cross咬是一种影响牙齿对齐方式的牙齿条件。拥有杂咬的主要迹象是，嘴巴闭合或休息时，上牙的上牙适合下牙后。这可能会影响嘴巴前面的牙齿或朝向嘴巴的后部。

This condition is similar to another dental condition called an咬伤. Both are types of牙齿不良牙合. The main difference between a crossbite and an underbite is that a crossbite only impacts a group of teeth, and an underbite affects them all.

A crossbite can cause complications and painful symptoms, but it’s possible to correct it with treatment from a dental professional.

This article will cover everything you’re wondering about if you suspect you or your child have a crossbite.

彼此折叠的整齐结合的下巴被认为是您口腔健康的重要迹象。

As you might guess from its name, a crossbite refers to teeth that don’t fit over each other when your mouth is closed. When you have a crossbite, entire groups of your lower teeth may fit in front of your top teeth. This condition is considered fairly common 由牙医和正畸医生。

有两个分类：前后。

  • A posterior crossbite refers to the group of lower teeth toward the back of your mouth fitting over the teeth in your top jaw.
  • 一个前咬合是指嘴巴底部的一组牙齿在顶颌骨的牙齿上安装。

A crossbite isn’t just a cosmetic problem. For adults, an ongoing crossbite can cause other symptoms. These symptoms may include:

There are two types of causes for crossbite: dental causes and skeletal causes.

遗传学

Skeletal and dental causes may be genetic. This means that if other people in your family have had a crossbite, it may be more likely that you or your child might develop the condition, too.

Circumstantial factors

There are also circumstantial factors. If your baby teeth didn’t come loose and fall out during your primary years, or if your adult teeth seemed delayed in coming in, your jawline and your other teeth may have developed a crossbite to compensate for those things.

像嘴巴呼吸和拇指一样，在童年时期吸吮的习惯可能会导致杂咬。

Crossbites are typically corrected using orthodontic devices or surgical treatment methods.

Treatment times for adults and children vary widely, depending on the severity of the crossbite. It can take anywhere from 18 months to 3 years to correct a crossbite.

If a crossbite is identified during childhood, treatment can begin before age 10. When the jaw is still developing during childhood, palate expanders can be used to widen the roof of your mouth and treat a crossbite. Traditional牙套ordental headgearmay also be used as a form of treatment.

Adults who have milder cases of crossbite can also use orthodontic treatments, including:

  • 牙套
  • retainers
  • removable palate expanders
  • elastics that are prescribed by an orthodontist

适用于更严重的横咬，下颌手术的成年人may be recommended.

下颌手术的目的是重置并正确对齐下巴。尽管它可以愈合，但您可能需要获得其他治疗方法，例如牙套，以确保骨骼固定。

Medical insurance may cover some of your crossbite treatment if it’s classified as medically necessary. That is, if your crossbite is causing side effects negatively affecting your quality of life.

在这些情况下，牙医或医生可以主张您的保险公司来支付杂货商的费用。

如果您的保险计划中包括正畸，一些牙科保险可能涵盖因抚养子女的杂交治疗。

牙科保险计划很少涵盖成年人的正畸治疗，但值得询问，尤其是如果您认为您的治疗在医学上是必要的时。

没有保险，您的费用将根据您需要纠正越野咬合所需的治疗程度而有所不同。

  • Jaw surgery is typically the most expensive option, costing over $20,000.
  • 儿童和成人的牙套的范围从3,000美元到7,000美元不等。
  • 味蕾扩展器是最简单，最负担得起的选择，降落在2,000美元至3,000美元之间。

您可以选择不纠正越野。不过，请记住，缺点超越了美学。

If you decide not to treat a crossbite, you may be more likely to develop other dental conditions. Teeth that aren’t aligned are more difficult to keep clean, which can increase your risk of dental decay and gum disease.

还有其他与未经校正的杂交有关的慢性病，​​包括TMJ和睡眠呼吸暂停。

横咬是一种常见的条件，如果未治疗，可能导致其他并发症。

There are established and proven treatment methods to treat a crossbite in adults and in children. If you believe you might have a crossbite, make an appointment with your dentist or orthodontist for a diagnosis and to plan your next steps.
