What is Resin?

For those who suffered from 밤 알바 사이트 cavities, I think the cavity repair material called resin will not be unfamiliar. Because resin is one of the most used cavity restorations and is widely used as an alternative restorative that improves the aesthetic negative elements of amalgam. We talked about this for a while in the last episode of [What are the ways to treat cavities?]. This time, we will talk about the parts that we couldn’t talk about at the time.

As I said before, resin is a repair product used to treat cavities, and it is a material that deletes the cavity and repairs (charges) that part. Compared to amalgam, which is still used a lot, it is highly regarded in many ways, so it is used a lot. So, what are the advantages of highly regarded resins?

Advantages of Resin

There are many advantages of resin. First, it’s the economic part. It is true that resin costs relatively more than amalgam compared above. However, it is cheaper than restoration items such as gold, ceramic, and tessera. So it’s true that there’s not enough strength or something like gold or ceramics or Tessera. But on the contrary, they have things that they don’t have.

The second advantage is the amount of tooth removal. To put it simply, it’s the amount of teeth that are removed to treat cavities. Since the teeth cannot be regenerated, the cavity itself must be removed by deleting the cavity immediately. However, in the case of restorations (other than resin), the amount of tooth removal is increased a little for more effective treatment.

The third advantage that follows is that the adaptation period is short. That’s what it means. This is included in the advantages of foreign matter and thermal conductivity, that is, resin. In the case of metallic restoration, the thermal conductivity is high, so the teeth are greatly affected by the temperature. And in the case of foreign substances, it’s what the restoration feels awkward. Resin is a repair product with fewer shortcomings of these two.

And day care is available. That’s what it means. Resin can be treated immediately on the same day through direct repair, and the treatment time is also possible in 30 minutes to an hour. There are many advantages in time for busy modern people. For reference, in the case of gold or ceramics, there is a process of making it by a technician and putting it on the teeth, so it takes about one to two weeks of treatment time.

The last advantage is the aesthetic part. Amalgam, gold, or metallic restoration, can be aesthetically negative in appearance because it is clearly different from the color of the color of the teeth. So a lot of people who think about aesthetics are using resin.

Disadvantages of Resin

So, isn’t resin not a disadvantage? No, everything in the world has its pros and cons. Resins have the same disadvantage. One of the disadvantages of resin is the problem of strength. Obviously, there are the advantages mentioned above, but the strength of resin is weaker than other fillings, so it can be said that the cases applied are somewhat limited.

Resins are more used to treat front tooth cavities than molars with many collisions between teeth.

But the front teeth are very aesthetically influenced. So the number of people who want an aesthetic tooth line is increasing through the [tooth molding laminate] that I mentioned before. However, the resin may be aesthetically effective at first because it is similar to the color of the teeth, but it changes over time and becomes discolored. In other words, over time, the aesthetic advantage turns into a disadvantage. This is particularly evident in the contact point (the interface) between the teeth and the resin.

Let’s go into more detail about the contact point that I just mentioned above. The discoloration of the contact point is more likely due to the material properties of the resin. The material called resin shrinks during the hardening process and it is difficult to accurately predict the extent of shrinkage, which can lead to differences in contact points.

The disadvantage of the last resin is its lifespan. In general, resins can be used for more than 10 years if they are well managed. However, since it is true that it is difficult to manage teeth, the average resin has a life span of one to three years at a short time and seven to eight years at a long time.

Despite these shortcomings, resin is widely used due to the various advantages mentioned above, and many technologies have been developed due to its high frequency of use. The discoloration of the boundary surface is also less likely to occur than before because the contact point becomes very tight as the repair technology develops.

And in terms of strength, an upgraded repair of resin called Tessera was born, so it maintains its advantages and compensates for its disadvantages. (We’ll talk about Tessera in more detail later.)

the process of resin treatment

1) Delete the part of the tooth that has a cavity
2) Rough the surface with gel on the deleted area and remove bacteria and tooth residue
– Reasons for roughing: to make the resin more adhesive to the teeth (friction)
3) After 15 to 30 seconds, drain the gel with water and dry the remaining water as needed
– Here, the quality of resin treatment is determined by the degree of drying of water, which requires high medical staff experience to effectively treat resin. (Dental clinic today)
4) Apply glue to attach the resin and teeth and repair the resin

Resin treatment is carried out in the same order as above. However, in the final step (step 4), it is recommended to use a stacking method in the process of repairing the resin. The lamination method is performed to minimize the shrinkage of the resin mentioned above, and is a method of dividing the resin several times, not at once.
