Resin filling device is a necessary instrument used to dig, fill and repair resin during resin filling operation in stomatology. It belongs to a class of medical devices according to the classification of medical device classification catalogue.
Resin filling machines are generally in the form of sets. There are many kinds of sets on the market now. These devices have different designs of handles, different packaging, some classification according to the filling teeth, and some classification according to the filling hole type, and the quantity is also different.
But no matter what suits they are, their basic functions are the same. They should conform to the steps and processes of resin filling, that is to dig resin and put it into the cavity, compact and trim.

Since it's a step-by-step process, we will have a brief understanding of different resin fillers according to their different working ends today.
There are several working ends of the resin filler. When we are filling the resin, we should put on the rubber barrier, prepare the cavity, select the resin, the molding piece should be put on, and the acid etchant adhesive should be applied. Then we start filling.
The first one is photosensitive knife. The photosensitive knife is mainly used for anterior teeth, which is convenient for us to dig resin. The flat end is used to dig resin, and then carry out horizontal pressure on the lip and tongue surface of anterior teeth. The curved end is used to shape the near and far middle radians of anterior teeth. If it is wedge-shaped defect filling, we can also use it to row gingiva. In the aesthetic repair package, photosensitive knife is better than ordinary photosensitive knife It is usually narrower and thinner, which is also convenient for more refined operation.
The second one has two cylindrical working ends, one is thick and the other is thin. When filling, we put the resin into the cavity and use this one to compact and trim. It is suitable for relatively small cavities. In some suits, this one has scale and can also be used to measure the depth of the hole.
One of the working ends of the third one is the sickle type working end that we talked about before, that is, the near middle knife. It is also used to excavate resin for horizontal pressure.
The other working end is divided into two heads, a big ball and a small ball. It is suitable for different sizes of cavities. When filling, we rub the resin into small balls to eliminate bubbles. After putting it into the cavities, we need to compact it. These two working ends are used when we press vertically downward or laterally.
Here you should have made a clear thing. We just mentioned horizontal pressure, vertical pressure and lateral pressure. Horizontal pressure is the horizontal direction with resin, which is used to smooth and cut off redundant materials. It is the horizontal force. Vertical pressure and lateral pressure are used to compact it from the top of resin or the side of resin.
Now that we know these, let's talk about the fourth one.
One of the working ends of the fourth one is a bend. Like the working end of our common probe, we often use the bend end to carve the buccal lingual fossa of the posterior teeth. Some of them are designed to look like the other working end of our probe. At this time, it is more convenient to carve the fossa of the posterior teeth near and far. When it is used, it needs to be used flexibly. Please remember Living, as long as his working end is like a probe, it is generally used to carve the groove of the posterior teeth.
Its other working end is a cone, which is used for carving some sharp working tips and ridges of posterior teeth.
In addition to the maxillofacial groove and ridge, there were buccal groove and lingual groove in the posterior teeth. Because the buccal groove and lingual groove are usually small, I usually use the last one, which is very thin, to repair the buccal groove and lingual groove.
You should also know that the working end of flat head is generally used to dig resin, the round head is generally used to pressurize, compact resin, and the sharp head is used for trimming. Some of my friends may have different usages. Remember that sentence. Everyone has his own usage habits. Don't be rigid and flexible. We are not writing textbooks.
Young doctor friends, if the teacher wants to have resin dental prosthesis, just prepare the suit directly, observe the teacher's usage habits more, and ask more questions after the patient leaves.
If you want to be good at your work, you must first make use of your tools. We all know this principle. We hope that you can come on and earn some money, and use better equipment and materials as soon as possible to make more beautiful cases.
