恢复提示:首次治疗与佩戴临时牙套。
护理方法：
- 初戴临时牙套，有轻度不适感，患者应耐心练习使用，逐渐适应；
- 初戴烤瓷牙时，应吃软的食物，适应后再吃正常食物（要缓慢进食，逐渐适应，以免咬伤颊舌黏膜）；
- 初期不要咬太硬的食物或者干果，比如核桃一类的干果。
8天~30天适应期

热门问题
Q1.想做合金烤瓷牙，有什么建议吗？
建议
1、钴铬烤瓷有极微小的毒性，其毒性远远小于镍铬烤瓷，对人体几乎无伤害，过敏人群接近于零，故适合经济条件一般的人群。
2、贵金烤瓷无疑是当今比较好的选择，由于适合后牙牙体修复的人群，一来材料的生物相容性好，对牙周组织和人体基本无影响，二来其强度足够，发生崩瓷的可能性低。
3、全瓷牙兼具美观和生物相容性，而且对日后核磁共振检查无影响，所以适合经济条件较好、对美观要求高的人群。
4、选择材料时也因考虑自身身体条件，若有慢性系统疾病的人群，优先选择全瓷冠，其次是贵金属烤瓷冠。
Q2.合金烤瓷牙怎么样？
比较好的是钛合金烤瓷牙，钛合金与陶瓷的结合力很好，含钛烤瓷牙，金属层会比较稳定，而且不容易扩散。好的钛合金烤瓷牙是不含铬的，对身体也没有影响，钛合金的相容性也比较好，也不会引起周围组织变色。
Q3.钛合金烤瓷牙多少钱一颗？
钛合金与陶瓷的结合力很好，含钛的合金烤瓷牙，金属层比较稳定，不容易扩散。好的钛合金烤瓷牙不含铬，对身体无影响，钛合金的生物相容性好，通常不会引起周围组织变色。钛合金烤瓷牙价格现在各地的情况不一样，大概1000元-3000元左右。

Procedure Detail
PFM Crown, also known as porcelain crown, the full name is porcelain fused metal crown, is a means of restoration for teeth; It is in the part of the defect or missing teeth, cast precious metal as the support of the core, and then in its external porcelain, to achieve the color and function of the real teeth similar repair method; It is first made of alloy metal base, and then its surface is covered with low-melting porcelain powder similar to natural teeth, and sintered and fused in a vacuum high-temperature porcelain oven.
Features
The color is natural, it can restore the teeth to be neat and white, it has the strength of metal and the beauty of porcelain crown.
Benefits
teeth whitening, teeth straightening, teeth restoration, orthodontics
Recommended
Uneven teeth, crooked teeth, large gaps, sparse teeth, teeth too thin, uneven seam

Pros
Wide range of application, in addition to the treatment of sick teeth, dental alignment, teeth color is not beautiful and other problems, can be solved; Treatment time is short, basically painless, no need to pull teeth, generally two visits can be completed; After treatment, the tooth color is realistic, natural, not deformed, durable; The price is plain, is a cost-effective choice.
Cons
Compared with precious metal porcelain teeth and all porcelain teeth, alloy porcelain teeth are inferior in color, hardness, service life and the degree of approaching real teeth. It does not completely prevent undesirable irritation and black gum lines
Unsuitable Candidate
A large number of missing teeth, with more than 4 consecutive missing front teeth and more than 2 consecutive missing posterior teeth; people with loose teeth (you can consult a professional dentist for the specific degree of looseness); people with severe periodontal disease; people with pathological changes in the root of the teeth ; Adolescents whose permanent teeth have not yet fully developed; Severe overbite, tight occlusion or those who have the habit of grinding their teeth at night.

