最近遇到兩個小插曲，讓珊醫師決定要大家聊聊現今兒童牙醫界裝置 – MRC！
我們一位病人朋友帶她孩子來諮詢，想知道孩子需不需要做矯，當時珊醫師經診斷後認為孩子情況需要這麼介入，於是建議他們每隔一段時間回來追蹤（如果沒有情況不用孩子治療，等到乳牙換完開始可以）
沒想到這陣子這位病人回來，告訴我們她孩子做了 MRC，於 MRC 白天適合配戴，所以睡眠時間配戴，但孩子會睡眠時覺拿出來，因此媽媽聽醫師建議睡覺時孩子嘴巴貼住😮
結果結果❗❗有一天媽媽巡房時發現孩子發出奇怪聲音，是嘴裡咬著MRC裝置加上嘴唇黏住所以無法順利地吞嚥口水，一點自己口水嗆到😱
珊醫師朋友聊天時，聽聞朋友六歲孩子醫師建議做 MRC，之餘請孩子張開嘴巴看看口內情況，發現，什麼需要治療需要，深入瞭解什麼醫師建議要做 MRC 🧐
珊醫師擔憂這些問題是否有過度醫療情況，因為這樣，讓珊醫師決心完成這篇文章供家長參考！
兒童重點是時機每個孩子特質給予治療，而不是想著説這個東西試試看不要緊，而導致孩子對牙科治療有了體驗或失敗經驗。試想一位孩子了一年左右嘗試，如果緊接著在做矯要花一年半時間，這樣整體療程時間可能拉長到三年，失去了兒童早期治療意義（前提是排除困難案例）

父母無不希望孩子能夠擁有牙齒，因此面兒童牙齒問題時，不能錯過扮演角色「功能性矯正MRC」，MRC是什麼？適用於哪些情況、年齡，於牙齒排列有什麼幫助？接下來跟著本文腳步，認識功能性矯正作用、適用年齡費用，後有林口MRC推薦，一起把握孩子矯正黃金期！
提到功能性矯正時，聽到是功能性矯正MRC（肌功能矯正器一種），MRC全名Myofunctional Research Center，是一間位於澳洲肌功能研究中心，而由其研發牙套Myobrace，稱為MRC牙套。因為MRC進入台灣市場時間，成為功能性矯正代名詞，但其台灣功能性矯正品牌澳洲品牌MRC之外，有美國品牌MF（Multi-Family）與日本品牌PreOrtho，因此有功能性矯正需求時，不妨諮詢專業牙醫師，瞭解品牌間差異，選擇適合自己功能性矯正產品。
接下來你介紹功能性矯正作用，並解析功能性矯正傳統差異，帶你深入認識功能性矯正。
功能性矯正主要目的是「早期矯正」，利用活動式牙套幫助兒童改善口腔習慣，例如口呼吸、舌位確、吞嚥方式錯誤。功能性矯正重點不是牙齒排列否，而是幫助孩子養成口腔習慣，奠定口腔環境，降低未來牙齒長歪的風險，像擁有土壤，樹木排列會朝向方向發展。
但有個觀念是要正確釐，並不是做了早期矯正來需要矯正牙齒，只是能夠降低成人矯正時，需要手術、拔牙可能性，或是減少打骨釘數，讓複雜療程朝向化發展，減低成人矯正程度、費用時間。
於傳統矯（例如擴弓器、局部矯正器），功能性矯正牙套孩子來説，少了鋭物件金屬裝置，可以提升孩子矯正意願，幫助早期矯正順利進行，讓孩子擁有效果。以下利用表格整理帶你瞭解2者差異：
功能性矯正黃金時期10～18歲之間，但男女發育時間，女生發育峯介於10～14歲之間；男生12～18歲。醫師會建議孩子6～8歲時進行評估，以免錯過發育峯金時期。
Invisalign（美）和Myobrace（MRC）是時下夯治療工具，兩者可以幫助矯正牙齒，改善咬合，今天讓牙醫大叔來帶你瞭解一下兩者差異哪裡吧？
Invisalign and Myobrace are two popular orthodontic treatment tools that can help correct teeth and improve bites. Today, let me explain the differences between the two.
