Bilateral total temporomandibular joint (TMJ) replacement in a patient with post-traumatic deforming TMJ osteoarthritis and occlusal relationship deformity: A clinical case; Двустороннее тотальное эндопротезирование ВНЧС у больного с посттравматическим деформирующим артрозом ВНЧС и деформацией окклюзионных взаимоотношений: клинический случай

The purpose of the study is to demonstrate an integrated approach to the rehabilitation of a patient with ankylosis, traumatic deformation of the condylar processes of the mandible and malocclusion by introducing into the standard protocol elements of cephalometric analysis in planning the position of the mandible. Materials and methods. Patient 55 years old with a bilateral intracapsular crushed fracture of the articular heads, right and left condylar processes of the lower jaw with displacement of bone fragments, unstable, pathological bite, absence of teeth 1.5, 2.6, 3.6, 3.7, 4.6, and 4.7. Results. The first stage involved bilateral extraction of the articular heads and condylar processes of the lower jaw by resection of incorrectly consolidated bone fragments using resection templates. Then the splint was placed and the artificial articular fossa made of PEEK and articular heads made of titanium were fixed using titanium mini-screws. To restore the physiological bite, the second stage (after 30 days) orthopedic treatment was carried out using an occlusal splint to register the bite, dental implants and all-ceramic crowns. Conclusion. The obtained treatment result indicates the significant role of computer planning and normalization of physiological occlusion when carrying out reconstructive interventions for fractures in the area of the condylar processes in complex forms of malocclusion. © 2025 Elsevier B.V., All rights reserved.
