3D Printers in Dentistry: The Technological Revolution in the Dental Industry

May 10, 2023 | 3d print

Technology has revolutionized the way companies and industries do their work, and the dental sector is no exception. In recent years, 3D printing technology has been gaining ground in the dental industry, and 3D printers have become an essential tool for dental professionals. In this article, we will explore how 3D printers have become a cutting-edge technology in dentistry, and how they are changing the field of dentistry.

What is 3D printing in Dentistry?

3D printers are a not-so-new technology that allows users to create three-dimensional objects from digital models (3D models). In dentistry, 3D printers are used to manufacture dental models, orthodontic devices, surgical guides and different types of prosthetics. Digital models are created using intraoral scans of the patient's mouth and can be combined with other records such as a facial scan or tomography. These three-dimensional models are used for CAD design and later for 3D printing.

Advantages of 3D printers in dentistry

The use of 3D printers in dentistry offers a series of advantages that are revolutionizing the dental sector in all its specialties:

Precision

3D printers allow dental professionals to create prosthetics, guides and other devices with exceptional precision. The tolerance of this equipment is quite low, so it is possible to design devices in the micron range.

Speed

3D printers allow dental professionals to create prosthetics and devices in a matter of hours instead of days or weeks. This means patients can receive their treatment faster, increasing consultation efficiency and reducing errors.

Cost

Using 3D printers in dentistry can reduce production costs and ultimately reduce costs for the patient. Less chair time, number of appointments and necessary adjustments mean great savings in all dental procedures.

What is the cost of a 3D printer for dentistry?

As I mention in this video, the price of a 3D printer for dental use can vary depending on the size, type of printer, and taxes and duties in each country. However, the 2 main factors to consider are the type of printer and the size:

What you need to know about Dental 3D printing

Types of 3D printers for dentistry

Although there are some printers designed specifically for the dental industry, they are generally more expensive. However, since they are aimed at the dental profession, they are easier to use. Its value is around 3 to 5 thousand dollars, although there are some that are even more expensive.

On the other hand, hobby or desktop printers, which do not carry the "dental" label, are much cheaper and just as accurate. However, its successful use requires understanding the technology and learn all the concepts of Dental 3D printing. Its cost is around 300 to 600 dollars.

3D printer size

As you might assume, the larger the size, the higher the cost, and although a small printer is generally sufficient for office use, in some situations, such as printing models for aligners or in a dental laboratory, a large printer could be the right solution.

What materials are used for dental 3D printing?

Dental 3D printers use a specific resin for this purpose. Today there are a wide variety of materials for different uses such as:

Materiales para impresión 3D Dental
  • Resins for dental models and orthodontic models
  • Resins for surgical guides
  • Biocompatible resins for splints and intraoral devices
  • Casting resins
  • Resins with ceramic fillers for prostheses
  • Resins for impression trays
  • Resins for indirect bonding of brackets
  • Temporary resins

Each resin has specific stiffness and durability properties for its different uses in odontology

Applications of 3D printers in dentistry

3D printers have a wide variety of applications in dentistry. Some of the most common applications include:

surgical guides

3D printers are used to manufacture surgical guides designed for the placement of dental implants, periodontal surgery, endodontic approach, orthodontic mini screws, etc...

Splints or occlusal guards

It is possible to 3D print rigid and flexible materials for use in the mouth. In this way you can design and manufacture occlusal splints in a very short time and requiring very little adjustment in the mouth.

Orthodontic devices

Nowadays, the manufacturing of aligners in the clinic itself (in-office) is becoming more and more common. Additionally, 3D printers are used to make other devices, such as retainers, orthotics, or sleep apnea devices.

DENTAL PROSTHESES

There are 3D printing materials that allow the printing of provisional and permanent restorations, both for partial and total prosthetics. In addition, it is possible to design and print the metal structures of the prosthetics.

    Good evening, I want to buy a 3 D printer, to make temporary ones and I am discouraged because that means I have to buy a dental range one, which is out of my budget because there are no resins for use in the mouth for range printers. low.

    Will this information be correct?
