概述

在牙科中，牙冠是帽子或覆盖在牙齿的一部分上损坏的部分：

  • 破损
  • 蛀牙
  • a root canal
  • 一个大填充

牙医还可以使用牙冠来改善牙齿的外观，并用变色，或将桥或义齿固定在适当的位置。

Crowns may fully or partially cover a tooth all the way up to the gum line, depending on the purpose and the health of the tooth.

继续阅读以了解不同类型的冠，包括黄金和金合金。

今天有几种类型的冠冕。每个人都有自己的利弊。这就是他们堆积的方式：

Gold and gold alloy

黄金被用于削弱istry for tooth repair for more than4,000 years。Dentists today most often combine gold with other metals, such as palladium, nickel, or chromium. This increases the strength of the crown and reduces its cost.

黄金和金合金冠的颜色可能会出现银色或金色。这些冠很少会碎屑或破裂。它们不容易磨损，需要拔牙最小。这些冠非常耐用，可以持续数十年。

But with their metallic color, gold alloys are the least natural-looking crown material. Some people choose to put gold alloy crowns on molars that are out of sight.

瓷

瓷crowns are a popular type of all-ceramic crown. They’re the most natural-looking option but aren’t as strong as some other kinds of crowns.

Because they look so natural, porcelain crowns are most often used on front teeth, which tend to be the most visible to others.

瓷器与贵金属粘合

瓷器与贵金属制成的底座（例如黄金）结合在一起。这些牙冠相当坚固且自然。但是有时瓷帽下方的金属可以看到一条黑线。

这些牙冠的斑点较弱，可以碎裂或破裂。他们倾向于戴在对面的牙齿。许多人为前牙选择这些冠。

所有陶瓷

全陶冠通常由二氧化锆制成，这是一种强大的材料。它通常非常匹配周围牙齿的颜色。

有金属过敏的人可以舒适地佩戴这种冠状，而不会出现不良反应的风险。

但是，全陶冠通常不如粘合到贵金属的瓷器冠强。它们也可能比金属或树脂冠更多地磨损对面的牙齿。

Pressed ceramic

A pressed ceramic crown is topped with porcelain but has a base made from some other type of ceramic, such as zirconium dioxide. It gives it more strength than an all-ceramic crown. This makes the crown very durable while maintaining the more natural appearance of porcelain.

These crowns tend to last longer than those made entirely from ceramic or porcelain.

所有树脂

全黄蛋冠是由无毒牙齿色塑料和玻璃珠的混合物制成的。

这些是most affordable皇冠选项，但它们也比其他类型的皇冠更容易磨损。与粘合到贵金属的瓷器冠相比，它们更有可能破裂。

在许多情况下，全黄星冠被用作临时冠，而不是长期的永久冠。

尽管黄金合金冠的副作用很少，但它们会影响某些人。一些可能的副作用包括：

  • 发红
  • 肿胀
  • 嘴唇和嘴巴疼痛
  • gum swelling and irritation
  • lesions in the mouth (oral lichenoid reaction)
  • 过敏反应，尤其是金镍合金常见的

一些研究人员说，在牙科中使用黄金合金是 linked 有某些健康状况的风险，例如口腔癌。但是这种联系显得薄弱，今天不被理解。

研究人员建议使用抗腐蚀的金属合金。黄金对腐蚀非常抗性。

Without insurance, it may cost$2,500per gold crown and anywhere between$ 800和$ 1,500总体上每个皇冠。有了保险，可以涵盖整个过程的约50％。

Some dental insurance plans do fully or partially cover the cost of crowns. However, coverage may be limited or may not cover the procedure if the work is considered cosmetic.

如果需要保持口腔健康的牙冠，例如覆盖根管或腐烂或牙齿的牙齿时，通常会覆盖该程序。

王室的总价格取决于您的保险计划，皇冠类型，牙齿健康以及您的住所。整个过程涉及：

  • 牙科X射线
  • 体格检查
  • 皇冠本身
  • 皇冠申请
  • 通常至少一次后续约会

When it comes to capping teeth, many crown options are available. Gold and gold alloy crowns offer strength, durability, and a good value.

However, with newer materials on the market that create a more natural appearance, you may want to consider other options. Talk to your dentist to see which type of crown is best for your needs.
