing new biomechanical structures. Therefore, the development of novel methods and approaches ensuring rapid and highly effective designing and manufacturing of individual implants is highly relevant. Objective – to develop a technology that allows rapid design and manufacturing of implants for maxillofacial surgery. Results. In this study, we analyzed the technology of rapid design and production of individual jaw implants based on computed tomography data, which reduced the duration of surgery by ~50 % (from 3–4 h to 2–2.5 h) and allowed one-stage surgery. We achieved high toughness of implants and excluded the risk of fatigue destruction of a biome chanical structure due to increased cyclic loads. Conclusion. Rapid production of individual jaw implants described in this article ensured high productivity of the pro cess of producing individual biomechanical structures and helped to restore the original contour of the patient’s face with significant lesions to the mandibular bone.

Summary

Introduction

The evolution of rapid prototyping technologies, novel high-precision metalworking equipment, and prompt implementation of additive technologies into practice have significantly expanded the possibilities of producing new biomechanical structures. Цель исследования – разработка процесса, обеспечивающего оперативность проектирования и изготовления имплантатов в области челюстно-лицевой хирургии. Оперативное проектирование индивидуальных челюстных имплантатов на основе данных компьютерной томографии позволяет уменьшить время проведения операции на ~50 % (c 3–4 до 2–2,5 ч) и обеспечить одноэтапность операции, а также восстановить исходный контур лица пациента, имеющего значительное поражение костных тканей.
