| 牙齿依靠神经、血管供给营养，使之坚硬并充满活力。当没有神经血液供给营养后会变得特别脆弱。还有可能在各种外力或者自身因素的情况下会造成牙冠劈裂、牙根劈裂等不可逆性的损伤。这也是为什么所有口腔医生在诊疗牙齿的时候也都有一个原则，即：牙齿能保留神经的时候尽量保留神经，在牙齿没有神经的时候尽量保存牙体(保髓保牙)。 Teeth rely on nerves and blood vessels to supply nutrients and make them hard and full of vitality. When there is no neural blood supply, nutrition becomes particularly vulnerable. It may also cause irreversible damage such as crown fracture and root splitting under various external forces or self factors. This is why all dentists when in the diagnosis and treatment of teeth have a principle, namely: the tooth nerve sparing when kept in the teeth without nerve nerve, as far as possible when the preservation of teeth (Paul pulp teeth). 在生活中，也有不少需要做牙齿修复的，牙齿修复方法多样性，我们应该如何选择呢？下面任欢医生为大家讲解。 In life, there are many need to do dental restoration, tooth repair methods diversity, how should we choose? Let's explain it to you. 一、 直接充填 First, direct filling 在牙齿缺损不大的情况下，可以选择直接充填，医生会根据牙位的情况建议选择的材料。 In the case of little tooth defect, you can choose the direct filling, and the doctor will choose the material according to the position of the tooth. 二、 间接修复(嵌体修复) Two. Indirect repair (inlay repair) 在牙齿缺损情况较大的情况下，为了保证修复的严密性和耐用程度，可以选择制取模型以后在口外制作嵌体。嵌体根据材料分为树脂嵌体和瓷嵌体。 In the case of large tooth defect, in order to ensure the tightness and durability of the repair, we can choose to make model, then make inlays in the mouth. The inlay is divided into resin inlay and ceramic inlay according to the material. ①树脂嵌体：采用高强度复合树脂材料在模型上加工成形，抛光后用树脂粘结材料粘结于牙体组织上。树脂嵌体操作简便，易修补。 Resin inlay: made of high strength composite resin on the model, and then bonded to the tooth tissue with resin adhesive material after polishing. Resin inlay is easy to operate and easy to repair. ②瓷嵌体有直接在耐火材代型上制作的烤瓷嵌体;有CAD/CAM磨削出的(emax瓷/弹性瓷)嵌体，有在模型上作蜡型包埋后铸造出的铸瓷嵌体，它们具有卓越的美观性能、生物相容性。 The porcelain inlay is made from refractory material generation type porcelain inlay; CAD/CAM grinding out (Emax / porcelain porcelain inlay, elastic) with wax embedding after casting cast porcelain inlay in the model, they are compatible with biological properties, excellent appearance. 三、 全冠修复 Three, full crown restoration 冠修复的主要差别在于材质。目前来讲有烤瓷与全瓷两种。 The main difference between crown restorations is material. At present there are two kinds of porcelain and all ceramic. ①烤瓷牙材料的硬度大于牙釉质，较脆。全瓷牙的硬度比烤瓷牙材料稍软，比牙釉质硬，质韧。 (1) the hardness of porcelain teeth is larger than that of enamel. The hardness of all ceramic teeth is slightly softer than that of porcelain teeth, which is harder than that of enamel. ②全瓷牙在磨损过程中，颜色不会发生改变，而烤瓷牙则会。 The color of all ceramic teeth will not change during the process of wear, but the porcelain teeth will. ③烤瓷牙抗裂强度要比全瓷牙好。 (3) the crack resistance of porcelain teeth is better than that of all ceramic teeth. ④全瓷牙相对于烤瓷牙来讲，制作过程相对减少，其相对误差机会也较少。 4. Compared with porcelain teeth, all ceramic teeth have relatively less manufacturing process and less chance of relative errors. ⑤烤瓷牙的金属基底层冠、瓷层厚度、烧烤牙条件和次数、着色剂、表面纹理、光源等因素会影响颜色。全瓷牙，成品全瓷牙内含颜色，并提供标准比色板。 The factors such as the thickness of the metal base, the thickness of the porcelain layer, the condition and frequency of the tooth, the color of the tooth, the surface texture and the light source affect the color of the porcelain teeth. All ceramic teeth, all porcelain teeth contain color, and provide standard shade guide. ⑥全瓷牙的生物相容性很好，不溶于唾液以及其它酸性、碱性物质，也不会造成过敏反应。而烤瓷牙由于有金属基底冠的存在，有金属过敏的病例报道以及金属微漏现象的发生。 The ciya biocompatibility is very good, do not dissolve in saliva and other acidic and alkaline substances, will not cause allergic reactions. Because of the existence of metal base crown, there are metal allergy cases and metal micro leakage phenomenon in porcelain teeth. ⑦全瓷牙多用于前牙修复。烤瓷牙可以胜任后牙固定桥等强度要求较高的固定修复。 The ciya for anterior teeth restoration. Porcelain teeth can be used as fixed restorations for the fixed strength of the posterior fixed bridge. ⑧烤瓷牙设备比较简单，费用比较低。全瓷牙的制作需特殊设备，费时，费用较高。 The porcelain dental equipment is relatively simple, relatively low cost. The manufacture of all ceramic teeth requires special equipment, which is time-consuming and costly. 以上修复方式并不指定，可以根据自身的情况选择适合自己的修复方式哦! The above repair method is not specified, you can choose your own way of repair according to their own situation! |
