皇冠
牙冠也被称为牙帽,用于覆盖受损或严重缺损的牙齿。与只覆盖牙齿正面的牙贴面不同,牙冠覆盖整个牙齿表面。它常用于牙齿修复。
牙冠的好处
牙冠可以用来解决各种牙冠问题。牙冠看起来就像天然牙齿,您可以与牙医一起指定牙冠的形状、大小和色调。牙冠的优点包括
- 对于有大蛀牙的牙齿,牙冠可作为大锉的覆盖物
- 修复断裂、损坏或破裂的牙齿
- 牙冠是安装在种植牙柱上的假牙
- 用于修复病例,重建磨损的牙齿
- 改善牙齿外观,对于不想接受正畸矫正的病例,可帮助矫正轻度错位的牙齿
- 修整不整齐或不整齐的牙齿
- 保护大面积蛀牙或根管治疗后的脆弱牙齿,防止断裂
- 覆盖瓷贴面可能不足以覆盖的严重变色牙齿,如严重氟斑牙
牙冠还可用于制作牙桥,以替代缺失的牙缝。做完牙冠后,需要像护理天然牙齿一样护理它们。

牙冠类型
牙冠材料基本上有几种类型:
- Stainless Steel and Metal Crowns : these crowns are made from metal alloys that Kitcha rarely uses due to aesthetics and metal contents
- 瓷熔附金属牙冠(PFM):外表面由瓷制成,内表面由金属合金制成。有时也称为金属陶瓷冠。
- 全瓷牙冠:最常用的全瓷牙冠,外观自然,长期使用不会出现氧化造成黑边的问题。
- 复合牙冠:由复合树脂制成,通常用作临时牙冠。
PFM 和所有陶瓷牙冠都是在牙科技工室制作的。随着氧化锆等陶瓷技术的发展,所有的陶瓷牙冠都非常坚固且抗污。以下是制作牙冠的步骤。牙冠材料的类型决定了牙冠的价格。

在牙齿上粘接牙冠
1.治疗计划和诊断
牙医会对口腔状况和所需的牙冠治疗计划进行诊断。牙科修复师可能会拍摄 X 光片来检查牙根和牙槽骨。如果牙髓有大面积龋坏、感染或损伤,可能会先进行根管治疗,然后再开始做牙冠。
对于全口或全颌康复和美容病例,还可能需要制作研究模型或蜡型印模。
2.牙冠的牙体准备
在就牙冠材料进行讨论并确认治疗计划后,就可以为牙冠做好准备。接受牙冠的牙齿可能会被锉平,以便为牙冠腾出空间,也可能会被修整,以填补缺失的牙齿结构,从而支撑牙冠。
牙齿整形后,修复医生会通过牙模或数字口内扫描仪制作牙模。
您牙齿的模型印模或扫描图像将被发送到牙科实验室,由实验室为您制作新牙冠。对于 PFM 和烤瓷冠,会选择与周围牙齿相匹配的色调。在等待牙科技工室交付牙冠期间,会在准备好的牙齿上放置一个临时牙冠,以覆盖和保护您的牙齿。
3.牙冠粘接
当牙冠准备就绪时,牙医会取下临时牙冠,然后戴上牙冠检查颜色和是否合适。修复牙医可能会在椅旁对烤瓷冠进行调整,以达到所需的规格。
如果一切确认无误,牙冠就会被永久粘在牙齿上。使用特殊的粘合剂粘接牙冠,并在光照下牢固地固化到位。检查您的咬合情况,并进行最后的调整,以确保舒适合适。牙医会指导您如何护理牙冠。
牙冠后期护理指导
Dental crown cost varies with the material chosen. There are 3 basic types of materials used in crowns:
- 金属牙冠:由标准合金或足金制成
- PFM 牙冠:外层瓷质外壳表面与天然牙齿相似,内部为金属结构,可覆盖现有牙齿
- 全瓷牙冠:仅由瓷构成,非金属。陶瓷有多种类型,氧化锆陶瓷是目前最坚固的材料类型之一。
Standard metal alloy without gold are the basic materal and normally the most economical option. PFM crowns or porcelain fused to metal alloy crowns has an outer porcelain shell but its internal structure is made of metal alloy, typically combined with gold, in attain both aesthetics and strength. PFM dental crown cost increases with the amount of gold alloy used. The higher amount of gold, the higher the cost of your crown. In Thailand, at Kitcha dental clinic, PFM standard alloy crown cost starts at THB10,000 (estimated USD$315 per tooth) ranging upwards with the amount of gold toTHB20,000 (estimated USD$624 per tooth).
Nowadays, all ceramic crowns is the preferred material for dental crowns. An all ceramic tooth crown price is around THB18,000 (estimated USD$565 per tooth) and provides for good aesthetics without the issue of long term gum-margin stains that PFM standard alloy crowns may cause over the long run. Consult with our prosthodontist when decide on which crown material is best suited for you.
牙冠常见问题
我有哪些治疗牙齿破裂的方法?
根据牙齿破裂的程度,可以通过牙科粘接或简单地重新粘接断裂的瓷片来修复牙齿。如果牙齿已经严重破裂,您可能需要牙冠或根管治疗来修复牙齿。受伤后,请尽快去看牙医,以确定牙齿缺损的治疗方案,防止牙齿状况恶化。
戴牙冠疼吗?
在为您的牙齿准备牙冠时,牙医可能会对该区域进行局部麻醉,这样您在治疗过程中就不会感到疼痛。 治疗结束后,当麻醉药的药效消失后,您有时可能会感到临时牙冠有些敏感或牙龈有些疼痛。疼痛通常很小,而且会随着时间的推移而减轻。如果您感到疼痛,可以向牙医咨询服用止痛药。
门牙牙冠和臼齿牙冠有什么区别吗?
前牙冠的制作过程与臼齿牙冠相同。前牙冠和臼齿牙冠的唯一不同点在于,由于后牙咬合较重,修复医生可能会要求后牙使用更坚固的牙冠材料或成分。这可能会影响牙冠的成本。请咨询并讨论最适合您情况的牙冠材料。
What is dental fluorosis? And what are the dental flurosis treatment?
Fluorosis is caused by overexposure to fluoride when you are still a child when permanent teeth are being formed. Dental flurosis may identified with white markings, stains ranging from yellow to dark brown or surface irregularities.

3. For severe cases : teeth whitening followed by veneers or crowns may be recommended
Ask our cosmetic dentist by emailing us any photos of your condition who can then advise on treatment options.
