Temporary crown (bridge) resin-807
Product Introduction
807 is a biocompatible, light-curable 3D printing resin material for the production of temporary crowns and bridges. Designed for 3D printing of temporary crowns and bridges by dental technicians and oral and maxillofacial surgeons, this product offers a near-natural tooth color, a translucent ivory hue.
It exhibits high mechanical strength, exceptional resistance to fracture, bending, and abrasion, and maintains a natural tooth appearance and color. Post-printing, it requires only simple surface preparation and polishing, and its ultra-low viscosity reduces material waste and speeds cleaning. It is odorless and can be used in the oral environment.

Note:
The above values may vary depending on part geometry, print settings, temperature, and post-curing. Therefore, users must test the product before use to ensure that it meets their end-use printing performance requirements.
The above values are typical values and are not considered binding material specifications or guarantees unless expressly agreed to in writing. The final results will depend on the user’s actual use. This table is for reference only.

Instructions for use
01 Printing
Before Use: Shake the liquid resin well before use. Wear gloves to clean the resin tank and build platform, ensuring the bottom of the tank is translucent.
During Use: Pour 807 resin into the 3D printer’s resin tank, then insert the dental model into the 3D printer for printing.
After Use: Use the included tools for post-processing, including a blade, diagonal pliers, tweezers, a container, gloves, and ethanol (≥95%).
02 Washing
Remove the printed model from the build platform and soak it in IPA (isopropyl alcohol) or 95% ethanol to remove excess resin. If necessary, use an ultrasonic cleaner. Be careful not to place IPA or ethanol directly in the ultrasonic cleaner’s water tank.
03 Support Removal
Remove support structures from the printed model by manually breaking them off or using pliers. Using pliers, cut the supports as close to the model surface as possible. Be careful not to scratch the model itself, as this will cause spots that are difficult to remove during sanding.
04 Post-Curing
For post-curing, the curing energy and curing time depend on the post-curing unit. For example, good surface hardness can be achieved using a 36W (12W CCFL + 24W LED) 405nm UV curing chamber or a Formlabs FormCure curing chamber at 405nm at 60°C for 15 minutes.
05 Sterilization
The cured model can be sterilized and temporarily placed in the mouth as an aid. It is recommended to sterilize the model with 70% ethanol. Do not sterilize in an autoclave.
