Dental Concerns of Marfan Syndrome (Virtual Medical Symposium Series - 01-16-2020)

Related to that is something called a posterior crossbite. You have a narrow palate and you have the upper teeth that kind of sit on the inside of the lower teeth when you bite down, which is not a proper alignment or arrangement of the teeth, that is called a posterior crossbite.
叢生と関連する所見に後交叉咬合があります。後交叉咬合とは、口蓋が狭いために、噛み合せた時に上の歯が下の歯の内側に入ることをいいます。歯並びが悪いということではありません。
And so an example of a narrow vaulted palate is shown here. What I do want to say is oftentimes you don't see people with this very specific deeply vaulted palate but this is a more extreme example.
このスライドの写真はアーチ状の狭い口蓋の例ですが、かなり極端な例ですので、これほどのものはあまり目にすることはありません。
"Does a vaulted palate mean you're going to have a dental crossbite?" Oftentimes it is correlated and why do we care about a crossbite because one of the bigger questions that people always ask is, "Do I need to get this expansion now and why?"
「アーチ状の口蓋では交叉咬合が生じやすいか」という質問については、関連することが多いという回答になります。交叉咬合を気にかける理由としては、「エキスパンダーが必要か、なぜ必要か」という質問をいつも受けます。
Well, a crossbite could be because your upper jaw is too small, not just because the teeth are not arranged properly and if you address it while the face and jaws are still developing, you are in going to be in a better situation. If you do not, it can cause, as you develop, the jaw to shift to one side, lopsided jaw growth, which in sort of medical terms would be asymmetry and this could cause a wearing down of the outer layer of enamel, of the outer layer of the tooth, which is called enamel, so that may be why some people know that they have enamel, that's wearing.
交叉咬合は上顎が狭いことで生じると考えられます。歯並びが悪いからという理由だけではありません。顔や顎が成長している段階で治療すれば、良好な結果となると考えられます。成長段階で治療を行わない場合、顎が一方に傾いてしまい、歯の最も外側にあるエナメル質がすり減ることになります。エナメル質が減っている一部の方では、こうした原因があると考えられます。
But a crossbite quite simply is when the upper teeth are on the inside of the lower teeth and that is something that again we want to fix sooner rather than later.
単純に言えば、交叉咬合は上の歯が下の歯の内側に入っている状態であり、我々は早期に治療したいと考えています。
And yes, you may often be told that you need to have expansion for the reasons cited before that we don't want to have that individual developed as an adult with these problems that will manifest perhaps even the jaw problems that we might find for people who have Marfan syndrome and joint laxity.
上で述べたような理由で、エキスパンダーを装着するように言われることも多いと思いますし、成人になってから先ほど述べた問題を抱えてほしくはありません。マルファン症候群の患者さんや関節がゆるい患者さんでは、顎の問題として現れることもあります。