0 days~7 days treatment period
Recovery Tips:
First treatment with temporary braces.
Aftercare methods:
- When wearing temporary braces for the first time, there will be mild discomfort. Patients should practice using them patiently and gradually adapt to them;
- When you wear porcelain teeth for the first time, you should eat soft food, and then eat normal food after you get used to it (eat slowly and adapt gradually to avoid biting the buccal and lingual mucosa);
- Do not bite too hard food or dried fruit at the beginning, such as walnuts and other dried fruits.
8 days ~ 30 days adaptation period
Recovery Tips:
Wearing a metal crown, an adaptation period.
Caring methods:
- Porcelain teeth and abutment teeth are easy to accumulate plaque. Pay attention to keep your mouth clean, develop the habit of brushing your teeth after meals, use dental floss to clean the gaps between teeth, and go to the hospital for regular checkups and tooth cleaning.
Reminder
The above postoperative care is for reference only. Due to individual differences and different surgical methods, the recovery period, stitch removal time and nursing methods will be different. The specific nursing plan is recommended to be implemented according to the doctor’s advice.
Hot issue
Q1. Do you have any suggestions for making PFM teeth?
Suggestion
1, cobalt chromium porcelain has very small toxicity, its toxicity is far less than nickel chromium porcelain, almost no harm to the human body, allergic population close to zero, so suitable for the general economic conditions of the population.
2, precious gold porcelain is undoubtedly a better choice today, because it is suitable for the people who repair the posterior teeth, on the one hand, the biocompatibility of the material is good, and it has no effect on the periodontal tissue and the human body, and on the other hand, its strength is enough, and the possibility of porcelain collapse is low.
3, full porcelain teeth have both aesthetic and biocompatibility, and have no impact on future MRI examination, so it is suitable for people with better economic conditions and high aesthetic requirements.
4, the selection of materials is also due to the consideration of their own physical conditions, if there are chronic systemic diseases of the population, the priority is to choose all-porcelain crown, followed by precious metal porcelain crown.
Q2. How is PFM teeth?
Better is titanium alloy porcelain teeth, titanium alloy and ceramic bonding force is very good, titanium porcelain teeth, the metal layer will be more stable, and not easy to spread. Good titanium alloy porcelain teeth are chromium-free, there is no effect on the body, the compatibility of titanium alloy is also better, and it will not cause discoloration of the surrounding tissues.
Q3. How much is a titanium alloy porcelain tooth?
The binding force of titanium alloy and ceramic is very good, and the metal layer of titanium alloy porcelain teeth is relatively stable and not easy to spread. Good titanium alloy porcelain teeth do not contain chromium, no impact on the body, titanium alloy biocompatibility is good, usually does not cause the surrounding tissue discoloration. Titanium alloy porcelain tooth prices are not the same everywhere, about 1000-3000 yuan.
FAQ 常见问答题
Generally, there are several common reasons: 1. Alloy porcelain teeth are in the moist environment in the mouth for a long time, releasing metal ions, causing the gums to be stained and gray lines on the gingival margins; 2. The teeth repaired by alloy porcelain teeth have gum disease. Recession, exposing the margins of the porcelain teeth.
一般有以下几种常见原因：1.合金烤瓷牙长期处于在口内湿润环境下，释放金属离子，导致牙龈着色，出现牙龈缘的灰线；2.合金烤瓷牙所修复的牙齿，发生牙龈退缩，导致烤瓷牙边缘暴露。
Under normal circumstances, no; but if it falls off, most of it is caused by secondary caries or poor retention, and you should seek medical attention in time.
正常情况下，不会的；但如果发生脱落情况，大多数是由于继发龋坏或者固位力差导致，应及时就医。
Each has its own advantages and disadvantages; cobalt-chromium alloy porcelain teeth have high metal-ceramic bonding strength, strong corrosion resistance, basically no allergic reactions, and the price is in the middle. They are a kind of metal porcelain teeth with excellent cost performance; titanium alloy porcelain teeth Metal materials are well developed, but due to the high difficulty of the manufacturing process, further research is needed for clinical application; precious metal porcelain teeth, the main components are gold and platinum, the color is closer to the color of natural teeth, the service life is longer, and it is closer to human nature. Dental shape, but the price is expensive; all-ceramic teeth, with their better optical properties, biocompatibility, and realistic color, are more natural than metal porcelain teeth, but the price is also high.
各有利弊；钴铬合金烤瓷牙，金瓷结合强度高，耐腐蚀性强，基本无过敏反应，价格居中，是一种性价比极好的金属烤瓷牙；钛合金烤瓷牙，是目前发展较好的金属材料，但由于制作工艺难度高，对临床应用有待进一步研究；贵金属烤瓷牙，主要成分是黄金与白金，颜色与天然牙颜色更接近，使用年限更长久，更接近人天然牙形态，但价格昂贵；全瓷牙，其较佳的光学性质、生物相容性、逼真色泽，要比金属烤瓷牙更自然，但价格也高。
After the first treatment, the doctor will grind the teeth, take the film, etc., and then need to wear a temporary crown for a week. After the alloy porcelain teeth are made in the factory, they will be cemented and the treatment will be completed; normal chewing will not be affected during the wearing of the temporary crown , but pay attention to maintaining oral hygiene.
首次治疗后，医生会进行磨牙、取膜等，之后需要戴一周的临时冠，待工厂将合金烤瓷牙制作完成后，再进行粘固，就完成治疗了；戴临时冠期间不影响正常咀嚼，但要注意保持口腔卫生。
