Chin Sling :: A Revolutionary New Treatment

下巴吊帶 (Chin-Sling): 一種新的治療方法

The Chin Sling is a revolutionary new way to treat malocclusion caused by TMJ(Temporo Mandibular Joint Syndrome) without invasive dental work. A large proportion of malocclusion cases may be due to TMJ and not to a genetic misalignment of the teeth. After an initial planing, the "Chin Sling" provides support to the jaw, encourages normal wear of the teeth, and helps build muscle.

     "下巴吊帶"對於TMJ症候群所造成的咬合不正來說，是一種新的治療方式，它的優點是 能夠不進行侵入性的齒科治療。有很高比例的咬合不正病患，是由於TMJ的問題所導致，而非天生的齒列不整。在進行一次磨牙手術後使用"下巴吊帶"，能夠提供支撐下巴的力量，幫助齒槽正常的研磨和肌肉的重建。

PINTA'S DIARY

以下是病例PINTA的醫療記錄

My 3-year-old guinea pig with malocclusion was getting his molars planedabout once a month. Despite regular dental maintenance, Willie continued to
lose weight. I began observing him while he ate and while he didn't eat, andnoticed his mouth was hanging slack - always slightly ajar. A recheck with
Dr. Legendre showed his bite to be perfect. I remembered Dr. Legendre tellingme about his collection of guinea pig and chinchilla skulls with maloccluded teeth and worn down bones at the jaw (mandible). This led me to believe the problem might be the jaw (ligaments or muscles), not the teeth.

      我的天竺鼠(Willie，3歲)有咬合不正的問題，每個月需接受一次臼齒磨平的手術。雖然有規律的牙齒保健，他的體重仍不斷下降。於是我開始注意到他吃進食與非進食時間時，他的嘴巴總是鬆弛的(微開)。....Dr.Legendre...(此處略過)

We took Willie to see an animal physical therapist, Cynthia Webster. She doubted the jaw slackness was due to ligaments and suspected a muscle
problem: As he aged, his jaw muscles had become slack, making it difficult for him to chew and allowing his molars to overgrow. His muscle response was proved with an electric prod and it was concluded that he required therapy to stimulate muscle tone and something to hold his jaw in place. Something flexible, breathable and rigid.

      我們帶Willie去看一個動物物理治療師Cynthia Webster，她表示:下巴的鬆弛是由於韌帶或肌肉的問題所導致，他的下巴會隨著年紀增長而變得鬆脫，這個問題會讓他咀嚼困難，並且使臼齒過度的生長。而肌肉反應則是使用電刺激的方式進行檢查，結論是他需要接受刺激肌肉張力的治療(我猜這是電療..物理治療的一種)，以及使用某個工具拖住下巴的位
置。而這個"工具"必須要是有彈性、透氣且堅固。

I got some scrap neoprene, Velcro, and designed a Chin-Sling for jaw support. Twice a day we stimulated his jaw muscle with an electric toothbrush massage. 2 minutes each side and 1 minute under chin to stimulate the tongue muscle. The difference was remarkable. His mouth no longer hung slack. And he was a different pig. Active and lively. Cynthia Webster believes he had a chronic headache from his slack jaw and now that the muscles had been stimulated and his jaw had support, his headaches, or jaw ache, had disappeared allowing him to eat with no pain.

      我拿了一些魔鬼氈，設計了Chin-Sling做為下巴的支持。我們每隔一天使用電動牙刷按摩下巴的肌肉，每一側各2分鐘，按摩下巴1分鐘來刺激舌頭的肌肉。這麼做的效果很顯著。他的嘴巴不再鬆弛了，他不再是原本那隻豬了..(=_=)。變得很有活力。Cynthia Webster認為因為下巴鬆脫導致他患有慢性的頭痛，而現在肌肉接受適當的刺激，下巴也得到支撐，因此他的頭痛或下巴的疼痛都解除，使他能夠進食。

Willie was first diagnosed with malocclusion in November, 1999. He required planing every 4 weeks until January, 2000, when he began wearing his
Chin-Sling. He has not required any dental work since that time. His malocclusion has been controlled by wearing a Chin-Sling nightly. He is
almost 5 years old now (Aug,2001).

      Willie在1999年的11月被診斷出"咬合不正"。他每四周就需接受磨牙，一直到2000年1月。在他開始使用Chin-Sling之後，他不再需要任何的齒科治療。他的咬合不正只要在晚上戴上Chin-Sling就能得到控制。他現在快要5歲了。(2001年8月)

==============================================================================

在網頁上有指出不只上面提到的Willie有做過這個治療

還有許多病例也有接受Chi-Sling的治療，效果也不錯

但是下巴脫臼的問題真的會併發很多身體的狀況

包括腎臟、腸胃...

物理治療的路真的也要走好長好久...

這部分我沒有細看...但是似乎不是每個病例都能夠成功復原...'_'...

==============================================================================

I used 1/8" thick neoprene and velcro. Neoprene is what wetsuits are made of. It's rigid, yet flexible and breathable. It's 7 1/2 inches in length and 1
inch at it's widest part. The little "wings" attach at the back of the neck to pull the ear holes wide to remove pressure from the back of the ears. If you don't do this - the ears will swell.

Chin-Sling製作方式:(1 吋 = 2.54 cm)

使用厚度1/8吋的neoprene( http://0rz.tw/524N4 )和velcro (魔鬼氈)。neoprene是潛水衣的材質 (筆電的防震包也是)，這種材質夠堅硬、具彈性且透氣。使用長7.5吋寬1吋的neoprene。將"小翅膀"連接到頸部後方，能拉寬放置耳朵的空間，這個動作能紓解耳後承受的壓力。如果沒有這麼做的話，耳朵將會腫起。

==============================================================================

Side effects: If too tight the conjunctiva will swell. Swelling goes down upon removal or loosening of Chin-sling. There can be hair loss from constant
wearing. Hair will grow back.

可能的副作用:

 如果太緊會造成結膜腫脹，在解下或調鬆之後腫脹會得到紓解。經常佩戴的位置常會出現毛髮脫落的情況，這些毛髮在不使用chin-sling之後會自己長回來。

==============================================================================

字面解釋有點模糊

不過至少知道材質是甚麼

要製作應該就不難...

看著照片也許能夠依樣畫葫蘆...