Invisalign is suitable for a wider age range, from children to adults. Early Invisalign treatment for children usually starts at the age of 7 to 8, depending on the child’s growth rate. Myobrace is suitable for a narrower age range, recommended for children aged 5 to 15, mainly for children and adolescents. Although both are orthodontic tools, people who hear about them for the first time may not understand the difference between the two. The most common confusion is “Which method should I choose for my child?” First, you need to understand that “Invisalign” is one brand among many clear aligners, and “Myobrace” is one brand among many myofunctional orthodontic products. Other similar products include Preortho and EFline. Although the myofunctional orthodontic products have similar principles of action, there are slight differences in details.
美牙套是客製化矯裝置，衣服來比喻話，有點像訂製西裝，和牙齒服貼。每副牙套順序會有些微差異，藉由這些差異將牙齒移動到我們想要位置。牙醫師會軟體上規劃每顆牙齒位置，所以隱可以知道來牙齒矯正後排列外觀位置。
Invisalign is a custom-made orthodontic device that is comparable to a tailored suit for your teeth. Each set of aligners has slight differences that gradually shift the teeth into the desired position. The dentist plans the position of each tooth on the software, so Invisalign can clearly predict the appearance and position of the teeth after orthodontic treatment.
MRC矯正正確名稱應該是肌功能矯正，主要口腔肌肉去做訓練。MRC和美牙套，是幾套尺寸去做挑選，有點像成衣，牙弓大小去挑選適合MRC牙套尺寸。作用原理和美略有不同，MRC周圍有一些『翼』，主要是來阻擋臉頰和舌頭肌肉來降低齒列影響，搭配口腔肌肉和舌頭肌肉練習，利用牙齒周圍肌肉力量、舌頭力量加上軟性牙套來讓牙齒達到一個狀態。
The correct name for MRC correction should be myofunctional correction, which mainly focuses on training the muscles in the oral cavity. Unlike Invisalign braces, MRC uses several sets of different sizes to choose from, which is a bit like ready-to-wear clothing. The appropriate MRC brace size is selected based on the size of the dental arch. The working principle of MRC is slightly different from Invisalign; MRC has some “wings” around it, primarily to block the muscles of the cheeks and tongue and reduce their negative impact on the dental arch. By practicing exercises for the muscles in the oral and tongue areas and utilizing the power of the muscles surrounding the teeth and tongue, along with the flexibility of the braces, the teeth can achieve a state of balance.
於兩者是活動式工具，不若傳統金屬矯正器是黏在牙齒上，所以兩者要注意配戴時間。MRC另一個重點是口腔肌肉訓練，單純配戴MRC效果，平日要努力做口腔肌肉練習。
Both Invisalign and MRC are removable orthodontic appliances, unlike traditional metal braces, which are attached to teeth. Thus, both require careful attention to wearing time.Another crucial aspect of MRC treatment is oral muscle training, and merely wearing the MRC device alone is less effective. Consistent oral muscle exercises are essential for optimal results.
影片中幾個重點，MRC希望改善小朋友「口呼吸習慣」「嘴巴閉合」「舌頭位置」幾個口腔習慣。舌頭位置和閉合嘴巴有時候是因為口呼吸而造成，MRC治療時會強調舌頭置放位置，希望小朋友舌頭擺放在位置「頂上顎」，有練習吞嚥動作。你需要晚上睡覺時需配戴MRC。白日是學校時、在家寫功課時或是看電視或打電動時選擇一個時段配戴一個時MRC裝置。
MRC治療分為幾個階段：1.矯習慣，養成習慣。2.擴張上顎牙弓。3.排齊牙齒。4.維持成果。

Stage1. Habits correction, Stage2. Arch development, Stage3. Dental alignment, Stage4. Retension
為第一階段療程。有幾個動作希望小朋友要這個階段練習：1. 練習口呼吸轉成鼻子呼吸。2.訓練舌頭放在位置上。3.練習吞嚥動作。4.沒有吃飯或講話時，閉緊嘴唇。希望藉由這些動作來促進上下顎的生長，減少來後二次矯正機率。
這階段會給予第一階段MRC牙套，晚上睡覺可配戴全程而MRC會掉出時進入下一階段。
This is the first stage of the treatment. There are several actions that we want children to practice during this stage: 1. Practice switching from mouth breathing to nasal breathing. 2. Train the tongue to be in the correct position. 3. Practice the correct swallowing movement. 4. Keep lips closed when not eating or speaking. By doing these actions, we hope to promote the growth of the upper and lower jaw, reducing the likelihood of requiring orthodontic treatment in the future.
