A Magnézium (Mg) kiegészítés és a váltakozó maxilláris tágítás és szűkítés (Alt-RAMEC) hatása a transzverzális maxilláris deficienciával (TMD) rendelkező betegeken (Mg + Alt-RAMEC)
A magnézium (Mg) kiegészítő és a váltakozó maxillaris tágítás és szűkítés (Alt-RAMEC) hatása a transversális maxillaris deficiencia (TMD) betegeiben: egy randomizált klinikai vizsgálat.
Ez a randomizált klinikai vizsgálat azt értékeli, hogy a magnézium-kiegészítés és az Alternáló Maxillaris Tágítás és Szűkítés (Alt-RAMEC) nevű ortodontiai technika kombinációja milyen hatással van felnőttek (18-30 év) transzverzális maxillaris hiányosságának (TMD) kezelésére, miközben Mikroimplantátummal Segített Gyors Szájpad-tágító (MARPE) készüléket alkalmaznak. A TMD egy olyan állapot, amelyben a felső állkapocs szűkebb, mint a normális, ami befolyásolhatja a harapást és az arckifejlődést.
A tanulmány két csoportot foglal magában: az egyik csak az Alt-RAMEC protokollt kapja MARPE-vel, míg a másik ugyanezt a protokollt kapja orális magnézium-kiegészítőkkel együtt. E kezelések hatékonyságát a fogászati és csontvázszerkezetek képalkotó technikákon keresztül történő változásainak értékelésével és az izomfunkció vizsgálatával hasonlítják össze. A résztvevők a kezelés alatti fájdalom- és kellemetlenségszintjeiket is jelentik.
Ez a kutatás azt kívánja megérteni, hogy a magnézium-kiegészítés fokozhatja-e az Alt-RAMEC kezelés hatásait, javíthatja-e a betegek eredményeit, és csökkentheti-e az ortodontiai eljárásokhoz kapcsolódó kellemetlenségeket.

Részletes leírás
Ez a klinikai vizsgálat a magnézium-kiegészítés és az Alternatív Maxilláris Tágítás és Szűkítés (Alt-RAMEC) protokoll kombinációjának hatékonyságát értékeli, Micro-Implantátummal Segített Gyors Szájpad-tágítás (MARPE) alkalmazásával felnőtt pácienseknél, akiknél transversális maxilláris deficiencia (TMD) áll fenn. A tanulmány két kezelési csoportot hasonlít össze: az egyik az Alt-RAMEC protokollt kapja MARPE-vel együtt, a másik pedig az Alt-RAMEC protokollt MARPE-vel, valamint orális magnézium-kiegészítéssel.
Az Alt-RAMEC protokoll a maxilláris tágítás és szűkítés szabályozott ciklusait foglalja magában, hogy elősegítse a maxilláris transversális eltérések korrekcióját. A pácienseket specifikus aktiválási és deaktiválási szabályokkal kezelik, amelyek a MARPE készüléket érintik több hét alatt. Ez a tanulmány a fogászati, alveoláris, csontváz- és izomszerkezetek változásait értékeli, fejlett képalkotó technikák, például 3D Cone Beam Computed Tomography (CBCT) és felszíni elektromiográfia (sEMG) segítségével. Ezen kívül a páciensek által jelentett fájdalom és kellemetlenség szintjét is értékelik az ortodontiai kezelés során.
Ez a vizsgálat a morfológiai és funkcionális változások objektív mérésére összpontosít, annak meghatározására, hogy a magnézium-bevitel fokozza-e az Alt-RAMEC kezelés hatásait, és javítja-e a páciensek kényelmét és a kezelés eredményeit. A megállapítások értékes bizonyítékokat nyújthatnak a transversális maxilláris deficiencia kezelési protokolljainak optimalizálásához fiatal felnőtt pácienseknél.

Aktív összehasonlító: 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.
