补牙效果不一,到底差在哪里?

即使你每天用含氟牙膏刷牙两次、按时使用牙线、避免甜食，你还是有可能出现口腔问题需要进行牙齿填充治疗。

Even though you keep brushing your teeth two times a day with fluoride toothpaste , using dental floss on schedule, and avoiding your favorite sweets, you may still have oral problems and need to do the tooth filling treatment.

如果蛀牙或外伤已经破坏了牙齿的完整性，那么你就需要对牙齿进行填充，修复受损的牙齿，防止进一步损害，使牙齿恢复到健康的状态。

If cavities or traumas already damage the integrity of tooth, then you need to do the filling to repair the damage and prevent it getting worse, letting your teeth will go back to the healthy condition.

值得庆幸的是，在过去的几十年里，现代牙科医学取得了长足的进步。为修复龋齿和牙外伤提供了多种选择，不仅实用而且美观自然。

Fortunately, in the last few decades, modern dentistry has made great achievements, which provide multiple choices for repairing decayed and damaged tooth, making it not only practical, but also beautiful and natural.

过去

Past

对于受损牙齿，医生通常采用金属合金（也就是银汞合金）作为填充物进行治疗，但这样的填充材料无论是从美观方面还是从功能方面考虑，都有所不足。

About the damaged tooth, dentist usually use metal alloy（i.e.silver amalgam）as the filler to proceed the treatment, but this kind of filler has deficiencies, from beauty and function both sides.

现在

Now

美国牙科协会（American Dental Association,简称ADA）表示：“现代牙科材料和技术的进步，为我们恢复动人和自然的笑容提供了新方法。”

American Dental Association, short for ADA, says: “the progress of modern dental materials and techniques has provide new methods for regaining our touching and natural smile.”

经过数十年的持续不断的努力，研究者们研发出了外观上更接近天然牙齿的新型填充材料，例如陶瓷和复合树脂。如今，许多人都开始选择接近牙齿颜色的复合填充材料，而非传统的金属填充物。

With decades’ constant efforts, researchers have developed new filling material which almost looks like the natural tooth in appearance, such as ceramic and composite resin. Right now, more people preferably choose this natural color recombination filler instead of traditional metal filler.

金属/银汞合金填充材料的弊病

The maladies of metal/silver amalgam filler

牙齿蕞外层为坚硬的牙釉质，使用银汞合金填充物的目的是借用其坚硬的质地来代替牙釉质，从而给牙齿更为强健的保护。然而，金属或银汞合金修复方法有很多弊病。

The outermost layer of tooth if hard enamel, so we use the same hard silver amalgam fillers replace enamel, giving our tooth strong protection. But, metal or silver amalgam repair treatment has all kinds of malady.

• 视觉上不雅观

• Visually not nice

深色的金属填充物在一排白色的牙中间非常显眼，并且随着时间的流逝，颜色会加深。

The dark metal fillers look appealing among the white teeth, and it will look darker as the time goes on.

• 医生需要磨掉患者牙齿的一大部分，才能腾出位置给金属填充物。
  

• Dentist need to grind off a big part from tooth to give space to the metal filler.

• 使用质地坚硬的材料进行牙齿修复可能会带来不适感。

• Hard materials used on repairing tooth will bring dis-comfortableness.

• 牙神经非常敏感，而此类填充材料无法隔绝热量和压力对牙神经带来的影响。

• Dental nerve is extremely sensitive, and this kind of filler can not isolate the influence of on tooth from heat and pressure.

• 由于缺乏弹性，银汞合金填充物难以与相对柔软、敏感的内部牙体组织有效贴合。

• Lack of elasticity, silver amalgam filler is difficult to fit the soft and sensitive inner tissue of tooth.

• 由于这种不密合，填充物之下依然有可能再次发生龋齿。

• Under the lack of closeness, decayed tooth will happen again after the filler treatment.

• 金属填充物由于硬度较大，容易裂开。

• Metal filler can easily crack because of the hardness.

新填充材料的优点

The merits of new filler

随着牙科医学的不断发展及美学理念在现代医学中的应用，研究人员努力寻找更为美观、安全、有效的、贴合牙齿的填充材料。

With the constant progressing of dentistry and aesthetic concept application in modern medicine, researchers is trying to find a new filler which is more beautiful, safe, efficient and fitting tooth.

这项研究成果为患者进行牙齿修复提供了更多的选择。目前，蕞受欢迎的是复合树脂，瓷和二氧化硅（玻璃离子）材料。

This research achievement offer clients more choices when they do the tooth treatment. Right now, the most popular materials are composite resin, porcelain and silicon dioxide (glass ionomer).

改良的新型牙齿修复材料无论是在外观上和功能上都与天然牙齿很相似，比起传统的金属填充物，确实优点良多。

Compared to the traditional metal filler, the new improved tooth treatment materials have more merits, which is more similar to the real tooth from appearance and function both sides.

复合树脂和瓷质修复材料的颜色可以和患者的牙齿颜色尽可能的保持一致，触感、质地和功能也非常接近天然牙齿。

The color of composite resin and porcelain repairing materials stays same with the real tooth , so the touch, character and function.

瓷嵌体

比起传统的材料，使用这些新的填充材料能够保留更多的天然牙齿，因为薄薄的一层复合树脂也可以和牙齿紧密贴合，因而无需磨掉太多天然牙齿来为填充腾出空间。

Compared to the traditional materials, the new materials treatment can keep more natural tooth , because only a thin layer of composite resin can stick tooth closely, which doesn’t need to grind off too much parts of natural tooth.

使用复合材料而非金属材料进行填充，能够更好地隔绝和保护牙神经，某种程度上能够让患者避免痛苦和不适。

tooth. Using composite materials instead of metal materials can preferably isolate and protect dental nerve, so in some way it will let the patients avoid pain and discomfort.

美国美容牙科学会（American Academy of Cosmetic Dentistry,简称AACD）表示：“通过修复重建的牙齿不仅在外观上与天然牙齿接近，并且功能上也是如此,在接收到咬合力之后，力量也能够通过修复的牙齿传递。”

American Dental Association, short for ADA, says: “the repaired tooth is similar to the natural tooth not only visually, but also functionally. Physical strength will be delivered through repaired tooth after receiving the biting force.

【一天口腔】牙齿修复的完美效果

这些新的修复材料不仅美观，而且比金属填充物更加耐用和稳定，并能够给剩余的牙齿提供结构上的支撑。因此，许多牙医和患者都开始选择这些新型的复合材料。

These new repairing materials are not only artistic, but also more durable and stable, and can support the rest teeth enough structurally. So the number of dentists and patients choosing new composite materials is growing.
