What is meant by taking measurements of teeth? (Dental Impressions) Let's learn everything about it in a simple way!

Have you ever heard the dentist say, "We're going to take an impression of your teeth" when you go to see a dentist? Maybe you've heard these words when you've gone to get a denture, a crown for a broken tooth, or something like that. At that point, you might be thinking, "What's this impression thing called?" Don't worry, it's very simple. Simply put, it's a mold, or measurement, of your teeth and gums. We're going to talk about all of this today.

Simply put, what is a dental impression?

Imagine you want to have a pair of shoes made that fit you perfectly. The shoemaker will first measure your foot. That's how it is with this. Before he can make a set of dentures, such as a crown, that fits your mouth perfectly, the doctor needs to get an accurate idea of ​​the shape of your teeth, gums, and the inside of your mouth. That's what a dental impression is used for.

This is like a 3D map of the inside of your mouth. After taking these measurements, a model (cast) is made of the inside of your mouth. Then, based on that model, the dentist plans the exact treatment you need and makes the things you need (like dentures).

There are two main ways to take this measurement:

1. Traditional Putty Method: In this method, the measurement is taken using a putty-like material.

2. Digital method: This uses a small handheld scanner (handheld wand) and a computer to take pictures of the inside of your mouth and create a 3D model.

Well, what kind of things are you taking this measurement for?

A dental impression is an essential part of many things in dentistry. It can help you determine the position of your teeth, the size of your teeth, and how your upper and lower teeth fit together (the way you bite). Here are some of the main reasons why you might want to take this measurement.

How many types of these mm are there?

There are generally three types of dentures that dentists use. These types are used according to the needs of each situation.

1. Preliminary Impression: This is like a rough plan. When you first see the doctor, they take these initial measurements to study the condition of your mouth and plan your treatment. The doctor will then use this to make a model of your mouth and decide what to do next.

2. Final Impression: This is the final impression. It needs to be very accurate, capturing even the smallest details. This is the final impression that will be sent to the dental laboratory to make your crown, bridge, denture, etc.

3. Bite Registration: This is done to record how your upper and lower teeth fit together when you bite. This measurement is very important so that your new dentures fit perfectly with your other teeth and you can eat properly.

What actually happens when this measurement is taken?

As we discussed earlier, there are two ways to do this. Your doctor will choose the method that is best for you.

The old method: Taking measurements with putty (Traditional Dental Putty)

This is the method that most people know and use most often.

• Step 1: The doctor will first select an impression tray made of plastic or metal that fits the size of your mouth.
• Step 2: Then, a putty-like material (usually made by mixing two colors together) is placed in the tray, placed on your upper or lower set of teeth, and pressed firmly.
• Step 3: Then you have to hold your mouth for about 2 to 3 minutes. During this time, the putty will gradually thicken like a rubber.
• Step 4: Once the putty has hardened, the doctor will remove the tray from your mouth. The putty will have an exact mold of your teeth and gums.
• Step 5: This measurement is sent to the lab. At the lab, a special type of stone powder (dental stone) is added to it and a model is created inside your mouth.

New method: Digital Scan (Digital Dental Impressions)

This is modern technology. This method is now used in many advanced dental clinics.

• In this procedure, no putty is placed in the mouth. Instead, the doctor uses a pen-like device (intraoral wand) with a small camera on the front.
• This device is placed inside your mouth and moved over your teeth and gums. As it does so, the camera takes thousands of pictures per second.
• All of those images appear instantly on a nearby computer monitor. Special software on the computer puts all of these images together to create a 3D model of the inside of your mouth.
• This method does not cause discomfort or nausea while wearing the mouthpiece. It is also very accurate.
• This 3D file is then sent electronically (like email) to the lab.

You also have these questions... Let's see the answers.

Talking about this may raise several questions in your mind. Let's find answers to those as well.

How long will this take?

The total time it takes to take a measurement using the putty method is usually less than 15 minutes. The putty is only held in the mouth for a short time, about 3-5 minutes. A digital scan can be even faster.

Does this hurt?

No. It doesn't hurt. However, some people, especially those with a gag reflex, may feel a little uncomfortable when the tray is placed in their mouth. If you have this problem, tell your doctor in advance. He or she can then do this in a way that makes it less uncomfortable for you. Taking deep breaths through your nose and distracting yourself can help reduce this discomfort.

Can teeth fall out when taking measurements?

This is something that many people fear. But a healthy tooth will never fall out when you take a measurement. However, if your tooth is already very loose, either due to gum disease or an accident, there is a very small chance that such a tooth will probably come out with the filling. But don't worry, your doctor will see to it that there is such a risk in advance and will tell you about it. If that happens, he will also take care of what needs to be done about it.

What happens after the measurement is taken?

After your impression is sent to the lab, a skilled dental technician will begin making your custom dentures. The time it takes to make this will vary depending on what you are making. For example, it will take longer to make a full set of dentures than it will to make a single crown. This can typically take anywhere from a week to several weeks.

If you are having a front tooth repaired, you will not be toothless until the new tooth is repaired. The doctor will place a temporary restoration over it.

Side effects and the importance of getting this measurement right

As we discussed earlier, there are no major side effects or risks other than nausea, so there is no reason to be afraid of this.

Now let's see why this measurement is so important.

Therefore, it is very important that you remain still and provide maximum support while the doctor takes the measurement. This will help you get a beautiful, healthy smile and something you can use without any discomfort.
