Les effets d'une supplémentation en magnésium (Mg) et de l'expansion et de la constriction maxillaires alternées (Alt-RAMEC) chez les patients présentant une déficience maxillaire transversale (DMT) (Mg + Alt-RAMEC)

13 septembre 2026 mis à jour par: IBRAHEEM RAHMA HAZIM IBRAHEEM, Universiti Sains Malaysia

Les effets d'une supplémentation en magnésium (Mg) et de l'expansion et constriction maxillaire alternée (Alt-RAMEC) chez les patients présentant une déficience maxillaire transversale (TMD) : un essai clinique randomisé.

Cet essai clinique randomisé évalue l'effet de la combinaison d'une supplémentation en magnésium avec une technique orthodontique appelée Expansion et Constriction Maxillaire Alternée (Alt-RAMEC) utilisant un appareil d'Expansion Rapide Palatine Assistée par Micro-implants (MARPE) pour traiter les adultes (18-30 ans) présentant une déficience transversale maxillaire (DTM). La DTM est une condition où la mâchoire supérieure est plus étroite que la normale, ce qui peut affecter l'occlusion et le développement facial.

L'étude implique deux groupes : l'un recevant le protocole Alt-RAMEC avec MARPE seul, et l'autre recevant le même protocole accompagné de suppléments oraux de magnésium. L'efficacité de ces traitements sera comparée en évaluant les changements dans les structures dentaires et squelettiques grâce à des techniques d'imagerie et en évaluant la fonction musculaire. Les participants rapporteront également leurs niveaux de douleur et d'inconfort pendant le traitement.

Cette recherche vise à comprendre si la supplémentation en magnésium peut améliorer les effets du traitement Alt-RAMEC, améliorer les résultats des patients et réduire l'inconfort associé aux procédures orthodontiques.

Description détaillée

Cet essai clinique vise à évaluer l'efficacité d'une supplémentation en magnésium combinée au protocole d'expansion et de constriction maxillaires alternées (Alt-RAMEC) utilisant l'expansion palatine rapide assistée par micro-implants (MARPE) chez des patients adultes présentant une déficience transversale maxillaire (DTM). L'étude compare deux groupes de traitement : l'un recevant le protocole Alt-RAMEC avec MARPE seul, et l'autre recevant Alt-RAMEC avec MARPE ainsi qu'une supplémentation orale en magnésium.

Le protocole Alt-RAMEC implique des cycles contrôlés d'expansion et de constriction maxillaires pour faciliter la correction des écarts transversaux maxillaires. Les patients sont traités avec des régimes spécifiques d'activation et de désactivation impliquant l'appareil MARPE sur plusieurs semaines. Cette étude évalue les changements dans les structures dentaires, alvéolaires, squelettiques et musculaires en utilisant des techniques d'imagerie avancées telles que la tomographie volumique à faisceau conique 3D (CBCT) et l'électromyographie de surface (sEMG). De plus, les niveaux de douleur et d'inconfort rapportés par les patients seront évalués pendant le traitement orthodontique.

Cet essai se concentre sur la mesure objective des changements morphologiques et fonctionnels pour déterminer si l'apport en magnésium améliore les effets du traitement Alt-RAMEC et améliore le confort des patients et les résultats du traitement. Les résultats pourraient fournir des preuves précieuses pour optimiser les protocoles de prise en charge de la déficience transversale maxillaire chez les jeunes patients adultes.

Intervention / Traitement
Comparateur actif: 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.
Dispositif: Micro-implant-Assisted Rapid Palatal Expansion (MARPE) With the Alt-RAMEC Protocol
Participants receive alternate rapid maxillary expansion and constriction (Alt-RAMEC) using a micro-implant-assisted rapid palatal expansion (MARPE) appliance. The appliance consists of a 10-mm Maxillary Skeletal Expander II supported by four palatal miniscrews, each 1.8 mm in diameter and 11 mm in length. 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 same appliance and activation protocol are used in both study arms.
Expérimental: Alt-RAMEC/MARPE With Magnesium Citrate Supplementation
Participants receive alternate rapid maxillary expansion and constriction (Alt-RAMEC) using a micro-implant-assisted rapid palatal expansion (MARPE) appliance, together with oral magnesium citrate providing 400 mg of elemental magnesium daily, administered as three capsules with food for 12 weeks from the first day of activation. 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, while magnesium supplementation continues.

Délai
Change from Baseline in Anterior Midpalatal Suture Separation at 12 Weeks
Délai: Baseline, before the first MARPE activation (T0), and 12 weeks after the first MARPE activation (T1).
Change in anterior midpalatal suture separation measured in millimetres (mm) using cone-beam computed tomography (CBCT) at the anterior nasal spine (ANS) level. Measurements are assessed before the first activation of micro-implant-assisted rapid palatal expansion (MARPE; T0) and 12 weeks after activation begins (T1). The change is calculated as the T1 measurement minus the T0 measurement. Positive values indicate increased separation at the anterior part of the midpalatal suture. Changes are compared between participants receiving the alternate maxillary expansion and constriction (Alt-RAMEC) protocol with magnesium supplementation and those receiving the same protocol without magnesium supplementation.

Participant-reported overall pain intensity experienced during the active alternate maxillary expansion and constriction (Alt-RAMEC) treatment period, assessed at the 12-week visit using a 0-10 pain intensity scale. A score of 0 indicates no pain or discomfort, and a score of 10 indicates the worst imaginable pain or discomfort. Higher scores indicate greater pain intensity.
