The quality of the dental pore is determined by the reproducibility of the patient's oral cavity with minimal error. That is why materials companies are constantly researching and developing to create the lowest errors.

The production of dental pore water begins with an error from the moment the impression is made on the rubber in the dentist. Comatic ratio is set for each material in order to minimize this. This is equally important for other materials in other fields. The impression is floated using rubber or alginate. Except for rubber, which is highly accurate, the worker can make impressions based on a rough sense for hassle or quick work. This makes a big error.

Dental laboratories that are impressed by the dentist work on plaster to make it as close as possible to the patient's mouth. At this time, plastering works through coma rain to make small errors, but the reality depends on the sense of time and hassle.

If the model is made by the gypsum work, the pore starts to be made of a material called wax. After making waxes to make the incoming teeth, the most important and basic task is to make the powder, which is the material that stays at high temperatures for pre-summoning work to replace the wax with other materials such as metal and ceramics . At this time, the biggest error occurs and how to minimize the error is the key.

The powder is different depending on the material for manufacturing the pore water. However, in reality, most of the places where the accurate measurement is omitted by using the scale due to the production time and troublesome work, and still work by the sense.

In addition, the pores may have different results according to weather, season, and coma ratio of the powder. If powder expansion and contraction can not be caught properly, it takes more time and manpower to adjust to the model manually before completion. There is a problem in that it takes more time to iron out the task in order to shorten time and hassle.
