When you've ever gone to the dentist, you've probably seen the doctor and the nurse there. But did you know that behind your beautiful smile, or the artificial tooth or bridge you've been given, there's someone working behind the scenes to make sure it's done right? That's what we call a dental technician or ``Dental Technician''. Sometimes they're also called ``Dental Technologist''. These people are like the artists of the dental world. Without them, it would be difficult for our dentists to do a lot of work.
What exactly does a Dental Technician do?
Simply put, a dental technician is a healthcare professional who makes and repairs artificial teeth, called prostheses, and various dental appliances that are placed in our mouths. You may not meet a dental technician directly when you go to the doctor. They often work in private labs, commercial labs, or their own labs attached to doctors' clinics.
To be a dental technician, you need to have both scientific knowledge and artistic ability. Think about it, the things they make have to fit your mouth perfectly and look natural. If you have a broken tooth repaired, or a new tooth has been put in for a missing one, you are wearing the creation of a dental technician. Even if their art is not in museums, we all have their creations in our lives.
Dental technicians use dental impressions, or molds, taken by the doctor to create models of the mouth. They then use those impressions to create things like:
- Dental bridges: Bridges that replace one or more missing teeth.
- Crowns: Caps placed to cover broken or decayed teeth.
- Dental implant abutments and crowns: Parts and crowns that are placed over the roots of artificially raised teeth.
- Dentures and implant-supported dentures: Removable dentures.
- Mouth guards: These are worn to protect your teeth while playing sports, or to stop you from grinding your teeth at night.
- Retainers: Devices that hold teeth in place after they have been adjusted.
- Veneers: Thin coverings that are glued to the front surface of teeth, used to beautify teeth.
Are there different types of Dental Technicians?
Yes, there are different specializations among dental technicians depending on the type of artificial teeth they make most often. For example, some dental technicians work with prosthodontists to make things like crowns, bridges, and dentures. Others work with orthodontics to make things like retainers and aligner trays. However, most dental technicians are able to make a variety of artificial teeth.
You may also hear things like this:
- Ceramists: These people use medical-grade porcelain to create artificial teeth. Things like crowns, bridges, and dentures fall into this category.
- Crown and bridge technicians: These people create crowns and bridges using various materials such as metals, resins, and ceramics.
- Denture lab technicians: These people make and repair complete and partial dentures, as well as implant-supported dentures.
- Orthodontic technicians: They make devices used to straighten teeth, such as clear aligner trays and retainers.
How do Dental Technicians work with dentists?
Dental technicians work very closely with your dentist. Imagine you need a crown put on your tooth. Then something like this happens:
1. The doctor takes measurements of your teeth: Your doctor will take an impression of your teeth and send it to the dental technician. Along with that, they will also send you an order form. It contains a lot of information about your teeth, such as their dimensions, photos, and tooth color. This is what tells the dental technician what your crown should look like.
2. The technician makes a model: The dental technician uses a mold of your teeth to create a full-size 3D model of your entire set of teeth. This allows them to create the new crown that fits the shape of your mouth exactly.
3. Creating the crown: Next, the dental technician creates the crown according to the instructions given by the doctor. They use various methods for this. They may cut it from a block of ceramic. Or, they may melt (sinter) the material and shape it into the shape of a tooth.
4. Final finishing and shipping: Finally, the dental technician will polish your new crown thoroughly, make it look natural, and send it back to the doctor.
5. The doctor will install the crown: The doctor will give you an appointment and ask you to come in for the new crown. Before it is permanently installed, they will check that it fits properly and matches the color of your other teeth.
The doctor and the dental technician are in constant contact throughout the entire process of making your crown. If there is a slight problem with the appearance or fit of the crown, the dental technician can adjust it until it is correct. That's why you get a crown that fits well and looks beautiful.
What's the difference between a Dental Technician, Dental Assistant, and Dental Hygienist?
It takes a whole team to run a dental office properly. Dental technicians, dental assistants, and dental hygienists are all members of this team. However, their responsibilities and scope of work are different.
- Dental Technicians: Their main job is to make and repair artificial teeth and appliances. They work less directly with patients.
- Dental Assistants: Prepare treatment rooms for the doctor, record patient information, and assist the doctor during treatment and surgery.
- Dental Hygienists: Clean your teeth, apply fluoride, and perform preventive treatments such as sealant treatments to stop cavities from forming.
All of these things together help maintain your dental health.
How to become a Dental Technician?
If you want to become a dental technician, you need to have a high school diploma or equivalent (GED). After that, you can either get on-the-job dental lab tech training or take a two-year course.
To specialize in a specific field, such as ceramics or dentures, you need to become a Certified Dental Technician (CDT) .
What is a Certified Dental Technician (CDT)?
To become a certified dental technician, candidates must pass two written exams and a practical exam. In the United States, these exams are conducted and supervised by the National Board for Certification in Dental Laboratory Technology. In Sri Lanka, these qualifications can be obtained through similar recognized institutions. A CDT can specialize in one of the following areas:
- Ceramics
- Crown and bridge
- Dental implants
- Orthodontics
- Complete dentures
- Digital dentistry
Final Take-Home Message
Many of us have had dentures fitted. But we don't always think about how much work and how many steps go into making them. Dental technicians are the silent artists of dentistry. It's because of their skill that we can be confident in our smiles, and their creations last for years.
So, the next time you look at your beautiful dentures, or see your friend getting a new crown, remember the talented dental technician behind them. Their role is truly invaluable!