During this stage, we will provide the first stage MRC appliance, which can be worn throughout the night and must not fall out before moving on to the next st
為第二階段，是否需要視小朋友狀況而定。這階段會使用BWS上顎擴張裝置，搭配MRC牙套一起使用。目的是讓上顎擴張獲得多空間來讓牙齒排列，能促進中臉部發育。
This is the second stage, which may vary depending on the child’s condition. In this stage, a BWS maxillary expansion device is used in conjunction with the MRC orthodontic appliance. The goal is to create more space in the upper jaw for the teeth to align properly, while also promoting development of the midface.
這時會給予第二副MRC牙套，材質會第一副一點，讓牙齒可以順著MRC牙套牙弓外型進行排列。第二副牙套配戴時間和第一副一樣，會持續配戴到牙齒排列為止。
At this stage, a second set of MRC braces will be provided. The material will be slightly harder than the first set, allowing the teeth to align along the MRC brace arch shape. The daily wearing time for the second set of braces will be the same as the first set, and will continue to be worn until the teeth are properly aligned.
第三副MRC牙套目的是維持成果，小朋友會建議配戴直到生長完畢，12~14歲視生長速度有所不同。這階段於小朋友持續，有可能MRC維持器戴著戴著會磨到牙齦，這時候需要替換成傳統維持器或是尺寸MRC維持器。

The purpose of the third set of MRC appliances is to maintain the orthodontic correction achieved in the previous stages. Children are advised to continue wearing the appliance until they have finished growing, which can vary depending on growth rate, typically around 12-14 years old. During this stage, as children continue to grow, it is possible for the MRC retainer to rub against the gums, and at that point, it may need to be replaced with a conventional retainer or a larger MRC retainer.
MRC治療中問到MRC費用問題了，MRC兒童早期矯正美兒童早期矯正在費用方面誰誰呢？
答案是視狀況而定，美兒童早期矯正費用是包套，治療期間如果有牙齒跟不上牙套，或是更改治療計畫，牙醫師來説有額外技師成本，所以對患者而言少額外衍生費用。MRC兒童早期矯正不然，是單副MRC來計算，於牙醫師來説小朋友無論牙套遺失或是牙套磨損破裂，只要換一副牙套會有額外成本，所以對患者而言治療期間可能會有額外衍生費用。
MRC兒童早期矯正如果順利，MRC費用會美兒童矯正費用略低，但是有幾個狀況會有額外MRC費用產生：
如果有以上幾個狀況發生，牙醫師收取新牙套費用，多疊加幾次後MRC費用並會美兒童早期矯正。
The answer depends on the situation. The cost of Invisalign early orthodontic treatment for children is usually bundled. During the treatment period, if the teeth cannot keep up with the progress of the aligners or if the treatment plan needs to be changed, there are no additional technician costs for the dentist. Therefore, there are fewer additional costs for the patient. In contrast, MRC early orthodontic treatment for children is calculated based on a single set of MRC appliances. If a child loses or damages the appliance, the dentist will need to replace it with a new one, incurring additional costs for the patient.
If MRC early orthodontic treatment progresses smoothly, the MRC cost is generally slightly lower than the cost of Invisalign early orthodontic treatment. However, there are several situations that may result in additional MRC costs:

MRC Myobrace 是兒童矯正前預防性治療，目的預防造成日後牙齒長歪的因素，減少日後矯正和拔牙需要，利牙齒生長發育。MRC治療年齡是3到15歲之間。療程會使用一系列活動式牙套，每日白天配戴1～2時和睡眠時配戴。
近年來研究顯示，許多青少年時期和成年後問題是兒童時期顎骨發育所造成。口腔肌肉習慣包括口呼吸、舌位、吞嚥方式、以及吸手指是造成顎骨發育主要因素。過敏、氣喘、慣性張口會造成顎骨發育。上述口腔肌肉習慣問題，大部分人成長過程中有一個以上，造成我們日後齒位、咬合和臉型發育。下顎發展會限制牙齒長出的空間，阻礙牙齒長理想齒位。
MRC設計原理要修正這些口腔肌肉習慣，幫助兒童習慣正確鼻子呼吸，舌位歸正，和的吞嚥使顎骨能擴張。有足夠顎骨空間，牙齒能挺直出。
MRC治療年齡是3到15歲之間，恆齒沒完全出前。因為MRC是要透過改善口腔習慣，促使臉部和下顎正確發展，所以趁孩子發育時開始效果顯著。
