QuraCROWN is a biocompatible material developed for temporary crowns and bridges. This high-strength material can be painted with composite staining kits and polished for a realistic and natural aesthetic.
QuraCROWN 3D printing resin for temporary restorations
QuraCROWN is a biocompatible 3D printing material, developed by Ackuretta Technologies Pvt. Ltd for the
printing of temporary crowns and bridges using high resolution 3D printers. IT has high flexural strength, low
shrinkage and excellent cytocompatibility. It can be used for DLP and SLA 3D printer. The FDA certificate and CE
approval of this material will be applied in 2018.
Procedures for post-processing
Pour QuraCROWN resin into the resin tank of a 3D printer, and import the crown or bridge model into the
3D printer for printing.
Remove the printed crowns or bridges from the build platform and soak in IPA (isopropanol) or 95%
ethanol to remove the extra resin. Use an ultrasonic cleaner if necessary. Please be aware that IPA and
ethanol must NOT be placed directly in the tank of the ultrasonic cleaner.
Ensure the crowns or bridges clean. Do not remain liquid resin or ethanol.
For post-curing, the curing energy and curing time depends on the post-curing unit. For example,a good
surfacehardness and biocompatibility can be achieved by 10 minutes of post-curing using a 36W (12W
CCFL + 24W LED) UV curing box at 405nm.Sterilization
Sterilization of the printed crowns or bridges using 70% ethanol is recommended.
Flexural Strength 2330 MPa
Flexural Modulus 89.94 MPa
Hardness 75 Shore D
