Влияние добавки магния (Mg) и чередующегося расширения и сужения верхней челюсти (Alt-RAMEC) на пациентов с поперечной недостаточностью верхней челюсти (TMD) (Mg + Alt-RAMEC)
Влияние добавки магния (Mg) и чередующегося расширения и сужения верхней челюсти (Alt-RAMEC) на пациентов с поперечной недостаточностью верхней челюсти (TMD): рандомизированное клиническое исследование.
Это рандомизированное клиническое исследование оценивает эффект сочетания приёма магния с ортодонтической техникой, называемой Альтернативное расширение и сужение верхней челюсти (Alt-RAMEC), с использованием аппарата для микроимплантационно-ассистированного быстрого расширения нёба (MARPE) для лечения взрослых (18–30 лет) с поперечной недостаточностью верхней челюсти (TMD). TMD — это состояние, при котором верхняя челюсть уже, чем обычно, что может влиять на прикус и развитие лица.
Исследование включает две группы: одна получает протокол Alt-RAMEC с MARPE отдельно, а другая — тот же протокол вместе с пероральными добавками магния. Эффективность этих методов лечения будет сравниваться путём оценки изменений в зубных и скелетных структурах с помощью методов визуализации и оценки функции мышц. Участники также будут сообщать о своём уровне боли и дискомфорта во время лечения.
Это исследование направлено на понимание того, может ли приём магния усилить эффекты лечения Alt-RAMEC, улучшить результаты для пациентов и уменьшить дискомфорт, связанный с ортодонтическими процедурами.

Подробное описание
Это клиническое исследование направлено на оценку эффективности приёма магния в сочетании с протоколом попеременного расширения и сужения верхней челюсти (Alt-RAMEC) с использованием микроимплантатно-ассистированного быстрого нёбного расширения (MARPE) у взрослых пациентов с поперечной недостаточностью верхней челюсти (TMD). Исследование сравнивает две группы лечения: одна получает только протокол Alt-RAMEC с MARPE, а другая — протокол Alt-RAMEC с MARPE вместе с пероральным приёмом магния.
Протокол Alt-RAMEC включает контролируемые циклы расширения и сужения верхней челюсти для облегчения коррекции поперечных несоответствий. Пациенты проходят лечение по определённым режимам активации и деактивации с использованием аппарата MARPE в течение нескольких недель. В этом исследовании оцениваются изменения зубных, альвеолярных, скелетных и мышечных структур с помощью современных методов визуализации, таких как 3D-конусно-лучевая компьютерная томография (КЛКТ) и поверхностная электромиография (пЭМГ). Кроме того, во время ортодонтического лечения будут оцениваться уровни боли и дискомфорта, о которых сообщают пациенты.
Это исследование сосредоточено на объективном измерении морфологических и функциональных изменений, чтобы определить, усиливает ли приём магния эффекты лечения по протоколу Alt-RAMEC и улучшает ли комфорт пациента и результаты лечения. Полученные данные могут предоставить ценную информацию для оптимизации протоколов лечения поперечной недостаточности верхней челюсти у молодых взрослых пациентов.

Активный компаратор: Alt-RAMEC/MARPE Without Magnesium Supplementation
Participants receive alternate rapid maxillary expansion and constriction (Alt-RAMEC) using a micro-implant-assisted rapid palatal expansion (MARPE) appliance without magnesium supplementation.
The appliance consists of a 10-mm Maxillary Skeletal Expander II supported by four palatal miniscrews.
Activation consists of two expansion quarter-turns daily in weeks 1 and 3, one reverse quarter-turn daily in weeks 2 and 4, and one to two expansion quarter-turns daily in week 5 until the clinical expansion endpoint is reached.
Weeks 6-12 comprise passive retention and follow-up.
The appliance and activation schedule are identical to those used in the experimental arm; this arm serves as the control for evaluating the additional effects of magnesium supplementation.
