摘要：
The invention relates to medicine, and more particularly to maxillofacial surgery, and can be used in the manufacture of implants for the combined surgical and orthopaedic rehabilitation of patients with facial bone defects. The aim and the technical result of the invention are the creation of a standard implant design for use in mandibular prosthetic reconstruction, which provides for tailored alignment with the region of the skull undergoing reconstruction and provides for the necessary elastic properties of the implant, namely a porous structure with an elasticity modulus of 1-5 hPa and a compressive strength of 50 kg/cm2. The technical result is achieved in that an implant for mandibular prosthetic reconstruction comprises a plate which is made of titanium or an alloy thereof and is provided with fastening elements having through-openings for the passage of fastening screws, wherein the plate is provided at one end with an element having a three-dimensional continuous structure which conforms to the shape of the condyloid process, the plate itself has a three-dimensional porous structure having the shape of the body of the mandible, and the plate is provided at the other end with an osseointegration element having a three-dimensional porous structure, and also with two fastening elements in the form of narrow perforated plates, wherein the cells of the porous structure are in the form of a tetrahedron, dodecahedron or an octahedron and are provided with a plurality of spacers having a circular and/or rectangular cross section.L'invention se rapporte au domaine de la médecine, notamment de la chirurgie maxillo-faciale et peut être utilisée afin de fabriquer un implant lors d'une réhabilitation chirurgicale et orthopédique complexe de patients présentant des défauts osseux du crâne facial. Le but et le résultat technique de la présente invention consistent en la création d'une structure type d'implant pour la prothétisation de la mâchoire inférieure, assurant une
