3D printer company EnvisionTEC has previewed E-IDB, a new dental material for 3D printing indirect bonding trays. The 3D printing material is being exhibited this week at IDS, the world’s largest dental show, in the German city of Cologne.

Visitors to this week’s IDS expo in Cologne will get a chance to sink their teeth into a number of dental innovations and new products. And with 3D printing playing an increasingly significant role in dentistry, the show is giving a chance to several 3D printing companies to display their filaments, 3D printers, and other products that are made specifically for dental applications.

EnvisionTEC, a 3D printing specialist headquartered in Dearborn, Michigan, manufactures a wide range of 3D printing products for the dental industry, including a number of DLP 3D printers such as the Vida, 3Dent, and P3 DDP, each of which can be used to 3D print certain dental products such as denture bases, surgical drill guides, and dental models with removable dies.

Fittingly, EnvisionTEC has made sure that it has a fresh product ready for IDS, and will this week showcase its new E-IDB material at the trade show. According to the global 3D printing company, the material builds accurate and flexible custom trays that allow for fast, accurate application of orthodontic brackets that release with ease.

Indirect bonding trays are commonly used by dentists, and allow orthodontic offices to place brackets on a patient’s teeth roughly twice as fast as individual bracket placements, which can take about two hours. With its new E-IDB material, EnvisionTEC now says that producing these trays will be similarly fast: four trays can be built in E-IDB in 45 minutes on an EnvisionTEC Vida 3D printer, and the material reportedly requires minimal post-processing.

“EnvisionTEC’s flexible E-IDB material finally allows doctors to 3D print their own indirect bonding trays right in the office rather than rely on suppliers,” said EnvisionTEC CEO Al Siblani. “This change gives clinicians more control over their trays, and how tight or loose they prefer them, as well as the entire treatment process.”

Dentists are frequently turning to 3D printing technologies to provide better care for patients. Using a 3D printing material like E-IDB, dental professionals can design a custom tray in a digital environment to match the patient’s mouth, making room for the specific brackets that should be adhered to each individual tooth. Dedicated software will then create indirect bonding trays in the precise position on a patient’s tooth to shorten treatment times.

The tray can then be 3D printed in the special material, after which a technician places the individual brackets into the tray. The 3D printed tray is then placed into a patient’s mouth, lining up brackets to the optimal position on each tooth. When this process is complete, a UV light is used to adhere the brackets to the teeth. The guide is then removed, transferring all the individual brackets to the teeth.

EnvisionTEC’s new 3D printing material is designed to work on its Vida 3D printer, which got an upgrade in February. The Michigan-headquartered company also produces specialist 3D printing equipment and materials for other industries, including bioprinting, jewelry, aerospace, automotive, and education.

E-IDB physical properties:

  • Brookfield Viscosity: 1.1 – 1.6 Pa•s
  • Elongation at Break: 12 – 18%
  • Shore A: 80 – 90
  • Tensile Strength: 4.47 MPa
  • Tensile Modulus: 13.6 MPa
