It s about the prosthodontic class that class is the difference between a cavity and an inlay

1. Different in natureThere is less tooth tissue to be removed during filling, especially when the composite resin is used for filling, so there is no need to prepare a strict hole type. During the production of inlays, it is necessary to completely remove the thin walls and inverted pits, and make preventive extensions to create a clear impression.

2. Different characteristics:Filling materials include composite resin, glass ionomer cement, amalgam, etc., which can be filled in layers until the material fills the cavity. The materials of the inlay include metal, all-porcelain, etc., which are generally processed outside the mouth.

3. The time of oral restoration is differentFillings can be done in one go and take less time to operate. The inlay is a slightly more complicated process, and after it is processed, it is completed in about a week by try-on, jaw adjustment, polishing, and cementing in the mouth.

Precautions for fillings.

on baby teeth. or large areas of young permanent teeth, making resin inlays is not only beautiful and durable, but also can restore the occlusal relationship between the upper and lower teeth and maintain the distance between the jaw and gum compared to simple filling. It is especially suitable for teeth that have already involved the cusp, incision, and occlusal surface, and need to re-establish the occlusal relationship and cannot be perfectly restored with general materials.

Discomfort may occur after filling, so it is generally recommended that you choose a professional dental hospital clinic and choose a professional inlay filling doctor to ensure the service life after filling. Secondly, you must pay attention to the care after the filling, especially in terms of personal oral hygiene and diet.

Encyclopedia - Cavity filling.

There is a difference, I guess you are a junior who has just entered the third year.

First of all, we must understand the classification of inlays, which can be classified according to the material and the number of tooth surfaces accumulated by the defect, and here it is estimated that you are confusing the classification method of the cumulative number of teeth of inlays with the second type of hole.

The second type of hole refers to the defect of the posterior maxillofacial and its adjacent surface, while the hole type of the inlay can be maxillofacial or adjudicatorial, or multifaceted.

The inlay is made of metal or porcelain or composite resin, which is a thing, and the second-class hole is just a hole type prepared for repair, which is a shape.

This is my understanding, I don't know if it will help you, I wish you progress in your studies.

It's ridiculous, and it's embarrassing to ask such a question

Go back and look at the restoration textbook, it's specific enough

Younger brother, let's read more books The materials used are different, the physical properties are different, the requirements for the preparation of the cave type are different, and the processing difficulty is also different, which is very similar, but it is definitely different.
