A distinct nosological entity among temporomandibular joint disorders is forced mandibular position syndrome, a pathological condition characterized by compensatory or non-physiological displacement of the mandible. The clinical presentation of this syndrome is polymorphic and includes a complex of specific clinical and paraclinical signs, such as myoarticular dysfunction, occlusal disturbances, pain in the temporomandibular joint region, and other impairments of the masticatory and speech apparatus. A key component of rehabilitation in this condition is verification of the vector of mandibular displacement followed by registration of the centric relation. Successful completion of this stage establishes the foundation for subsequent restoration of physiological occlusal relationships and normalization of mandibular articulatory movements. The treatment protocol included clinical and laboratory stages of temporary and definitive prosthetic rehabilitation. At the first stage, a removable stabilization splint was used to reposition the mandible. The splint was fabricated following transcutaneous electrical nerve stimulation and prescribed for 24 hours per day wear. After 6 months of splint therapy, provisional restorations were fabricated in the newly established maxillomandibular relationship. At the final stage, definitive fixed denture constructions with combined support (teeth and implants) were delivered. Because forced mandibular position syndrome manifests as a constellation of specific symptoms, its diagnosis and management must be individualized. The presented clinical case demonstrates that staged treatment according to the proposed comprehensive protocol improves rehabilitation outcomes in patients with this condition.</p></abstract><trans-abstract xml:lang="ru"><p>Клинические исследования отечественных и зарубежных авторов показывают, что заболевания височно-нижнечелюстного сустава и жевательной мускулатуры являются распространённой стоматологической патологией. Особое место среди нозологических форм заболеваний височно-нижнечелюстного сустава занимает синдром вынужденного положения нижней челюсти, представляющий собой патологическое состояние, в основе которого лежит компенсаторное или нефизиологическое смещение нижней челюсти. Клиническая картина данного синдрома характеризуется полиморфизмом и включает комплекс специфических клинико-параклинических признаков, таких как миоартикулярная дисфункция, окклюзионные нарушения, болевой синдром в области височно-нижнечелюстного сустава, а также иные расстройства функции жевательно-речевого аппарата. Ключевым элементом реабилитационных мероприятий при данной патологии является верификация вектора смещения нижней челюсти с последующей регистрацией центрального соотношения челюстей. Успешное выполнение данного этапа формирует основу для последующего восстановления физиологических окклюзионных взаимоотношений и нормализации траектории артикуляционных движений нижней челюсти. Протокол лечения включал клинико-лабораторные этапы временного и постоянного протезирования. На 1-м этапе для позиционирования нижней челюсти использовали съёмную стабилизирующую капу, изготовленную после проведения чрескожной электронейростимуляции, с режимом ношения 24 ч в сутки. Через 6 мес. пациенту проведено изготовление временных (провизорных) реставраций в сформированном соотношении зубных рядов после лечения на капе. На заключительном этапе были изготовлены несъёмные ортопедические конструкции с комбинированной опорой — на зубах и имплантатах. Поскольку синдром вынужденного положения нижней челюсти проявляется совокупностью специфических симптомов, его диагностика и терапия должны подбираться индивидуально для каждого пациента. На примере клинического случая в статье показано, что поэтапное лечение по предложенной комплексной методике повышает успешность реабилитации пациентов с данной патологией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>forced mandibular position syndrome</kwd><kwd>stabilization splint</kwd><kwd>habitual occlusion</kwd><kwd>centric relation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>синдром вынужденного положения нижней челюсти</kwd><kwd>стабилизирующая капа</kwd><kwd>привычная окклюзия</kwd><kwd>центральное соотношение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Fadeev RA, Parshin VV, Prozorova NV.
