Vliv doplňku hořčíku (Mg) a střídavé maxilární expanze a konstrikce (Alt-RAMEC) u pacientů s příčnou maxilární deficiencí (TMD) (Mg + Alt-RAMEC)

13. září 2026 aktualizováno: IBRAHEEM RAHMA HAZIM IBRAHEEM, Universiti Sains Malaysia

Vliv doplňku hořčíku (Mg) a alternativní maxilární expanze a konstrikce (Alt-RAMEC) u pacientů s příčnou maxilární deficiencí (TMD): Randomizovaná klinická studie.

Tato randomizovaná klinická studie hodnotí účinek kombinace suplementace hořčíku s ortodontickou technikou nazývanou Střídavá expanze a konstrikce horní čelisti (Alt-RAMEC) pomocí aparátu Micro-implant Assisted Rapid Palatal Expansion (MARPE) k léčbě dospělých (18-30 let) s příčným deficitem horní čelisti (TMD). TMD je stav, kdy je horní čelist užší než obvykle, což může ovlivnit skus a vývoj obličeje.

Studie zahrnuje dvě skupiny: jedna podstupuje protokol Alt-RAMEC s MARPE samotným a druhá podstupuje stejný protokol spolu s perorálními doplňky hořčíku. Účinnost těchto léčebných postupů bude porovnána hodnocením změn v zubních a skeletálních strukturách pomocí zobrazovacích technik a vyhodnocením funkce svalů. Účastníci budou také zaznamenávat své úrovně bolesti a nepohodlí během léčby.

Tento výzkum si klade za cíl zjistit, zda suplementace hořčíku může posílit účinky léčby Alt-RAMEC, zlepšit výsledky pacientů a snížit nepohodlí spojené s ortodontickými zákroky.

Detailní popis

Tato klinická studie si klade za cíl vyhodnotit účinnost suplementace hořčíku v kombinaci s protokolem Alternativní Maxilární Expanze a Konstrikce (Alt-RAMEC) využívajícím Mikroimplantátem Podporovanou Rychlou Palatinální Expansi (MARPE) u dospělých pacientů s příčným nedostatečným rozvojem horní čelisti (TMD). Studie porovnává dvě léčebné skupiny: jedna podstupuje protokol Alt-RAMEC s MARPE samostatně a druhá podstupuje Alt-RAMEC s MARPE spolu s perorální suplementací hořčíku.

Protokol Alt-RAMEC zahrnuje řízené cykly maxilární expanze a konstrikce k usnadnění korekce příčných maxilárních odchylek. Pacienti jsou léčeni specifickými režimy aktivace a deaktivace zahrnujícími MARPE aparát po dobu několika týdnů. Tato studie hodnotí změny v dentálních, alveolárních, skeletálních a svalových strukturách pomocí pokročilých zobrazovacích metod, jako je 3D Cone Beam Computed Tomography (CBCT) a povrchová elektromyografie (sEMG). Dále budou během ortodontické léčby hodnoceny hladiny bolesti a nepohodlí hlášené pacienty.

Tato studie se zaměřuje na objektivní měření morfologických a funkčních změn za účelem zjištění, zda příjem hořčíku zvyšuje účinky léčby Alt-RAMEC a zlepšuje komfort pacientů a výsledky léčby. Zjištění mohou poskytnout cenné důkazy pro optimalizaci léčebných protokolů pro příčný nedostatečný rozvoj horní čelisti u mladých dospělých pacientů.

Aktivní komparátor: 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.

Change from Baseline in Anterior Midpalatal Suture Separation at 12 Weeks
Časové okno: 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.
Baseline, before the first MARPE activation (T0), and 12 weeks after the first MARPE activation (T1).
